SOMMAIRE Effets tardifs: problèmes linguistiques de la période post-coloniale dans le territoire d'outre-mer français de Wallis et Futuna Contrairement à la plupart des langues du Pacifique qui ont été exposées à une influence croissante de l'anglais ou du français depuis l'arrivée des Européens dans cette région les langues des îles Wallis et Futuna sont restées relativement protégées des conséquences linguistiques du colonialisme du 19ième siècle. Ce n'est qu'après la deuxième guerre mondiale que la situation commença à changer. Alors deux événements les confrontèrent avec les mêmes problèmes sociolinguistiques que les autres îles du Pacifique avaient connus depuis des décennies, à savoir l'immigration d'un grand nombre de Wallisiens et Futuniens en Calédonie dans les années 50 et le changement du statut de protectorat en territoire en 1961. RESUMO Prokrastita kunpuŝiĝo: Postkoloniaj lingvaj problemoj en la franca transmara teritorio Valiso kaj Futuno (Centra Polinezio) Dum la plejparto de la pacifikaj lingvoj malfermiĝis al kreskanta influo de la angla kaj franca jam de la plej fruaj tagoj de kontakto, la teritorio Valiso kaj Futuno restis apenaŭ influita de la lingvaj konsekvencoj de la koloniismo de la 19-a jarcento. Du grandaj okazaĵoj - amasa migrado al Nova Kaledonio en la 1950-aj jaroj kaj transiro el la statuso de protektejo al tiu de franca transmara teritorio en 1961 - metis antaŭ la teritorion la samajn socilingvistikajn problemojn, kiuj jam de jardekoj ĉirkaŭas aliajn pacifikajn insulojn.

Wallis et futuna sont deux minuscules archipels de l'oceanie centrale dont les habitants appartiennent au groupe des polynesiens de l'ouest. L'ere des "decouvertes" apporta tres peu d'informations sur ces deux societes traditionnelles. Aussi, l'etude de la periode des premiers contacts qui s'ouvre en 1801 s'avere particulierement importante -dans le livre premier? cette these s'est attachee a etudier selon l'approche ethno-historique les societes wallisienne et futunienne lors des premiers contacts puis a analyser la logique de la mise en place des populations allogenes le livre deuxieme s'articule autour de l'arrivee des peres maristes en 1837, la conversion massive des deux archipels a la religion catholique en 1842 et la christianisation progressive des coutumes - le livre troisieme retrace en effet l'age d'or de la mission mariste a wallis et futuna jusqu'aux protectorats francais de 1888 - le premier pere polynesien est ordonne a rome en 1865 - mais des ombres persistent et leur etude explicite les limites de l'inculturation des wallisiens ou des futuniens - l'originalite de l'histoire de wallis et futuna au xixe siecle repose dans la preservation du monde traditionnel dont cette these expose les motifs et les effets generalement benefiquesWallis and futuna are two archipelageos of central oceania, whose inhabitants belong to the western polynesian group. The "discovery" era provided very little information on these two traditional societes. Therefore, the study of the period of the first contacts which opens up in 1801 proves to be of particular interest. In book one, this thesis has endeavoured to study the wallisian and futunian societes through on ethno-historial approach, at the time of the first contacts then to analysis the logic of the non-native populations settlement. Book two noots on the arrival of the marist fathers in 1837, the massive conversion of the two archipelagoes to roman catholicism in 1842 and the gradual christinization of the customs. Book three relates the golden era of the marist mission in wallis ad futuna. Until the setting up of two french protectorates in 1888. The originality of the history of wallis and futuna in the 19th century lies in the preserva tion of the traditional world whose motivations and effects, beneficial for the mostpart on the whole, are exposed in this thesis

