Abstract:
ABSTRACT Background of the study In 1978, kangaroo mother care (KMC) was proposed as a caring alternative for low birth weight infants. The method of skin to skin contact has shown physiologic, cognitive and emotional gains for preterm infant, however, kangaroo mother care has not been studied adequately in term newborns. The present study reporting early outcomes of comparing the kangaroo mother care to radiant warmer care. Objectives of the study: • To assess the neurobehavioral response of the newborn during radiant warmer care (RWC) and kangaroo mother care • The effect of radiant warmer care and kangaroo mother care on neurobehavioral response of the newborn. Methods A quasi-experimental post-test design was used in this study to compare the effect of kangaroo mother care and radiant warmer care on neurobehavioral response of term newborn. A total of 40 subjects who met the inclusion criteria were randomized—20 to KMC and 20 to RWC by simple random sampling technique. The data was collected by using the following tools: 1. Observational check list 2. Modified Brazelton Behavioral Assessment Scale. Results Both study groups were similar regarding all physiologic state variables. There is a slight difference in the behavioral state, the mean behavioral response scores of the RWC and KMC were 5.6500 and 5.9500 respectively, and the mean difference was 0.300. Interpretation and conclusion: The findings of the study showed that kangaroo mother care seems to influence state organization and physiologic state regulation of the newborn infant shortly after birth.

Abstract:
Radiant warmers are widely used in hospital neonatal care departments. Particular requirements for the basic safety and essential performance of infant radiant warmers are regulated by EN 60601-2-21:2009 + A1:2016. This standard doesn’t include the maximal air flow value over the infant bed while the standard 60601-2-19:2009 describes the maximal air flow values for incubators. This study shows fluctuation of the air flow over the infant bed and it leads to think, that a more preventive care of infants ambient is needed in the system. Authors have investigated the impact of air barriers on direct air flow value. Studies show that barriers can significantly decrease air flow over infant’s bed and potentially lower infant’s t heat losses by convection on infant bed.

Abstract:
An optimal thermal environment is regarded as a priority in the medical care of newborn infants (neonatology). Survival of each neonate (newborn infant) depends on the ability to regulate its temperature. Preterm and small neonates often cannot respond to the environmental temperature changes. For this reason, maintenance of neonates bodies within a narrow temperature range is essential for their survival and growth. However, there is one major concern when using radiant warmers, namely the neonates often become severely dehydrated when nursed in these devices. For this reason, the major objective of this thesis is to find a solution to this difficulty. In order to achieve this goal, numerical techniques including Computational Fluid Dynamics and conjugate heat transfer were employed. Mathematical mod- els applied to living organisms can provide a better understanding of the thermal processes occurring i~side a human body, together with their interactions with the surrounding environment. Therefore, in this thesis we focus on developing a model of a neonate under a radiant warmer that incorporates both heat and mass transfer processes in order to provide a better understanding of how a radiative heat source interacts with a neonate. The numerical models were prepared in ANSYS FLUENT and ANSYS CFX commercial softwares. The flow was assumed to be turbulent, and radiation cal- culations were performed as they are a crucial part of this analysis. Moreover, a semi-analytical ray tracking method was developed for the purpose of validating the numerical results. A good general agreement was observed when comparing the ray tracking results with the numerical ones. Next, a heat generation within the newborn was considered, and the numerical data was validated against the analytical calculations, and this comparison showed a good agreement of the results obtained using these two different techniques. Finally, several modifications to the geometry and operation of the radiant warmer are introduced in order to assist with the difficulty of high temperature gradients being obtained on the skin of the newborns nursed under the radiant warmer. It was found that the proposed modifications reduce the large temperature differences on the skin of the newborn. A more uniform temperature field on the skin will result in decreasing the evaporative loss. The proposed modifications in- clude to different approaches. Namely, the first solution, being a high conductivity blanket, can be easily implemented by the staff of the hospital. The second solution introduces modifications to the design of the radiant warmer, and it could be of interest to the producer of the device. Therefore, the main goal of this project, namely to find a solution to newborns becoming dehydrated when nursed under radiant warmers, has been successfully achieved.

