Abstract:
AbstractTheoretical and philosophical underpinnings of education and activism in the Anthropocene will be enriched by an embrace of non-hegemonic thinking. Lakshmi Ashram, a small girls’ school in the Himalayan mountains of Uttarakhand, India, provides an object lesson in thinking differently: in an imbrication of education/research/activism. This article acknowledges a continuing lack of attention in the literature to local, cultural and place-based diversity in transformative learning for sustainable community. However, the central story in this article is not one of critique, but rather one of a Himalayan approach to creating the pedagogical conditions for transformation in thinking and behaviour, in a connected socio-ecological community. Writing across an intercultural space, the two authors describe their ethnographic methodologies, exploring the long-term impact of a Lakshmi Ashram education on students and inhabiting the pedagogical experience of the school. A seamless flow of socio-material practice between pedagogy, research and activism in the school’s educational approach speaks to a Gandhian philosophy-in-action that is worth considering as a contribution to global educational praxis in the Anthropocene. In telling this tale of one small school’s pedagogical philosophy, the authors aim not towards ideological posturing, but towards creating further openings in thinking differently in education.

Abstract:
Context: In India, adolescent girls face serious health problem due to socio-economic, environmental and cultural conditions as well as gender discrimination. A vast majority of girls in India are suffering from either general or reproductive morbidities. Unhygienic practices during menstruation expose them for Reproductive Tract Infections (RTI). If not treated early, it could lead to various disabilities and consequently affect their valuable lives. This study was done with the aim of estimating the magnitude of gynaecological morbidities among unmarried adolescent girls as well as to find out the relation between menstrual hygiene and RTI. Settings and Design: Cross-Sectional Observational study conducted in two randomly selected Inter colleges (one rural and one urban) of district Dehradun, Uttarakhand state. Methods and Material: A cross-sectional study was undertaken in school going unmarried adolescent girls to know their menstrual hygiene practices as well as reproductive morbidity. Data was collected by interview method using a pretested, prestructured questionnaire after taking consent. Statistical analysis used: percentages and Chi-square test. Results: Approximately 65 % of the girls reported having dysmenorrhoea and 19 % of the girls had given the history of excessive vaginal discharge with or without low backache/lower abdominal pain. Strong association was found between Reproductive Tract Infections and poor menstrual hygiene. Conclusions: Girls should be made aware of the process of menstruation and importance of maintaining its hygiene before attaining menarche. They should also be made aware about its linkages with their forthcoming reproductive health.

Abstract:
Macrobrachium assamense peninsularie length-weight relationship and Fulton’s condition factor was studied in Khoh tributary of Ram Ganga in the Garhwal Himalaya region of Uttarakhand for the period of one year from March 2009-Feb 2010. A strong positive relationship was observed between the length and weight in both the sexes (male and female) (b<3). Also when data was pooled, the growth was allometric (b<3). The values obtained from the length/weight relationship (LWR) showed that there was a high and significant correlation between the total length and weight after using the t-test for the significance of correlation.The highest correlation coefficient ‘r’ =0.94 i.e strong association between length and weight was observed. This means that as the length of the prawn increases the weight increases in the same proportion. Coefficient of determination r2 was also high (0.88) which indicated that the model used for the analysis fits the data, confirming the fitness of the model. The Fulton’s condition factor “K” was recorded highest (K = 2.0603) in March and lowest (K = 1.6195) in May in Male while in female, the condition factor (K = 2.1038) was highest in August and lowest (K = 1.5345) in October. The condition factor “K” ranges from 1.6195 to 2.0603 in male and 1.5345 to 2.1038 in female. It means the condition factor was sex and season dependent. The difference in condition factors in male and female may be attributed to the presence of ovigerous female, environmental conditions and changes in feeding intensity.