Les iles Wallis et Futuna sont situées au centre du pacifique central et constituent un archipel administratif plus que géographique. Alors que l'archipel est catholique et français, il est situé dans un environnement océanien de langue anglaise et de tradition religieuse protestante. Il nous a paru intéressant d'analyser ici l'évolution interne de ces deux iles comme celle des milieux proches aussi dans leur évolution coloniale ancienne que contemporaine. Les objectifs de notre recherche ont porté sur les points suivants : 1) le rôle des acteurs qui ont exercé le pouvoir a Wallis Futuna dans des domaines tels que ceux : de la mission, de la monarchie, du commerce, de l'administration coloniale. 2) les changements produits par l'occidentalisation et le processus de colonisation du Pacifique central, en prenant en compte les échelles d'analyse adaptées aux thèmes traités. 3) L'analyse du processus de migration qui s'est déroulé de 1950 a 1990 entre les Wallis et la Nouvelle-Calédonie, ses formes et ses implications. 4) La situation actuelle et prévisible définissant cet archipel dans le contexte de ses dépendances et de ses alternatives en relation avec l'échelle du sud pacifique d'une part comme des environnements des micro-milieux insulaires d'autre partWallis and Futuna islands are located in the center of central pacific and constitute an unusual administrative archipelago. Indeed, the archipelago is French and catholic although being located in an English speaking and protestant oceanan environment. It seemed interesting to us to analyze the evolution of the environment of this micro-island in relation with such its old colonial evolution and also with its contemporanean one. The aim of our analyze consisted in releasing the following points : 1) the role of the actors who had exerted the power in Wallis and Futuna in such fields as : mission, monarchy, trade and colonial administration. 2) The changes related to the westernization and colonial process of central pacific, taking into account a scale of measurement adapted to it. 3) The analyze of the process of migration that took place from 1950 to 1990 towards New Caledonia, considering its forms and consequences. 4) The new set of the current and future definition of the archipelago in the context of its dependency and alternatives related to the scale of south pacific and of its micro-island environments

Full textAbstract:
Un océan, deux îles, un peuple, une culture... Un isolât rude mais autosuffisant qui n'avait que peu de contacts avec les habitants des autres îles issus des mêmes ancêtres Austronésiens. Les Polynésiens de Wallis et Futuna se retrouvent brusquement confrontés à l'altérité religieuse, civilisatrice et guerrière des européens. Dans l'arsenal de ces nouveaux arrivants dans le Pacifique sud, outre le sabre et le goupillon, en plus du commerce et de l'administration républicaine, s'implantent une nouvelle éducation au travers de l'école et de nouvelles pratiques sportives. Sur une durée de moins de 150 ans, des pans entiers de la culture originelle ont été mis à mal ou ont irrémédiablement disparu. Toutefois cette acculturation rapide dans cet espace éloigné et difficile d'accès n'a pas été totale et des traces persistent. Des syncrétismes ont eu le temps de se mettre en place, les mémoires ne se sont pas complètement effacées et une reculturation est en marche. Entre histoire, géographie humaine et anthropologie sociale, ce travail fait état des altérations successives qui ont conduit à l'évolution des pratiques physiques. Par-delà nous tenterons de comprendre les mécanismes intimes de la transformation et de la renaissance possible d'une cultureAn ocean, two islands, one people, one culture ... A rough and secluded but self-sufficient place with very few contacts with other islands and similar peoples from the same ancestors. The Polynesians of Wallis and Futuna find themselves abruptly confronted to the religious, civilizing and warlike otherness of the Europeans. In the arsenal of these new arrivals in the South Pacific, in addition to swords and brushes, in addition to trade and republican administration, a new kind of education is implanted through schooling and new sporting practices. Over a period of less than 150 years, entire facets of the original culture were altered or simply disappeared. However, this rapid acculturation in this remote and difficult-to-access place has not been total and traces persist. Syncretisms have had time to develop, the memories have not been completely erased and a reculturation is ongoing. Between history, human geography and social anthropology, this work attempts to report the successive alterations that led to the evolution of physical activities. Beyond that, we will try to understand the intimate mechanisms of the transformation and of the possible rebirth of a culture

