Texto completoO objetivo do presente trabalho é determinar os coeficientes de perda de carga e transferência de calor, normalmente aplicados nos cálculos analíticos de design térmico de hidrogeradores, obtido pela aplicação de cálculo numérico (Computacional Fluid Dynamics - CFD) e validado por resultados experimentais e medições de campo. O objeto de estudo é limitado à região mais importante do sistema de ventilação (os dutos de ar de arrefecimento do núcleo do estator) para obter resultados numéricos dos coeficientes de transferência de calor e de perda de carga, que são impactados principalmente pela entrada de dutos de ar. Os cálculos numéricos consideraram escoamentos tridimensionais, em regime permanente, incompressíveis e turbulentos; e foram baseados no método dos volumes finitos. Os cálculos de escoamento turbulento foram realizados com procedimentos baseados em equações médias (RANS), utilizando o modelo k-omega SST (Shear-Stress Transport) como modelo de turbulência. Métricas de qualidade de malha foram monitoradas e as incertezas devido à erros de discretização foram avaliadas por meio de um estudo de independência de malha e aplicação de um procedimento de estimativa de incertezas com base na extrapolação de Richardson. A validação do método numérico desenvolvido pelo presente trabalho (especificamente para simular o comportamento dinâmico do escoamento e obter numericamente o coeficiente de perda de carga do escoamento ao entrar no duto de ar e atravessar o núcleo do estator de um hidrogerador) é realizada comparando os resultados numéricos com dados experimentais publicados por Wustmann (2005). Os dados experimentais foram obtidos como referência por um teste de modelo. A comparação entre os resultados numéricos e experimentais mostra que a diferença da perda de carga para números de Reynolds mais elevados do que 5000 é no máximo de 2%, enquanto que para números de Reynolds inferiores, a diferença aumenta significativamente e atinge 10%. A hipótese mais razoável para a maior discrepância para número de Reynolds menores é a possível influência de instabilidades do escoamento no experimento, fazendo com que o regime seja não-permanente. Conclui-se que o método numérico proposto é validado para a região superior do intervalo analisado. Além da validação pelo ensaio de modelo, medições de campo foram executadas, a fim de confirmar os resultados numéricos. As medições de perda de carga no núcleo do estator de um hidrogerador real era um desafio. No entanto, apesar de todas as dificuldades e consideráveis incertezas da medição campo, o comportamento das curvas de tendência ficou alinhado com resultados numéricos. Finalmente, uma série de cálculos numéricos, variando parâmetros geométricos do design da entrada do duto de ar e dados operacionais, foram executados a fim de se obter curvas de tendência para coeficientes de perda de carga (resultados deste trabalho) a serem aplicadas diretamente à rotinas de cálculos analíticos de sistemas completos de ventilação de hidrogeradores. Paralelamente à isso, o cálculo térmico numérico foi executado na simulação do protótipo, a fim de se definir o coeficiente de transferência de calor por convecção.

Texto completoThe development of a dynamic computational model capable of predicting, with the requisite design certainty, the transient thermal response of jet vane thrust control systems has been undertaken. The modeling and simulation procedures utilized are based on the concept that the thermal processes associated with jet vane operation can be put into a transfer function form commonly found in the discipline of automatic controls. Well established system identification methods are employed to formulate and verify the relationships between the various gains and frequencies of the transfer function model and experimental data provided by Naval Weapons Center, China Lake.

"Characterization of dynamic thermal control schemes and heat transfer pathways for incorporating variable emissivity electrochromic materials into a space suit heat rejection system". Thesis, University of Colorado at Boulder, 2016. http://pqdtopen.proquest.com/#viewpdf?dispub=10108691.
Texto completoThe feasibility of conducting long duration human spaceflight missions is largely dependent on the provision of consumables such as oxygen, water, and food. In addition to meeting crew metabolic needs, water sublimation has long served as the primary heat rejection mechanism in space suits during extravehicular activity (EVA). During a single eight hour EVA, approximately 3.6 kg (8 lbm) of water is lost from the current suit. Reducing the amount of expended water during EVA is a long standing goal of space suit life support systems designers; but to date, no alternate thermal control mechanism has demonstrated the ability to completely eliminate the loss. One proposed concept is to convert the majority of a space suit’s surface area into a radiator such that the local environment can be used as a radiative thermal sink for rejecting heat without mass loss. Due to natural variations in both internal (metabolic) loads and external (environmental) sink temperatures, radiative transport must be actively modulated in order to maintain an acceptable thermal balance. Here, variable emissivity electrochromic devices are examined as the primary mechanism for enabling variable heat rejection. This dissertation focuses on theoretical and empirical evaluations performed to determine the feasibility of using a full suit, variable emissivity radiator architecture for space suit thermal control. Operational envelopes are described that show where a given environment and/or metabolic load combination may or may not be supported by the evaluated thermal architecture. Key integration considerations and guidelines include determining allowable thermal environments, defining skin-to-radiator heat transfer properties, and evaluating required electrochromic performance properties. Analysis also considered the impacts of dynamic environmental changes and the architecture’s extensibility to EVA on the Martian surface. At the conclusion of this work, the full suit, variable emissivity radiator architecture is considered to be at a technology readiness level of 3/4, indicating that analytical proof-of-concept and component level validation in a laboratory environment have been completed. While this is not a numeric increase from previous investigations, these contributions are a significant iteration within those levels. These results improve the understanding of the capabilities provided by the full suit, variable emissivity architecture.