Abstract:
The present study investigated the timing and duration of phenological events of A. indica in different elevational range Kumaun Himalayan forest. A total of four sites at elevation ranging between 1,900m and 2,200m were selected and at each site 10 s were marked for observations. The phenological events, i.e. leaf bud formation, leaf bud busting, leafing, flowering bud formation, flowering bud busting, flowering, fruit/seed formation, seed fall and leaf fall were monitored. Phenological duration and asynchrony of these phenophases were determined at 10 day intervals and every 2-3 day intervals during the period of peak activities. The minimum length displayed leaf bud formation (44 days) and maximum by leaf fall (86 days) across the elevation. The environmental conditions, particularly temperature, affected the phenological patterns of A. indica. The leaf bud busting activity of A. indica was 51 days. Flowering activity started on May 1st and was extended over 76 days until July 15th. Seed fall activity was extended over 66 day across elevations. ANOVA showed the longevity of phenophases were varied significantly respective to elevations (p<0.05). Our observation showed that all the phenological events of A. indica appear early at lower (1900 m) and are delayed with increasing elevation. All corresponding phenological events were earlier at lower elevations because the optimum (9.0 to 19.5°C) is met earlier in these conditions.

Abstract:
Cryptococcus albidus , isolated from the sediments of Century Pulp and Paper Mill, Lalkuan, Nainital, Uttarakhand, India, produced a copper containing oxidase, laccase, that was capable of degrading environmental pollutants. Bagasse was the most efficient inducer for laccase production. The Taguchi approach was used to optimize the growth media for five factors, i.e., pH, copper sulphate, carbon, nitrogen, and the inducer at four levels using an M-16 orthogonal array. The optimum conditions for laccase production were pH (6), CuSO4(2 mmol/L), meat peptone (0.5%), glucose (0.1%), and bagasse (1.0%). After optimization, laccase production increased seven times from 32 to 219 IU/mg. The inducer (bagasse) had maximum effect on laccase production leading to 52% increase, while pH had minimum effect with 7% increase. Growth media with laccase activity (2 U/mL) was applied for the bioremediation of dyes, effluent, and chemical compounds. These experiments showed that the growth media with laccase activity (2 U/mL) produced by Cryptococcus albidus had good potential for bioremediation of toxic and recalcitrant compounds. Further, the laccase enzyme extracted from the growth media was fractionated by DEAE-cellulose ion-exchange chromatography, and the molecular weight of the enzyme determined by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS–PAGE) was found to be 64 kDa. The activity of laccase was confirmed by native PAGE, in which ABTS was used for staining gel.

Abstract:
: Landslides have multidimensional effects on the socioeconomic as well as environmental conditions of the impacted areas. The aim of this study is the spatial prediction of landslide using hybrid machine learning models including bagging (BA), random subspace (RS) and rotation forest (RF) with alternating decision tree (ADTree) as base classifier in the northern part of the Pithoragarh district, Uttarakhand, Himalaya, India. To construct the database, ten conditioning factors and a total of 103 landslide locations with a ratio of 70/30 were used. The significant factors were determined by chi-square attribute evaluation (CSEA) technique. The validity of the hybrid models was assessed by true positive rate (TP Rate), false positive rate (FP Rate), recall (sensitivity), precision, F-measure and area under the receiver operatic characteristic curve (AUC). Results concluded that land cover was the most important factor while curvature had no effect on landslide occurrence in the study area and it was removed from the modelling process. Additionally, results indicated that although all ensemble models enhanced the power prediction of the ADTree classifier (AUCtraining = 0.859; AUCvalidation = 0.813); however, the RS ensemble model (AUCtraining = 0.883; AUCvalidation = 0.842) outperformed and outclassed the RF (AUCtraining = 0.871; AUCvalidation = 0.840), and the BA (AUCtraining = 0.865; AUCvalidation = 0.836) ensemble model. The obtained results would be helpful for recognizing the landslide prone areas in future to better manage and decrease the damage and negative impacts on the environment.