Abstract:
Thermoregulation is considered a top priority in neonatology due to the fact that relative to adults, neonates have a morphological susceptibility to excessive heat exchange with the environment, and exhibit limited physiological/behavioural responses to thermal strain. Consequently, the environmental conditions in which they are nursed must be tightly regulated to maintain body temperature stable. Neonatal intensive care units (NICU) use radiant warmers (RW) to thermally manage many newborns. However, recent evidence suggests that RW induce intermittent bouts of thermal strain that could adversely affect patients. This warrants further investigation of neonatal heat balance and the pertinent factors affecting it. Conducting an exhaustive audit of heat exchanges affecting the body during standard care under a RW could yield important information that would lead to the improvement of clinical practice in NICUs. The present thesis focuses on neonatal thermoregulatory responses, various body heat exchange mechanisms and processes during standard care under RW.

Abstract:
Nel 2010 sono nati circa 15 milioni di bambini prematuri. Poiché i neonati prematuri hanno un sistema termoregolatore immaturo, essi hanno difficoltà a mantenere la temperatura del nucleo corporeo ad un livello costante. In questo lavoro è stato presentato un modello matematico multi-nodo del sistema termoregolatore del neonato. Successivamente sono stati presentati i metodi di terapia intensiva neonatale e le innovazioni nelle incubatrici e nei riscaldatori radianti. Infine, poiché c’è un alto tasso di mortalità infantile nei paesi in via di sviluppo ci si è concentrati sull’incubatrice Grashof. L’incubatrice Grashof è un dispositivo chiuso progettato in Indonesia che utilizza principalmente la convezione naturale per scaldare il bambino. In questo lavoro ne è stato presentato il modello e due principali modifiche. La prima consiste nell’aggiunta di un sistema di riscaldamento alternativo da utilizzare in caso di blackout. La seconda modifica consiste nell’aumentare la cabina per ospitare all’interno due gemelli.

Abstract:
A climatology of thermodynamic phase of precipitating cloud is presented derived from global—land and ocean—, retrievals from Cloudsat, CALIPSO, and Moderate Resolution Imaging Spectroradiometer. Like precipitation rate, precipitation frequency is dominated by warm rain, defined as rain produced via the liquid phase only, over the tropical oceans outside the Intertropical Convergence Zone and by cold rain, produced via the ice phase, over the midlatitude oceans and continents. Warm rain is very infrequent over the continents, with significant warm rain found only in onshore flow in the tropics, and over India, China, and Indochina. Comparison of the properties of precipitating and nonprecipitating warm clouds shows that the scarcity of warm rain over land can be explained by smaller effective radii in continental clouds that delay the onset of precipitation. The results highlight the importance of ice-phase processes for the global hydrological cycle and may lead to an improved parameterization of precipitation in general circulation models.