Full textAbstract:
L’étude de l’approvisionnement du lagon de Wallis en larves de poisson a été effectuée entre juin 2002 et juin 2003 à l’aide de filets stationnaires. Au total, 158 espèces appartenant à 42 familles/taxons ont été identifiées au cours de 299 pêches. L’ensemble des 110959 larves capturées était composé principalement de Pomacentridae (34,8%), de leptocéphales (27,7%) et de Ptereleotridae (23,7%). Le suivi temporel, mené au nord de Wallis, a permis de montrer qu’à l’échelle des quartiers de lune et des mois lunaires, la richesse et la composition spécifique étaient peu variables. En revanche, d’importantes variations de l’abondance ont été décelées sur ces échelles de temps. A l’échelle de l’année, aucune tendance n’a pu être extraite des séries temporelles. La plupart des espèces abondantes ont suivi un schéma annuel de colonisation. Ces résultats suggèrent l’absence d’une forte saisonnalité de la colonisation du lagon nord de Wallis probablement liée à l’absence de saisonnalité de la reproduction. Le suivi spatial, mené au nord, à l’est et au sud de Wallis a montré, pour la majorité des espèces étudiées (75%), l’existence de corrélations positives entre les abondances des sites les plus rap- prochés (est et sud, distants de 8 km ou nord et est, distants de 1 5 km). Ce résultat suggère que les événements de colonisation s’opèrent à une échelle spatiale de l’ordre de 8-15 km plutôt qu’à l’échelle de 20 km. Les variations spatiales de la colonisation ont été persistantes à plusieurs échelles temporelles (quartier de lune, mois lunaire et année). Les trois sites ont été colonisés par des assemblages de larves distincts. La sélection active d’un habitat par les larves de poissons, ou l’influence des facteurs hydrodynamiques, pourraient expliquer cette structuration. Le processus de colonisation larvaire n’est pas indépendant des conditions environnementales. Globalement, les liens entre l’approvisionnement larvaire et les variables environnementales (la couverture nuageuse, les précipitations, la vitesse et la direction du vent, la hauteur et la direction moyenne des vagues) ont été significatifs mais faibles. Ces liens apparaissent plus fort lorsque les variations d’abondances sont étudiées par espèce. Il est probable qu’au moment de coloniser, les larves réagissent spécifiquement avec leur environnement selon leurs caractéristiques phénotypiques et ontogéniques

Full textAbstract:
Cette these propose une grille de lecture d'un important corpus de paroles de danses rassemble de 1969 a 1982 a l'ile wallis (uvea), en polynesie occidentale, par l'identification des codes sous-jacents a leur production. Le tome i preconise de constituer le domaine de la danse en domaine plenier de la recherche anthropologique en lui appliquant la methodologie qui a prevalu dans l'analyse du domaine de la parente, c'est-a-dire celle qui a reconnu un certain nombre de dimensions constitutives a la fois autonomes et interdependantes. Les reductions classiques de la danse a des gestes ou a des valeurs symboliques sont rendues caduques par le deploiement systematique d'une serie de codes elementaires organises en reseau. Sont ainsi identifies dans le cadre choregraphique concret de l'ile wallis un code des circonstances, des codes generiques, des codes textuels, des codes musicaux, des codes gestuels, un code des parures, des codes socio-politiques et des codes socio-economiques. L'absence d'un principe superieur hierarchisant les divers codes elementaires de la danse wallisienne conduit a retenir l'hypothese d'un fonctionnement general en reseau, le reseau choregraphique interne etant lie a des reseaux externes du tissu social wallisien et plus largement inter-insulaire de l'oceanie centrale. Le tome 2 fournit des elements de la tradition choregraphique de l'ile wallis (uvea) et de la zone environnante du xviie siecle au xxe siecle. Une cinquantaine de descriptions, autant de transcriptions musicales et d'illustrations et un total de 216 textes de danses de l'ile wallis -dont une recension integrale des danses de l'annee 1982- viennent documenter la base de donnees d'un reseau choregraphique relie a nombre de reseaux de la meme unite culturelle et de la meme aire culturelle. Cette these poursuit l'analyse sectorielle de la tradition orale de l'ile wallis precedemment engagee dans une these consacree aux transformations de la tradition narrative de cette ileFollowing up his study of uvean narrative tradition published in 1976, the author presents in this dissertation an analysis of 216 dance texts collected at uvea (wallis island, western polynesia). This research includes 50 musical transcriptions, 50 pictures and 100 movie, video and sound archives references which provide full information on uvean dance material. The main purpose of the dissertation is to build up a dance comprehensive system which does take into account all constitutive elements, that is to say not only genres, texts, music, movements and adornments, but also circumstances, political and economical laws and regulations. It is assumed that like in kinship studies, dance dimensions constitute at the same time autonomous and interdependant levels which are identified here as elementary codes organized within a specific network interfacing with local social networks and cross-cultural networks