Abstract:
<p><strong>Abstract.</strong> The aim of this study is to explore the applicability of Agent Based Modelling (ABM) for the simulation of rainfall runoff and soil erosion used in a watershed monitoring activity. The study utilizes Landsat 8 imagery for Land Use Land Cover (LULC) map generation, ASTER DEM for obtaining elevation information and Climate Forecast System Reanalysis (CFSR) 36 year weather data of Asan watershed, Uttarakhand, India. In the proposed model, four major agents (raindrops, soil, elevation and water amount) have been defined for estimating the soil erosion in the region. Moreover, the direct runoff has been simulated using the Soil Conservation Service (SCS) method. The analysis of the entire time series using this approach shows that there have been substantial changes in the rainfall runoff pattern primarily due to the varying environmental conditions of the study area since the late 1980s. Furthermore, a rough estimate of the soil erosion and deposition in the area have been computed which is aligned with the theory of sediment transport and deposition. In order to automate the entire model workflow, an open source cross platform tool has been developed using Python, R and NetLogo libraries. The Open Agent Based Runoff and Erosion Simulation (OARES) tool incorporates a generic interface for analysing large spatio-temporal datasets in watershed studies. The overall analysis concludes that the results obtained using ABM are comparable to that of the conventional hydrological models, and henceforth, ABM could be utilized as a future potential hydrological modelling paradigm.</p>

Abstract:
Conditions producing disastrous flooding in Uttarakhand, India, in June 2013 differed from conditions that produced other notorious floods in the Himalayan region in recent years. During the week preceding the Uttarakhand flood, deep convection moistened the mountainsides, making them vulnerable to flooding. However, the precipitation producing the flood was not associated with a deep convective event. Rather, an eastward-propagating upper-level trough in the westerlies extended abnormally far southward, with the jet reaching the Himalayas. The south end of the trough merged with a monsoon low moving westward across India. The merged system produced persistent moist low-level flow oriented normal to the Himalayas that advected large amounts of water vapor into the Uttarakhand region. The flow was moist neutral when it passed over the Himalayan barrier, and orographic lifting produced heavy continuous rain over the region for 2–3 days. The precipitation was largely stratiform in nature although embedded convection of moderate depth occurred along the foothills, where some mild instability was being released. The Uttarakhand flood had characteristics in common with major 2013 floods in the Rocky Mountains in Colorado and Alberta, Canada.

Abstract:
The influence of Mohandas K. Gandhi on social and environmental movements in post-colonial India has been widely acknowledged. Yet, the contributions of two European associates of Gandhi, Madeleine Slade and Catherine Mary Heilemann, better known in India as Mira Behn and Sarala Behn, have not received the due attention of the academic community. This dissertation is an examination of the philosophy and social activism of Mira Behn and Sarala Behn and their roles in the evolution of Gandhian philosophy of socioeconomic reconstruction and environmental conservation in the present Indian state of Uttarakhand. Instead of just being acolytes of Gandhi, I argue that these women developed ideas and practices that drew upon from an extensive intellectual terrain that cannot be limited to Gandhi’s work. I delineate the directions in which Gandhian thought and experiments in rural development work evolved through the lives, activism, and written contributions of these two women. Particularly, I examine their influence on social and environmental movements, such as the Chipko and the Anti-Tehri Dam movements, and their roles in promoting grassroots social development and environmental sustainability in the mountain communities of Uttarakhand. Mira Behn and Sarala Behn’s integrative philosophical worldviews present epistemological, sociopolitical, ethical, and metaphysical principles and practices that have local and global significance for understanding interfaith dialog, social justice, and environmental sustainability and thus constitute a useful contribution to the theory and practice of human emancipation in our times.