Abstract:
Urban space is an element not only traffic, habitat and work, but also recreation relationship and especially in the Mediterranean and warmer climates. A man tool to interact with their environment. But due to the increase in temperatures caused, among other reasons, by climate change and the decline of vegetation in the city, public spaces have become less comfortable places. This gradual decline of urban comfort has led to the start of several studies aimed at providing solutions to this situation that directly affects the quality of urban life people. In particular it has been found that vegetation is an excellent tool when it comes to sun protection. However, in studies of urban green so far been made, the representative value of vegetation determines regardless of the tree structure or density, characteristics that inevitably condition the behavior of each species. Nor it has quantified the contribution of the tree with respect to thermal comfort, therefore this thesis is inserted into this line of research. The main objective of this paper is to know of qualitative and quantitative effect of the foliage of a tree species in the thermal comfort in urban micro climate. The methodology is based on in situ measurements and model calculations, and has been applied to two climates (Mediterranean and humid warm). This research aims to provide parameters to analyze and quantify the structural, morphological and luxuriance of tree species for urban use, to thereby identify their contributions to urban thermal comfort features. The thesis is broken down into six chapters that explain the process followed this investigation. The research part of the analysis of the tree structure, explaining the contribution of each of its parts on comfort and improving the urban environment. In the first part, the characteristics that define the urban space conceptually, thermal comfort and vegetation are evaluated. Thus, the variables that mainly influence the micro climate urban are determined. The second part, the study methodology of the variables of the tree structure is exposed, allowing its characterization according to the luxuriance based on a calculation method and photographic enabling this classification into five categories. This methodology was applied for measurements in situ in Barcelona (Spain). The third part presents the implementation of the methodology designed three case studies in Barcelona with three different degrees luxuriance. So that the comparison of the effects produced by the luxuriance of the radiant temperature and solar radiation and its impact on thermal comfort is allowed. The fourth part, explains the application of the methodology in two different urban scenarios: a street and a square, to evaluate the effect of tree species on thermal comfort in relation to the urban morphology. In the fifth, the methodology is extrapolated to another climate, in this case, the hot and humid in the city of Santo Domingo (Dominican Republic). To this in situ of several tree species measurements they were performed. the exportability of the methodology is found, to various climatic conditions, urban typology and tree species. Finally, in the sixth, the conclusions of the research results and their interpretation are broken. It also stands as a final result a technical sheets of tree species, which are presented as a tool contribute to determining the suitability of species in urban design to improve thermal comfort and joy of urban space.
El espacio urbano es un elemento no sólo de tránsito, hábitat y trabajo, sino también de relación y de recreación especialmente en los climas mediterráneos y cálidos. Una herramienta del hombre para interactuar con su entorno. Pero, debido al incremento en las temperaturas provocado, entre otras razones, por el cambio climático y el decrecimiento de la vegetación en la ciudad, los espacios públicos se han convertido en lugares menos confortables. Esta disminución gradual del confort urbano ha motivado el inicio de diversos estudios cuyo objetivo es proveer soluciones frente a esta situación que afecta directamente a la calidad de vida urbana las personas. De forma particular se ha comprobado que la vegetación es una excelente herramienta en lo que refiere a la protección solar. Sin embargo, en los estudios sobre verde urbano que hasta ahora se han realizado, el valor representativo de la vegetación de determina sin tener en cuenta la estructura del árbol ni su densidad, características que inevitablemente condicionan el comportamiento de cada especie. Tampoco se ha cuantificado las aportaciones del árbol respecto al confort térmico, por ello la presente tesis se inserta dentro de esta línea de investigación. El presente trabajo tiene objetivo principal conocer de forma cualitativa y cuantitativa el efecto de la frondosidad de una especie arbórea en el confort térmico en el micro clima urbano. La metodología se basa en mediciones in situ y modelo de cálculo, y ha sido aplicada a dos climas (Mediterráneo y Cálido húmedo). Esta investigación busca aportar parámetros para analizar y cuantificar las características estructurales, morfológicas y de frondosidad de las especies arbóreas de uso urbano, para de esta forma identificar sus aportes al confort térmico urbano. La tesis se desglosa en seis capítulos que permiten explicar el proceso que ha seguido la presente investigación. La investigación parte del análisis de la estructura del árbol, explicando la aportación de cada una de sus partes en el confort y la mejora del ambiente urbano. En la primera parte, se evalúan las características que definen conceptualmente el espacio urbano, el confort térmico y la vegetación. De esta forma, se determinan las variables que principalmente influyen en el micro clima urbano. La segunda parte, se expone la metodología de estudio de las variables de la estructura del árbol, permitiendo su caracterización en función de la frondosidad con base en un método de cálculo y fotográfico que permite la clasificación de esta en cinco categorías. Esta metodología se aplico para las mediciones in situ en Barcelona (España). La tercera parte, expone la implementación de la metodología diseñada a tres casos de estudio en Barcelona, con tres grados frondosidad distinta. De forma que se permite la comparación de los efectos producidos por la frondosidad sobre la temperatura radiante y en la radiación solar, así como su incidencia en el confort térmico. La cuarta parte, explica la aplicación de la metodología en dos escenarios urbanos distintos: una calle y una plaza, para evaluar el efecto de las especies arbóreas en el confort térmico en relación a la morfología urbana. En la quinta parte, se extrapola la metodología a otro clima, en este caso, el cálido húmedo en la ciudad de Santo Domingo (República Dominicana). Para ello se realizaron mediciones in situ de varias especies arbóreas. Se constata la exportabilidad de la metodología, a diversas condiciones climáticas, tipología urbana y especies arbóreas. Finalmente, en la sexta parte, se desglosan las conclusiones obtenidas en los resultados de la investigación y su interpretación. También se presenta como resultado final unas fichas técnicas de las especies arbóreas, que se presentan como herramienta coadyuvan a la hora de determinar la idoneidad de las especies en el diseño urbano para mejorar el confort térmico y gozo del espacio urbano.