Full textAbstract:
The numerical simulation of turbulent flows has a short history. About 45 years ago von Neumann (1949) and Emmons (1949) proposed an attack on the turbulence problem by numerical simulation. But one could point to a beginning 20 years later when Deardorff (1970) reported on a large-eddy simulation of turbulent channel flow on a 24x20x14 mesh and a direct simulation of homogeneous, isotropic turbulence was accomplished on a 323 mesh by Orszag and Patterson (1972). Perhaps the arrival of the CDC 6600 triggered these initial efforts. Since that time, a number of developments have occurred along several fronts. Of course, faster computers with more memory continue to become available and now, in 1994, 2563 simulations of homogeneous turbulence are relatively common with occasional 5123 simulations being achieved on parallel supercomputers (Chen et al., 1993) (Jimenez et al., 1993). In addition, new algorithms have been developed which extend or improve capabilities in turbulence simulation. For example, spectral methods for the simulation of arbitrary homogeneous flows and the efficient simulation of wall-bounded flows have been available for some time for incompressible flows and have recently been extended to compressible flows. In addition fast, viscous vortex methods and spectral element methods are now becoming available, suitable for incompressible flow with complex geometries. As a result of all these developments, the number of turbulence simulations has been increasing rapidly in the past few years and will continue to do so. While limitations exist (Reynolds, 1990; Hussaini et al., 1990), the potential of the method will lead to the simulation of a wide variety of turbulent flows. In this chapter, we present examples of these new developments and discuss prospects for future developments.

Full textAbstract:
Soil scientists used to speak of soil quality, a concept expressing a soil’s “fitness for purpose.” The prime purpose was for agriculture and the production of food and fiber. However, to the general public soil quality is a rather abstract concept and in recent years the term has been replaced by soil health. A significant reason for this change is that health is a concept that resonates with people in a personal sense. This change is epitomized in the motto “healthy soil = healthy food = healthy people” on the website of the Rodale Institute in Pennsylvania (http://rodaleinstitute.org/). One consequence of this change is an increasing focus on the state of the soil’s biology, or life in the soil, an emphasis that is expressed through the promotion of organic and biodynamic systems of farming. Viticulture and winemaking are at the forefront of this trend. For example, Jane Wilson (2008), a vigneron in the Mudgee region of New South Wales, is quoted as saying, “the only way to build soil and release a lot of the available minerals is by looking after the biology,” and Steve Wratten (2009), professor of ecology at Lincoln University in New Zealand has said, “Organic viticulture rocks! It’s the future, it really is.” This exuberance has been taken up by Organic Winegrowers New Zealand, founded only in 2007, who have set a goal of “20 by 2020,” that is, 20% of the country’s vineyards under certified organic management by the year 2020. The Cornell Soil Health Assessment provides a more balanced assessment of soil health (Gugino et al., 2009). The underlying concept is that soil health is an integral expression of a soil’s chemical, physical, and biological attributes, which determine how well a soil provides various ecosystem functions, including nutrient cycling, supporting biodiversity, storing and filtering water, and maintaining resilience in the face of disturbance, both natural and anthropogenic. Although originally developed for crop land in the northeast United States, the Cornell soil health approach is readily adapted to viticulture, as explained by Schindelbeck and van Es (2011), and which is currently being attempted in Australia (Oliver et al., 2013; Riches et al., 2013).