Abstract:
Recent work in anthropology has translated systemic disjuncture to individual subjectivity, under the premise that "disordered" political economies cause "disordered" identities. However this work underplays the role of affect in "gathering" subjectivity amidst external transformation. The following thesis proposes a concept of "mood" as a set of conjoined, low-level affects that provides continuity in contexts of neoliberalism and change. It investigates women's "moods" in an urbanizing region of Uttarakhand, India. Drawing from ethnographic interviews in a village, and a migrant community, mood is shown to involve components of capitalist anxiety that articulate with attitudes of docility and duty. Experiences typically described as "postmodern" including "incompleteness", "estrangement" and "alienation", are common to, and produce "classical" gendered affects in both rural and urban settings. Although anxiety can be destabilizing, it joins paradoxically with these affects to lubricate women's sense of "belonging" in a place.

Abstract:
La thèse constitue une analyse physique, sociale et économique du paysage de deux villages himalayens de l’Inde (Uttarakhand) : Darkot et Sharmoli, par rapport au bourg voisin de Munsiyari qui jouit de fonctions administratives, commerciales et touristiques. Sharmoli est plus proche de Munsiyari, tandis que Darkot est distant de 7 km, et à une altitude plus basse. 173 ménages furent enquêtés. Les villages sont peuplés de Bhotias (classés Scheduled Tribes mais hindous de haute caste), Thakurs (haute caste) et ex-intouchables (Scheduled Castes). Les Bhotias pratiquaient le commerce avec le Tibet, et les autres castes étaient en position de dominés, mais à partir de 1962, avec l’arrêt du commerce et le transfert des terres des Bhotias aux Thakurs leurs anciens métayers, nombre de changements sont apparus dans la vie physique, sociale et économique des deux villages. Darkot est un village très ancien où les structures de caste, de religion et les hiérarchies demeurent très visibles dans les espaces publics comme privés, tandis que Sharmoli, construit il y a 4 ou 5 décennies, est moins marqué. Les habitants des deux villages adoptent de nouveaux types de maisons, avec de nouveaux matériaux de construction et un changement d’utilisation des pièces. Mais l’utilisation du sol à Sharmoli est marquée par le tourisme, au contraire de Darkot. L’agriculture dépasse le seuil de subsistance dans les deux cas. La majorité des hommes des deux villages est engagée dans les services (commerce) mais très peu comme fonctionnaires. L’âge moyen des actifs dans les villages dépasse 40 ans, ce qui signale l’émigration des jeunes vers les villes et la présence d’un grand nombre de retraités, notamment à Darkot. Le revenu par tête dépasse le seuil de pauvreté (3 $ par jour), mais pourrait être supérieur si les qualifications étaient supérieures et les opportunités dans les villages plus abondantes. Les femmes, notamment Bhotia, travaillent souvent dans l’artisanat, et les chambres d’hôte sont devenues une bonne source de revenu pour des ménages de Sharmoli. Globalement, le système clientéliste entre les Bhotias et les deux autres castes a disparu. Mais le paysage social de Darkot témoigne de plus d’orthodoxie dans l’espace public, puisque la religion, le temple, la caste jouent un rôle important en comparaison avec Sharmoli où dominent des fêtes modernes et profanes. La situation des femmes n’est pas très bonne dans aucun des villages, et des factions existent, notamment entre Bhotias et Thakurs. Au final, Darkot comme Sharmoli montrent les caractéristiques de la tradition et de la modernité, à travers l’analyse socio-économique des espaces privés et publics
The thesis revolves around the physical, social and economic analysis of the landscape of two Himalayan villages in Uttarakhand, India: of Darkot and Sharmoli with respect to the core Munsiyari which exhibits administrative, market and tourism functions. Sharmoli is located near the core while Darkot is situated at a distance of 7 kms. and at a lower height than Sharmoli. The villages are inhabited by Bhotias (scheduled tribe as well as high-caste Hindus), Thakurs (high-caste Hindus) and lower-caste (scheduled castes) people. Around 173 families belonging to different castes are surveyed in the two villages. Bhotias used to practice trade with Tibet and the other two castes were their subordinates, but after 1962 with the stoppage of trade and transfer of Bhotias’ land to the tiller Thakurs, a lot of changes have come about in the physical, social and economic life of both the villages. The analysis of the landscape of Darkot and Sharmoli shows that Darkot is a very old village with the presence of elements of caste, religion, hierarchy etc. in its settlement pattern of private and public spaces, while Sharmoli has been constructed in the last 4-5 decades with a lower degree of influence of social and physical factors. The inhabitants of both the villages are adopting modern-design and new types of houses with contemporary construction materials while the uses of rooms are changing as per need. Land in the Sharmoli is used more for tourism-related activities which are absent in case of Darkot, while agriculture is far from subsistence level in both the villages. Majority of the male inhabitants of both the villages are engaged in service sector activities such as labour, business, private jobs etc. while very few are in government services. The average age of the earner in both the villages is beyond 40 years which shows the out-migration of young people to the towns and cities along with the presence of a large number of pensioners, esp. in Darkot. Though the villagers are not poor with regard to per-capita income, yet their earnings are lower (i.e. around $3 per day) because of poor educational qualifications and skills, along with lack of good opportunities in the villages. Women (esp. of Bhotia caste) are engaged in handicrafts while home-stays have come up as a new and good source of income for the families in Sharmoli. Overall, the patron-client relationship between Bhotias and the other two castes in economic terms has been loosened. The social landscape of Darkot depicts more orthodoxy in public space as religion, temple, caste play an important role in Darkot in comparison to Sharmoli where modern cultural and secular festivals dominate the landscape. The situation of women is not very good in both the villages while the caste factions (esp. among Bhotias and Thakurs) are clearly visible. Hence, both Darkot and Sharmoli depict characteristics of tradition and modernity depending upon the social and economic analysis of private and public spaces