Abstract:
IN HIS SEMI-AUTOBIOGRAPHICAL Orange County: A Personal History, Gustavo Arellano describes a surrealist dream of return migration to his ancestral village of El Cargadero, deep in the heart of north-central México. “A couple of months before finishing this book,” Arellano writes, “I experienced the most vivid dream: I won a contest in which the main prize was the ability to fly” (2008: 25). After crisscrossing disparate geographies, from South East Asia to Eastern Europe, Gustavo decided to descend on El Cargadero, arriving in the late afternoon, when “the sun bathes everything in a soft, radiant glow.” Gustavo’s dream depicts the village quite accurately, verging on the utopian before taking a surrealist turn: “El Cargadero sits on the slope of a mountain, so rays either enveloped houses or cast them in shadows.” Hovering above, Gustavo tried to eavesdrop on conversations, “but all I heard was the laughs of contentment,” he writes. Once he landed on terra firma, “Streetlights flickered on, lending a beautiful shine to the village,” and people greeted him warmly....

Abstract:
This chapter offers a biographical sketch of Rashi. There are numerous folk legends about Rashi's birth, especially the miracles wrought for his mother during her pregnancy, and about his father and his father's journeys outside France and meetings with various sages, including Maimonides. None of these legends is reliably documented, however, and nothing can be gleaned from them about the events of Rashi's life. Ultimately, they reflect the cultural world of Jewish society in the late Middle Ages—a time that saw the composition, in Jewish circles as in Christian, of numerous hagiographical works recounting the miracles performed for holy men. Rashi is renowned throughout the Jewish world not only for his wide-ranging literary productivity but also for his unique character. Five qualities stand out in his warm and radiant personality: humility and natural simplicity, pursuit of truth, concern for human dignity, great confidence in his own abilities, and a sense of mission as a community leader. These qualities are evident in his actions, his relations with other people, his ties to his students, his world-view, his scorn for arrogance, his love of peace, his literary output, and even in his writing style. The chapter then considers Rashi's status and fame.

Abstract:
Then in the distance they could see part of the exterior of the mosque of al-Husayn. In the center was an expansive window decorated with arabesques … With joy singing in her breast, she asked: ‘Our master al-Husayn?’ He confirmed her guess. Her pace quickened for the first time since she left the house. She began to compare what she saw with the picture created by her imagination and based on what she had seen from her home of mosques like Qalawun and Barquq.

Abstract:
The chapter is devoted to the design and performance of adsorptive chillers. Basic types of design and operating principle of adsorptive chillers were analyzed. Advantages and disadvantages performance of one-, two-, three-, and four-bed solar power adsorptive chillers are compared. Performance of adsorptive refrigerators based on composite adsorbents was studied. The correlation between the adsorbent composition and the coefficient of energy performance of the adsorptive chiler was revealed. An optimal composition of adsorbent 'silica gel – sodium sulphate' is stated to be of 20% silica gel and 80% sodium sulphate. The maximal values of the coefficient of performance of cycle of studied solar adsorptive chiller about of 1.14 are stated for composites containing about 20 wt. % silica gel and 80 wt% sodium sulphate. As a consequence of decreasing of adsorbent mass, the coefficient of performance is shown to increase when sodium sulphate content in the composite increased. Regeneration process parameters of the composite were shown to strongly affect on the coefficient of performance of the adsorptive chiller. The growth of the coefficient of performance is stated to result from decreasing the difference between adsorbent temperature and regeneration temperature from 85 to 55°C. The basic factors affecting the net coefficient of energy performance of the adsorptive solar refrigerator were stated daily solar radiant flux alongside with composition of the adsorbent and difference between adsorbent temperature and temperature regeneration. Net coefficients of performance of solar adsorptive refrigerator based on composite ‘silica gel – sodium sulphate' were stated to change from 0.25 to 0.34 during operating period. Utilization of the adsorption heat is suggested to warm the heat carrier which applied to heat adsorbent during regeneration. The ways to improve the design and performance of adsorptive solar chillers are suggested. The first one involves the introduction of solar collectors made of cellular polycarbonate plastics in the design of adsorptive solar chiller. Instantaneous efficiency coefficient were calculated as special thermal performance-solar radiant flux surface density ratio, optical efficiency factor is determined as special thermal performance-solar radiant flux surface density ratio at the equal temperatures of heat transfer medium and environment, reduced heat loss factor being calculated as the product of solar collector efficiency factor and net heat loss coefficient. The environmental test of developed collectors PSK-AV2-3, PSK-AV1-2, PSK-AV2-1, PSK-VS1-2, PSK-VS2-2, PSK-VS2-3, PSK-ST10-PW were conducted. The correlation of their results with laboratory tests when the thermohydraulic stand applied is shown. Relative accuracy of laboratory and environment tests was shown to be not exceeding 5 – 7%. The optical efficiency factor and the coefficient of thermal losses of polymeric solar collectors were determined. On the basis of the dependencies of the efficiency of the solar collectors vs. the reduced temperature, optimal designs of the polymeric solar collectors for the adsorption chilling solar systems are determined to be depended on the temperature of the regeneration temperature of the sorbents. As the temperatures of the regeneration of composite adsorbent ranged from 50ºС to 60ºС, appliance of the collectors PSK-AV2-1, PSK-CT10-PW occur to be expedient, and PSK-AB2-3, PSK-VS2-3, PSK-AB1-2, PSK-VS2-2, and PSK-VS1-2 are revealed to be more efficient when regeneration temperatures increased over 80 ºС. Thermotechnical characteristics of designed polymeric solar collectors are shown to surpass conventional metal and vacuum collectors. The perspectives of polymeric solar collectors in the design of adsorptive chilling solar plants were shown. Another way to improve the performance of adsorptive solar chillers concerns with equipping it with a photosensitive element and an electric drive, which will allow changing the angle of slope of the adsorber to the horizon depending on the intensity of the solar radiation. The chapter can be useful for design the efficient adsorptive chilling plants.