Full textAbstract:
The Library 2.0 is a continuation of the development of digital libraries and user oriented digital information services such as MyLibrary. The 2.0 is used to distinguish the present initiatives from the traditional library and information services denoted as Library 1.0 (Maness, 2006). Because of the technological development of electronic resources, the means of collecting, storing, managing, and using widely distributed knowledge resources stored in a variety of electronic forms has changed (Griffin, 1998). Digital libraries have been seen as libraries without walls being logical extensions to libraries (Fox & Urs, 2002) and they have shortened the distance between author and reader by giving a more direct involvement in the dissemination of information. The fundamental mission to facilitate and provide access to information and knowledge has remained, but the processes, tools, and techniques have undergone major development. The initiatives describing personalized Web services like MyLibrary (Cohen, Fereira, et al., 2000) are a further development of digital libraries, which define personalized library services to users who are Web users. This group of users expects customization and interactivity. After the initial MyLibrary initiative there have been several dozen implementations of similar projects worldwide. However, during the initial years, the adoption rates of these services reached only about 10% of the potential user community (Gibbons, 2003). It is important to look at the barriers to personalized service because this seems to be the future of the digital world and the next big challenge at hand; what challenge will the Web 2.0 services pose to the libraries where libraries share the technological and social space with the Web? New trends like personalization, self service, mobility, and technology have created a Web environment that is transforming how users are interacting with information (Bearman, 2007; Benson & Favini, 2006; Coombs, 2007).

This paper presents an analysis of heat transfer in water at supercritical conditions in bare vertical tubes. A large dataset within conditions similar to those of SuperCritical Water-cooled nuclear Reactors (SCWRs) was obtained from the Institute for Physics and Power Engineering (Obninsk, Russia). This dataset was compared to existing heat-transfer correlations from the open literature. This comparison is an extension to the previous studies done with this dataset. Previous studies have shown that existing correlations, such as the Dittus-Boelter correlation significantly overestimates the experimental heat transfer coefficient (HTC) values within the pseudocritical range; the Bishop et al. and Jackson’s correlations were also found to deviate significantly from the experimental data. The Swenson et al. correlation provided a better fit for the experimental data, as compared to the previous three correlations within some flow conditions, but deviates from data for other conditions. HTC and wall temperature values calculated with the FLUENT CFD code also deviate from the experimental data within some conditions. After analyzing the existing correlations, it was decided to develop a better correlation for predicting HTC. Since the Swenson et al. correlation seems to be the best candidate for predicting the experimental data; it was selected as a basis for developing a new empirical correlation. The primary difference of the Swenson et al. approach is that it uses the majority of thermophysical properties at the wall temperature as opposed to those used at bulk-fluid temperatures in other models. Calculating various thermophysical properties based on wall temperature seems to give much better results in terms of accuracy. To obtain a basic empirical correlation, a dimensional analysis was conducted using a combination of various dimensionless terms. This approach was combined with the experimental dataset at the normal heat-transfer regime using statistical analysis. The final correlation showed the best fit for the experimental dataset within a wide range of flow conditions. The calculated wall temperatures were within (±15%) for the analyzed dataset, which is a considerable improvement from the previous correlations. The accuracy of calculated values was further improved when a term was added to the correlation that accounted for the entrance effect in bare tubes. Thus, the new correlation presented in this paper can be used for HTC calculations in supercritical-water heat exchangers at SCW Nuclear Power Plants (NPPs) in case of the indirect cycle, in heat exchangers for co-generation of hydrogen from supercritical water side, for a preliminary heat-transfer calculations in SCWR fuel channels as a conservative approach. It can also be used for future comparisons with other independent datasets, with bundled data, for the verification of computer codes for SCWR core thermalhydraulics and for the verification of scaling parameters between water and modeling fluids.