Full text
Abstract:
This thesis explores and quantifies the associations between socioeconomic variables and environmental metrics. Remotely sensed satellite data is often used to monitor environmental conditions. However, it is less frequently used for socioeconomic purposes. Several studies have attempted to use remotely sensed data to monitor socioeconomic conditions in urban areas. Non-causal associations between poverty and development and environmental conditions are frequently found in the scientific literature for rural areas of developing countries. This research uses environmental metrics derived from remotely sensed imagery from an Earth observation satellite to explore if associations, similar to those in the literature, can be found for extensive spatial areas. If non-causal associations can be found between census-based socioeconomic variables and remotely sensed environmental metrics it may be possible to use remotely sensed imagery as a limited, but valuable source of information regarding socioeconomic conditions of rural communities. Socioeconomic data is collected in national census datasets at the household level. However, this fine spatial resolution means that it is an expensive process and is typically only conducted once every 10 years. This coarse temporal resolution limits the relevance of census data for planning resource allocation by governments and targeting development assistance, especially in rapidly changing economies. Therefore, the increased temporal resolution that remotely sensed imagery offers over the traditional ground survey methods may provide a way of increasing the understanding of information available to policy makers for monitoring socioeconomic conditions. An extensive area of Assam in northeast India was used as a case study to explore the associations between socioeconomic variables derived from the Indian national census and remotely sensed environmental metrics derived from Landsat Enhanced Thematic Mapper Plus (ETM+) data. Field work first identified; (i) two socioeconomic variables that appeared to be associated with poverty which were female literacy and participation in economic alternatives to agricultural work, and; (ii) a series of land cover types that appeared to be associated with broad level socioeconomic conditions. Cloud and transparent cloud cover were removed from satellite data prior to an object-based land cover classification which defined nine land cover types identified as having potential associations with poverty in the literature and a field work study. Socioeconomic and environmental data were integrated at the village level prior to statistical analysis. No village boundary information was available and therefore, research aimed to identify the most appropriate method of approximating the village boundary using Thiessen polygons and several radial buffer zones. Statistical analyses were conducted to explore; (i) the associations between female literacy and economic alternatives to agricultural work and several environmental metrics, and; (ii) which village boundary approximation provided the lowest AIC model fit statistic. Logistic regression and generalised autoregressive error models explored the associations between socioeconomic conditions and environmental metrics on a global level. Geographically weighted logistic regression was also used to explore the spatial variation in the associations. Findings indicated that significant associations exist between female literacy and economic alternatives to agricultural work and remotely sensed environmental metrics. Many of the associations identified could be interpreted meaningfully in relation to both the understanding gained from field observations and in relation to generally accepted associations in the literature. Thus, the quantitative findings of the research were in keeping with expectations and research hypotheses, lending credibility to the associations observed by other researchers. The methods used here could be developed further and the increased temporal resolution that remotely sensed imagery offers over the traditional ground survey methods may, in the future, increase the relevance and understanding of information available to policy makers for monitoring socioeconomic conditions.