Abstract:
Experimental data taken from gas turbine combustors indicate that the flow exiting the combustor can contain both circumferential and radial temperature gradients. A significant amount of research recently has been devoted to studying turbine flows with inlet temperature gradients, but no total pressure gradients. Less attention has been given to flows containing both temperature and total pressure gradients at the inlet. The significance of the total pressure gradients is that the secondary flows and the temperature redistribution process in the vane blade row can be significantly altered. Experimental data previously obtained in a single-stage turbine with inlet total temperature and total pressure gradients indicated a redistribution of the warmer fluid to the pressure surface of the airfoils, and a severe underturning of the flow at the exit of the stage. In a concurrent numerical simulation, a steady, inviscid, three-dimensional flow analysis was able to capture the redistribution process, but not the exit flow angle distribution. In the current research program, a series of unsteady two- and three-dimensional Navier-Stokes simulations have been performed to study the redistribution of the radial temperature profile in the turbine stage. The three-dimensional analysis predicts both the temperature redistribution and the flow underturning observed in the experiments.

Abstract:
Abstract This paper utilizes numerical modeling to address the effects of two parameters on natural draft cooling tower performance, namely the radial hot water distribution and flue gas injection. Predictions show that cold water temperature leaving the tower can be slightly decreased by increasing the weighting of the radial hot water distribution towards the tower periphery. The injection of scrubbed flue gas into the tower chimney can have either a positive or a negative effect on tower cooling performance, depending on the temperature of the flue gas relative to the temperature of moist air in the chimney. The temperature of the scrubbed flue gas is the primary variable affecting cooling tower performance, associated with flue gas injection. This paper investigates using the radial distribution of hot water to optimize the tower cooling performance when injecting scrubbed flue gas into the chimney, both for conditions when the flue gas is warmer and cooler than the temperature of moist air in the chimney. Predictions with no flue gas injection show that optimizing hot water distribution produced 0.4 °C reduction in cooled water temperature. With relatively cold (32.2 °C) and relatively hot (65.6 °C) flue gas injection, optimizing hot water distribution produced slightly more than 0.2 °C reduction in cooled water temperature.

Abstract:
In this work, human transient thermal responses and comfort are studied in non-uniform radiant heating and convective heating environments. The focus was on a change from walking activity of human in outdoor cold environment at high clothing insulation to warm indoor environment at sedentary activity level associated with lower clothing insulation. A transient multi-segmented bioheat model sensitive to radiant asymmetry is used to compare how fast the human body approaches steady state thermal conditions in both radiative and convective warm environments. A space thermal model is integrated with the bioheat model to predict the transient changes in skin and core temperature of a person subject to change in metabolic rate and clothing insulation when entering conditioned indoor space. It was found that overall thermal comfort and neutrality were reached in 6.2 minutes in the radiative environment compared to 9.24 minutes in convective environment. The local thermal comfort of various body segments differed in their response to the convective system where it took more than 19 minutes for extremities to reach local comfort unlike the radiative system where thermal comfort was attained within 7 minutes.