This paper presents selected results on heat transfer to supercritical water flowing upward in a 4-m-long vertical bare tube. Supercritical water heat-transfer data were obtained at pressures of about 24 MPa, mass fluxes of 200 – 1500 kg/m2s, heat fluxes up to 884 kW/m2 and inlet temperatures from 320 to 350°C for several combinations of wall and bulk-fluid temperatures that were below, at or above the pseudocritical temperature. In general, the experiments confirmed that there are three heat-transfer regimes for forced convective heat transfer to water flowing inside tubes at supercritical pressures: (1) normal heat-transfer regime characterized in general with heat transfer coefficients (HTCs) similar to those of subcritical convective heat transfer far from critical or pseudocritical regions, which are calculated according to the Dittus-Boelter type correlations; (2) deteriorated heat-transfer regime with lower values of the HTC and hence higher values of wall temperature within some part of a test section compared to those of the normal heat-transfer regime; and (3) improved heat-transfer regime with higher values of the HTC and hence lower values of wall temperature within some part of a test section compared to those of normal heat-transfer regime. These new heat-transfer data are applicable as a reference dataset for future comparison with supercritical-water bundle data and for a verification of scaling parameters between water and modeling fluids. Also, these HTC data were compared to those calculated with the original Dittus-Boelter and Bishop et al. correlations. The comparison showed that the Bishop et al. correlation, which uses the cross-section average Prandtl number, represents HTC profiles more correctly along the heated length of the tube than the Dittus-Boelter correlation. In general, the Bishop et al. correlation shows a good agreement with the experimental HTCs outside the pseudocritical region, however, overpredicts the experimental HTCs within the pseudocritical region. The Dittus-Boelter correlation can also predict the experimental HTCs outside the pseudocritical region, but deviates significantly from the experimental data within the pseudocritical region. It should be noted that both these correlations cannot be used for a prediction of HTCs within the deteriorated heat-transfer regime.

In support of developing SuperCritical Water-cooled Reactors (SCWRs), studies are currently being conducted for heat-transfer at supercritical conditions. This paper presents an analysis of heat-transfer to SuperCritical Water (SCW) flowing in bare vertical tubes as a first step towards thermohydraulic calculations in a fuel-channel. A large set of experimental data, obtained in Russia, was analyzed. Two updated heat-transfer correlations for forced convective heat transfer in the normal heat transfer regime to SCW flowing in a bare vertical tube were developed. It is expected that the next generation of water-cooled nuclear reactors will operate at supercritical pressures (∼25 MPa) with high coolant temperatures (350–625°C). Currently, there are no experimental datasets for heat transfer from power reactor fuel bundles to the fuel coolant (water) available in open literature. Therefore, for preliminary calculations, heat-transfer correlations obtained with bare tube data can be used as a conservative approach. The analyzed experimental dataset was obtained for SCW flowing upward in a 4-m-long vertical bare tube. The data was collected at pressures of about 24 MPa for several combinations of wall and bulk-fluid temperatures that were below, at, or above the pseudocritical temperature. The values for mass flux ranged from 200–1500 kg/m2s, for heat flux up to 1250 kW/m2 and inlet temperatures from 320–350°C. The Mokry et al. correlation was developed as a Dittus-Boelter-type correlation, with thermophysical properties taken at bulk-fluid temperatures. Alternatively, the Gupta et al. correlation was developed based on the Swenson et al. approach, where the majority of thermophysical properties are taken at the wall temperature. An analysis of the two updated heat-transfer correlations is presented in this paper. Both correlations demonstrated a good fit (±25% for Heat Transfer Coefficient (HTC) values and ±15% for calculated wall temperatures) for the analyzed dataset. Thus, these correlations can be used for preliminary HTC calculations in SCWR fuel bundles as a conservative approach, for SCW heat exchangers, for future comparisons with other independent datasets and for the verification of computer codes for SCWR core thermohydraulics.