Abstract:
This thesis sets out to develop a beginning of a philosophy of water by considering philosophical implications of ecological crises currently happening along the waters of the Ganges River. In my first chapter, I give a historical account of a philosophy of water. In my second chapter, I describe various natural and cultural representations of the Ganges, accounting for physical features of the river, Hindu myths and rituals involving the river, and ecological crises characterized by the pollution and damming of the river. In my third and final chapter, I look into the philosophical implications of these crises in terms of the works of the contemporary philosopher Bruno Latour.

Abstract:
The purpose of this research was to determine the potential capacity for improved participation through community-based approaches to small hydroelectric development in the Indian Himalayas. The objectives of the research were: (1) to establish the current roles of the civic, public and private sectors in small hydro development; (2) to examine the potential for learning through participation during the development of small hydro projects; (3) to determine the potential for using community-based environmental assessment in future projects; (4) to investigate the benefits of community-driven small hydro development, and (5) to determine the implications of the findings for environmental policy and decision-making. Data were gathered using Participatory Rural Appraisal methods including semi-structured interviews, transect walks, and landscape analysis. There were five case study projects (Niti, Bampa, Jumma, Malari and Bamini/Badrinath), each in the Indo-Tibetan border region of the Indian Himalayas. The plants are all run of river, and range in capacity from 25 kW to 1.2 MW. Four of the villages had no electricity prior to the development of the small-hydro plants, while one had a prior connection to the state electrical grid (Bamini/Badrinath). The villages are inhabited by Bhotia tribespeople, and are occupied only during the summer growing season. The residents travel to lower altitude villages for the winter months. The most successful project examined, in the village of Malari, was one where community development and energy needs were considered simultaneously, and where the local community was highly involved in planning, construction and operation. The less successful projects were those where community involvement and development, sound planning, and detailed geographic information about the site were lacking in their development and operation; such as was observed in the village of Jumma, where the plant never began operations because it was damaged by an avalanche prior to its inauguration. PLEASE NOTE: As of January 2007 the State of Uttaranchal was renamed Uttarakhand. The change is not reflected in this thesis.

Abstract:
The world is facing complex and mounting environmental challenges. Increased fuel costs and increased market capacity in power generation markets is driving a transformation in power plant operations. Power plants are seeking ways to maximize revenue potential during peak conditions and minimize operational costs during off-peak conditions. Although proven natural gas reserves have increased globally by nearly 50% over the last 20 years, much of this growth has been focused in select regions and countries. In parallel to the discovery of new reserves is the increase in power demand across the globe. However, there are many regions of the globe in which power demand is not being matched by increased local supplies of natural gas, or in infrastructure required to supply natural gas to power generation assets. Given these drivers, there is growing global interest in LNG & alternate fuels. This phenomenon is driving a trend to explore the potential of using LNG fuels which can be easily transported across the globe as an alternative for power generation. In a carbon-constrained environment, the technology trend is for combustion systems capable of burning LNG fuel in combination with delivering the required operability. This paper will focus on developments in GE’s heavy duty gas turbines that enable operation on fuels with varying properties, providing fuel flexibility for sustainable power generation and better emissions compliance. GE’s turbine control system employs physics-based models of gas turbine operability boundaries (e.g., emissions, combustion dynamics, etc.), to continuously estimate current boundary levels and make adjustments as required.

