This book was released on 2009-12-01 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentos de Balanços de Energia é um manual que aborda duma forma simples e pedagógica a realização de balanços energéticos em sistemas em estado estacionário. O manual cobre uma parte significativa dos programas das disciplinas de Análise de Sistemas Químicos e Biológicos e Termodinâmica, dos atuais Mestrados Integrados em Engenharia Química e Engenharia do Ambiente. O texto inicia-se com um conjunto fundamental de conceitos e definições que suportam a aplicação do princípio da conservação da energia, ou seja a realização de balanços energéticos. Em seguida apresenta-se a equação geral dum balanço de energia e aplica-se a sistemas particulares, que não envolvem reação química. O cálculo das entalpias é abordado com detalhe em processos a temperatura variável (e pressão constante), nos processos de mudança de fase e de mistura. A última parte debruça-se sobre balanços de entalpia em sistemas onde ocorre reação química, sendo dado particular relevo à definição dos estados de referência na determinação dos vários termos da equação do balanço. Ao longo do texto, é feita referência aos vários problemas que se encontram resolvidos na última secção e que têm como objetivo sedimentar a informação apresentada.

Download or read book Thermosyphons and Heat Pipes Theory and Applications written by Marcia Barbosa Henriques Mantelli and published by Springer Nature. This book was released on 2020-12-22 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about theories and applications of thermosyphons and heat pipes. It discusses the physical phenomena that drive the working principles of thermosyphons, heat pipes and related technologies. Many applications are discussed in this book, including: rationalizing energy use in industry, solar heating of houses, decrease of water consumption in cooling towers, improvement of the thermal performance of industrial and domestic ovens and driers and new devices for heating stored oil and gas in petrochemical plants. Besides, the book also presents heat pipe and thermosyphon technologies for the thermal management of electronic devices, from portable equipment to airplanes and satellites. The first part of the book explores the physical working principles of thermosyphons and heat pipes, by explaining current heat transfer and thermal resistance models. The author discusses the new heat pipe and thermosyphon technologies that have been developed in the last decade for solving a myriad of electronic, environment and industrial heat and thermal problems. The focus then shifts to the thermosyphon technology applications, and the models and simulations necessary for each application – including vehicles, domestic appliances, water conservation technologies and the thermal control of houses and other structures. Finally, the book looks at the new technologies for heat pipes (mini/micro) and similar devices (loop heat pipes), including new models for prediction of the thermal performance of porous media. This book inspires engineers to adopt innovative approaches to heat transfer problems in equipment and components by applying thermosyphon and heat pipe technologies. It is also of interest to researchers and academics working in the heat transfer field, and to students who wish to learn more about heat transfer devices.

Download or read book Computational Methods in Multiphase Flow IV written by A.A. Mammoli and published by WIT Press. This book was released on 2007-05-11 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid Dynamics is one of the most important topics of applied mathematics and physics. Together with complex flows and turbulence, multiphase flows remains one of the most challenging areas of computational mechanics, and even seemingly simple problems remain unsolved to date. Multiphase flows are found in all areas of technology, at all length scales and flow regimes. The fluids involved can be compressible or incompressible, linear or nonlinear. Because of the complexity of the problem, it is often essential to utilize advanced computational and experimental methods to solve the complex equations that describe them. Challenges in these simulations include nonlinear fluids, treating drop breakup and coalescence, characterizing phase structures, and many others.This volume brings together work presented at the Fourth International Conference on Computational and Experimental Methods in Multiphase and Complex Flows. Featured topics include: Suspensions; Bubble and Drop Dynamics; Flow in Porous Media; Interfaces; Turbulent Flow; Injectors and Nozzles; Particle Image Velocimetry; Macroscale Constitutive Models; Large Eddy Simulation; Finite Volumes; Interface Tracking Methods; Biological Flows; Environmental Multiphase Flow; Phase Changes and Stochastic Modelling.