Abstract Particle ingestion into turbine engines is a widespread problem that can cause significant degradation in engine service life. One primary damage mechanism is deposition of particulate matter in internal cooling passages. Musgrove et al. proposed a compact particle separator that could be installed between the combustor bypass exit and turbine vane cooling passage inlet. The design had small pressure losses but provided limited particle separation, and its performance has proved difficult to replicate in subsequent experiments. Borup et al. recently developed a Magnetic Resonance Imaging (MRI) based technique for making full-field, 3D measurements of the mean particle concentration distribution in complex flows. A particle separator based on the Musgrove et al. design was fabricated out of plastic using 3D printing. The primary difference from earlier designs was the addition of a drain from the collector, through which 3% of the total flow was extracted. The separator efficiency was measured at two Reynolds numbers, using water as the working fluid and 33-micron titanium microspheres to represent dust particles. Particle Stokes number was shown to play the dominant role in determining efficiency across studies. MRI was used to obtain the 3D particle volume fraction and 3-component velocity fields. The velocity data showed that flow was poorly distributed between the separator louvers, while the collector flow followed the optimal pattern for particle retention. The particle distribution data revealed that strong swirling flow in the collector centrifuged particles towards the outer wall of the collector and into a partitioned region of quiescent flow, where they proceeded to exit the collector via the drain. Future designs could be improved by re-arranging the louvers to produce a more uniform flow distribution, while maintaining the effective collector design.

In large eddy simulation of turbulent flow, because of the spatial filter, inhomogeneity and anisotropy affect the subgrid stress via the mean flow gradient. A method of evaluating the mean effects is to split the subgrid stress tensor into “rapid” and “slow” parts. This decomposition was introduced by Shao et al. (1999) and applied to A Priori tests of existing subgrid models in the case of a turbulent mixing layer. In the present work, the decomposition is extended to the case of a passive scalar in inhomogeneous turbulence. The contributions of rapid and slow subgrid scalar flux, both in the equations of scalar variance and scalar flux, are analyzed. A Priori numerical tests are performed in a turbulent Couette flow with a mean scalar gradient. Results are then used to evaluate the performances of different popular subgrid scalar models. It is shown that existing models can not well simulate the slow part and need to be improved. In order to improve the modeling, an extension of the model proposed by Cui et al. (2004) is introduced for the slow part, whereas the Scale-Similarity model is used reproduce the rapid part. Combining both models, A Priori tests lead to a better performance. However, the remaining problem is that none eddy-diffusion model can correctly represent the strong scalar dissipation near the wall. This problem will be addressed in future work.

Previous study (Pioro et al., 2008) confirmed that there are three heat-transfer regimes for forced convective heat transfer to water flowing inside tubes at supercritical pressures: (1) Normal heat-transfer regime; (2) Deteriorated heat-transfer regime, characterized by lower than expected heat transfer coefficients (HTCs) (i.e., higher than expected wall temperatures) than in the normal heat-transfer regime; and (3) Improved heat-transfer regime with higher-than-expected HTC values, and thus lower values of wall temperature within some part of a test section compared to those of the normal heat-transfer regime. The HTC data were compared to those values calculated with the Dittus-Boelter and Bishop et al. correlations. The comparison showed that the Bishop et al. correlation represents more closely HTC profiles along the heated length of the tube than the Dittus-Boelter correlation. The latter correlation deviates significantly from experimental data within the pseudocritical range. However, outside the pseudocritical region, the Dittus-Boelter correlation can predict closely experimental HTCs. It should be noted that neither of these correlations can be used for prediction of HTCs within the deteriorated heat-transfer regime. An updated heat-transfer correlation is presented in this paper for forced convective heat transfer in the normal heat-transfer regime to supercritical water in a bare vertical tube. It has demonstrated a good fit (±25%) for the analyzed dataset. This correlation can be used for future comparisons with other independent datasets, with bundled data, for the verification of computer codes for SCWR core thermalhydraulics and for the verification of scaling parameters between water and modeling fluids.