Abstract:
Incessant demand for fossil derived energy and the resulting environmental impact has urged the renewable energy sector to conceive one of the most anticipated sustainable, alternative “drop-in” fuels for jet engines, called as, Bio-Synthetic Paraffinic Kerosene (Bio-SPKs). Second (Camelina SPK & Jatropha SPK and third generation (Microalgae SPK) advanced biofuels have been chosen to analyse their influence on the behaviour of a jet engine through numerical modelling and simulation procedures. The thermodynamic influence of each of the biofuels on the gas turbine performance extended to aircraft performance over a user-defined trajectory (with chosen engine/airframe configuration) have been reported in this paper. Initially, the behaviour of twin-shaft turbofan engine operated with 100% Bio-SPKs at varying operating conditions. This evaluation is conducted from the underpinning phase of adopting the chemical composition of Bio-SPKs towards an elaborate and careful prediction of fluid thermodynamics properties (FTPs). The engine performance was primarily estimated in terms of fuel consumption which steers the fiscal and environmental scenarios in civil aviation. Alternative fuel combustion was virtually simulated through stirred-reactor approach using a validated combustor model. The system-level emissions (CO2 and NOx) have been numerically quantified and reported as follows: the modelled aircraft operating with Bio-SPKs exhibited fuel economy (mission fuel burn) by an avg. of 2.4% relative to that of baseline (Jet Kerosene). LTO-NOx for the user-defined trajectory decreased by 7–7.8% and by 15–18% considering the entire mission. Additionally, this study reasonably qualitatively explores the benefits and issues associated with Bio-SPKs.

Abstract:
The need of an efficient, low cost and environment friendly hydraulic energy converter provides motivation to many researchers to contribute in the field of renewable energy. In the present investigation, one such requirement is addressed for the possibility of electrical power generation from free stream of water. The implementation of such a low head or zero head turbine does not require a dam for energy conversion, thereby making it a low cost and environmental friendly source of power generation. The present study deals with the development of a zero head vertical-axis helical water turbine, and its subsequent testing in an open channel. The main parameters that influence the performance of a helical water turbine are its blade profile, aspect ratio, helix angle, number of blades and solidity ratio. Considering these parameters and the numerical work reported in literature, a three-bladed helical turbine has been developed and tested under different loading conditions. The variation of power coefficient at various tip-speed ratios of the turbine has been investigated and analyzed.

Abstract:
Abstract The flow field associated with a liquid jet injected transversely into a crossflow, also referred as transverse jet has numerous applications in industrial, environmental and natural systems. Examples of these applications include air-breathing engines (gas turbine afterburners, ramjet and scramjet combustors), rocket engines, environmental control systems and natural flows. Earliest research of a jet in a crossflow has been motivated by applications related to environmental problems such as plume dispersal from exhaust or pipe stacks or liquid effluent dispersal in streams. This method of liquid fuel/air mixture preparation enhances flame stabilization, fuel conversion efficiency, and reduction in emissions. In gas turbine applications because of the very limited residence time available for effective fuel air mixing, detailed investigations into spray characteristics of different injector configurations in a crossflow environment is desirable for identifying promising configurations with measurements in the near field to acquire reliable spray data for development of CFD models. The velocity field of a liquid jet in the near field ejecting out from an elliptic injector into a crossflow of air were investigated experimentally at conditions relevant to gas turbine applications. A rig was set up to investigate the injection of liquid jet in subsonic cross flow with a rectangular test section of cross section measuring 100 mm by 140 mm. Experiments were done with a two injector configurations a circular 0.8mm diameter plain orifice injector and a elliptic injector with an equivalent effective area of 0.7 mm (minor axis) by 0.95 mm (major axis) which was flush mounted on the bottom plate of test section. PIV technique was used to measure droplet velocity field and distributions in the near field of the spray. Measurements were performed at a distance of 5 mm from the bottom wall in the span wise plane and the results were compared with a circular injector. It was seen that no significant differences were observed in the u and v velocity components for the elliptic and circular injectors where the geometry changes are small suggesting that parameters like velocity are not significantly affected by small changes in injector exit geometry. Further for elliptic jets it was observed that increasing the crossflow velocity and maintaining the same liquid flow rate lead to an increase in the lateral spread of the spray with no significant change in the mean vorticity values.