The purpose of this thesis is to present on the development and results of the cooling system logic tree and model developed as part of the Pipeline Research Council International, Inc (PRCI) funded project at the Kansas State National Gas Machinery Laboratory. PRCI noticed that many of the legacy engines utilized in the natural gas transmission industry were plagued by cooling system problems. As such, a need existed to better understand the heat transfer mechanisms from the combusting gases to the cooling water, and then from the cooling water to the environment. To meet this need, a logic tree was developed to provide guidance on how to balance and identify problems within the cooling system and schedule appropriate maintenance. Utilizing information taken from OEM operating guides, a cooling system model was developed to supplement the logic tree in providing further guidance and understanding of cooling system operation. The cooling system model calculates the heat loads experienced within the engine cooling system, the pressures within the system, and the temperatures exiting the cooling equipment. The cooling system engineering model was developed based upon the fluid dynamics, thermodynamics, and heat transfer experienced by the coolant within the system. The inputs of the model are familiar to the operating companies and include the characteristics of the engine and coolant piping system, coolant chemistry, and engine oil system characteristics. Included in the model are the various components that collectively comprise the engine cooling system, including the water cooling pump, aftercooler, surge tank, fin-fan units, and oil cooler. The results of the Excel-based model were then compared to available field data to determine the validity of the model. The cooling system model was then used to conduct a parametric investigation of various operating conditions including part vs. full load and engine speed, turbocharger performance, and changes in ambient conditions. The results of this parametric investigation are summarized as charts and tables that are presented as part of this thesis.

Texto completoThe objective of this study was to increase the output current and power in a piezoelectric transformer (PT) based DC/DC converter by adding a cooling system. It is known that the output current of PT is limited by temperature build-up because of losses especially when driving at high vibration velocity. Excessive temperature rise will decrease the quality factor Q of piezoelectric component during the operational process. Simultaneously the vibration energy cannot be increased even if under higher excitation voltage. Although connecting different inductive circuits at the PT secondary terminal can increase the output current, the root cause of temperature build-up problem is not solved.This dissertation presents the heat transfer technology to deal with the temperature build-up problem. With the heat transfer technology, the threshold vibration velocity of PT can be increased and thus the output current and output power (almost three times).Furthermore, a comparison between heat transfer technology and current-doubler rectifier applied to the piezoelectric transformer based DC/DC converter was also studied. The advantages and disadvantages of the proposed technique were investigated. A theoretical-phenomenological model was developed to explain the relationship between the losses and the temperature rise. It will be shown that the vibration velocity as well as the heat generation increases the losses. In our design, the maximum output current capacity can increase 100% when the operating condition of PT temperature is kept below 55°C. The study comprises of a theoretical part and experimental proof-of-concept demonstration of the proposed design method

Texto completoIn the future, new challenges will occur during the product development in the vehicular industry when emission legislations getting tighter. This will also affect the truck cooling system and therefore increase needs for analysing the system at different levels of the product development. Volvo 3P wishes for these reasons to examine the possibility to use AMESim as a future 1D analysis tool. This tool can be used as a complement to existing analysis methods at Volvo 3P. It should be possible to simulate pressure, flow and heat transfer both steady state and transient.
In this thesis work a cooling system of a FH31 MD13 520hp truck with an engine driven coolant pump is studied. Further a model of the cooling system is built in AMESim together with necessary auxiliary system such as oil circuits. The model is validated using experimental data that have been produced by Volvo 3P at the Gothenburg facility.
The results from validation and other simulations show that the model gives a good picture of the cooling system. It also gives information about pressure, flow and heat transfer in steady state conditions. Further a design modification is done, showing how a change affects the flow in the cooling system.
The conclusion is that a truck cooling system can be built and simulated in AMESim. Further, it shows that AMESim meets the requirements Volvo 3P in Gothenburg has set up for the future 1D analysis tool and thereby AMESim is a good complement to the already existing analysis method.