The explosively loaded cylinder is further studied as an experimental method to improve dynamic fracture and fragmentation modeling. Details of the cylinder configuration are investigated to prescribe controlled loading conditions of uniaxial stress and plane strain. Commonly used fracture models, e.g. Johnson-Cook, are calibrated with strain at fracture under such controlled conditions. Earlier works by Goto, et al [1] had used thin-walled tubes to provide plane strain loading and shorter “rings” to establish uniaxial stress conditions. This paper extends on that work to look at alternative cylinder dimensions and metals of interest. A tungsten alloy, Aero 224, and a high strength steel, Eglin Steel (ES-1), are the subject metals. Dynamic, continuum-mechanics based modeling and simulations evaluated whether the stress triaxiality conditions are being met as design parameters of cylinder wall-thickness, explosive type, and initiation configuration. Experiments conducted for this effort, reported in greater detail by Weiderhold [2], provided precise measurement of the cylinder expansion process and fragmentation distributions. An explosively driven metal event is usually considered highly transient and multi-dimensional in stress; however, selective design of the system can result in a controlled experimental configuration. The analysis shows that the ductile ES-1 steel cylinder and rings do establish the desired plane strain and uniaxial stress conditions, respectively, as the cylinder expands to failure. Ultra-high speed photography experiments verify the time of fracture and correlate casewall expansion and velocity measurements. The analysis of the tungsten alloy had verified that if the material was capable of achieving at least a 25% strain to failure then the cylinder and rings would be viable controlled loading paths. However, fragments recovered from the explosively driven rings verified that the strain to failure was less than 14% and the triaxiality condition of uniaxial stress was not achieved by then. The data of this fragmentation under controlled loading conditions are to be used to determine coefficients for fracture-models and serve as benchmarks of relevant, dynamic fragmentation processes for future explosive/metal design opportunities.

Today Computational Fluid Dynamic (CFD) codes are widely used for industrial applications, mostly in the case of single phase flows in automotive or aircraft engineering, but multiphase flow modeling had gain an increasing importance in the last years. Safety analyses on nuclear power plants require reliable prediction on steam-water flows in case of different accident scenarios. This is particularly true for passive safety systems such as the GEKO component of the KERENA reactor. Here flashing may occur in the riser (Leyer and Wich, 2012). In such case, high gas volume fractions and the churn-turbulent flow regime may ensue. In the past, the codes for the prediction of churn-regime have not shown a very promising behavior. In this paper, a two-fluid multi-field hydrodynamic model has been developed based in the Euler-Euler framework. The main emphasis of this work has been on the modeling and applicability of various interfacial forces between dispersed gaseous phases and the continuous liquid, as well as bubble-bubble interactions, and the evolution of different bubble sizes in an adiabatic vertical pipe inside the churn-turbulent flow regime. All the expected mechanistic models that intervene in this flow pattern have been taken into account including drag force, wall force, lift force, turbulent dispersion, and bubble induced turbulence. Bubble breakup and coalescence has been defined (Liao et al., 2011), and in order to design a polydispersed model related to reality, the inhomogeneous MUSIG approach (Krepper et al., 2008) has been used to defined an adequate number of bubble size fractions which are arranged into different groups with their own velocity field. Based on these models, a series of simulations were made on the framework of ANSYS CFX 14.0, and all of the calculations were further validated with experimental data extracted from the TOPFLOW facility at the Helmholtz-Zentrum Dresden-Rossendorf. Different water and gas flow rates were used inside the churn-turbulent flow regime, as well as for the transition from bubbly to churn flow. The calculated cross-section averaged bubble size distributions, gas velocities, and time averaged radial profile for the gas fraction have shown a promising agreement with the experimental data. Nevertheless there are also clear deviations which indicate shortcomings of the present modelling. In order to further improve the modeling of this flow regime, a discussion based on the results will be used to shown a series of limitations of the actual modeling and possible solutions to be implemented in future works.