Abstract:
Search for potential alternative jet fuels is intensified in recent years to meet stringent environmental regulations imposed to tackle degraded air quality caused by fossil fuel combustion. The present study describes atomization characteristics of blends of jatropha-derived biofuel with conventional aviation kerosene (Jet A-1) discharging into ambient atmospheric air from a dual-orifice atomizer used in aircraft engines. The biofuel blends are characterized in detail and meet current ASTM D7566 specifications. The experiments are conducted by discharging fuel spray into quiescent atmospheric air in a fuel spray booth to measure spray characteristics such as fuel discharge behavior, spray cone angle, drop size distribution and spray patternation at six different flow conditions. The characteristics of spray cone angle are obtained by capturing images of spray and the measurements of spray drop size distribution are obtained using laser diffraction particle analyzer (LDPA). A mechanical patternator system comprising 144 measurement cells is used to deduce spray patternation at different location from the injector exit. A systematic comparison on the atomization characteristics between the sprays of biofuel blends and the 100% Jet A-1 is presented. The measured spray characteristics of jatropha-derived alternative jet fuels follow the trends obtained for Jet A-1 sprays satisfactorily both in qualitative and quantitative terms.

Abstract:
The paper presents numerical investigation using Multi environmental Eulerian PDF (MEPDF) transport model for turbulence-chemistry interaction. A turbulent flame (SM1) from Sydney swirling burner database is simulated along with two isothermal cases (N29S054, N16S159) of different swirl numbers. MEPDF methodology, a probability density function (PDF) transport modeling, exploits the advantages of the PDF transport equation and is also computationally less expensive compared to popularly used Lagrangian solution approach of PDF transport equation. In the MEPDF approach, the PDF transport equation is represented by direct quadrature method of moments with presumed shape PDF and the closure of micro-mixing is achieved by interaction by exchange with mean (IEM) model. In the current work, the reacting flow results using MEPDF are reported for SM1 flame, which is a part of the database of turbulent reacting flows and widely considered as benchmark test cases for validating turbulent-chemistry interaction models. Initially, the non-reacting flows are simulated to properly choose the boundary conditions, turbulence models as well as the grid; followed by reacting flow calculations. SKE and RKE predictions show good agreement with each other while the other turbulence model exhibit substantially different behavior, especially for non-reacting case. However, RKE model exhibits substantial improvement in the case of reacting flows.

Abstract:
The constantly growing energy needs of the world accompanied by the emphasis on environmental pollution control have driven us to look at the possibility of hydrogen as a potential source of energy for the future. However, there are serious self-ignition hazards associated with its use, which are not yet fully understood phenomena. The issue of spontaneous ignition of highly pressurized hydrogen release is an important safety concern and it is necessary to understand its mechanism in order to adopt adequate safety measures. This paper describes a numerical investigation of the flow physics of a high-pressure hydrogen gas released through a tube into the atmosphere. The formation of a strong shock wave ahead of the high-pressure hydrogen jet causes an increase in temperature of the ambient atmospheric air, thereby leading to the possibility of ignition of the hydrogen-air mixture formed at the contact surface. The analysis of the physical mechanism of shock propagation and associated temperature profiles of the flow field are presented. Parametric studies based on the numerical results of temperature profiles obtained for the various initial conditions of release pressure and tube length have been carried out to study their effects on this high-pressure hydrogen gas behaviour and how they would favour occurrence of spontaneous ignition.