Full text
Abstract:
In this paper, a hydrodynamically coupled flexible disk rotating in a thin housing is mathematically modeled and an attempt is made to explain the jump instability phenomenon that occurs when the disk rotation speed is varied slightly. The disk is assumed to have an initial warped profile due to slight imperfections in the manufacturing process. After non-dimensionalization of the participating variables, a hybrid formulation is carried out. Radial flows above and below the disk are taken into consideration. The deflection and pressure equations form a coupled system, and a solution is attempted using the shooting method. The deflections obtained are plotted to obtain the deflected disk profile and appropriate conclusions are drawn.

Abstract:
Characteristics of thermal-hydraulic phenomena in the steam injector were examined. In experiments, a water jet from a nozzle of 5 mm diameter flowed into the condensing test section pipe concentrically. The inner diameter of the condensing section was 7, 10, or 20 mm and the length was 105 mm. Steam flowed into the peripheral space between the water jet and the inner wall of the test section and condensed on the ware jet surface. The radial and the axial distributions of velocity and temperature of the water jet were measured. Analyses by using the STAR-CD code were also performed. The temperature measured in the central portion of the water jet was higher than the predicted assuming the ordinary turbulent flow in a pipe. The temperature measured in the peripheral region was lower than the predicted. The radial temperature distribution measured was flatter than the predicted. When the steam condensation rate was large, the measured radial velocity distribution in the water jet was flatter than the predicted. In the case that the steam velocity was quite high, the velocity measured in the peripheral region was higher than that in the center portion. These results implied that the steam condensing on the water jet brought momentum in the water jet to result in more effective radial transport of heat and momentum. The STAR-CD code analyses to allow the interface between the wall that simulated the steam flow part and the water flow that stood for the water jet to move, i.e. creating momentum in-flux at the water jet interface, provided better results to support the experimental results. To increase the interfacial friction had a minor effect on the radial velocity distribution in the tested range.

Abstract:
The preliminary findings of an exploratory study conducted on a novel Oxyfuel Combustion Turbine Cycle (OCTC) using ASPEN PLUS for a range of 40% to 90% CO2 capture are presented. Starting from a GE Energy IGCC, the OCTC retains the Gasifier with a Radiant Cooler-only section and the Warm-Gas-Clean Up (WGCU) section with the desulfurization process eliminated for a combined carbon and sulfur co-sequestration approach. The conventional gas turbine combined cycle is also removed. With no integration between the Air Separation Unit (ASU) and the modified oxyfuel combustion turbine, the High Pressure (HP) ASU is replaced by a Low pressure (LP) ASU. The added attributes of this novel coal-based power system configuration are (1) the Vapor Absorption Refrigeration System (VARS), (2) the associated water production in the VARS evaporator, (3) the recirculation of combustor flue gas for lower NOx emissions and additional power production, as well as (4) an original concept of carbon dioxide compression as proposed by SouthWest Research Institute (SwRI) and Dresser Rand (D-R). Assuming a reasonable Coefficient of Performance (COP) for the VARS, the overall process efficiency results (about 35% HHV) were equivalent or even better when compared with studies of current simulated IGCC systems with CO2 capture. Once an optimum scheme has been finalized in future activities, an economic analysis would be conducted. The combined performance and economic results could then be compared with alternate advanced coal based power systems.

Abstract:
Abstract Multi-droplet impact on a thin liquid film covering a heated wall is numerically studied using a three-dimensional model with an implement of a random disturbance subjected to Gaussian distribution. The model can effectively simulate the splashing process after droplets impingement. Results show that simultaneous impact lowers splashing threshold due to cracking of central liquid sheet, while successive impact results in higher splashing threshold for the trailing droplet than the leading one due to radial flow inside the residual film. Single-phase heat transfer coefficient in the impinged region is remarkably higher than the undisturbed film region, caused by flow enhanced convective heat transfer. A heat transfer blind spot situated under the central liquid sheet in simultaneous impact is identified, at which relatively high local temperature is observed and heat is more difficult to be rejected due to flow stagnation there. Cooling of the heated wall in successive impact is mainly achieved by contacting of the trailing droplet with the heated wall, rather than mixing of cold droplets and warm film. This study discusses the effects of Weber number, wall heat flux and droplets horizontal/vertical interval on the heat transfer coefficient.
