CRC Press, Taylor & Francis Group, 2008. 344 p. 130 Illustrations. — ISBN 978‑0‑8493‑7262‑9 (hardback: alk. paper).Features Develops computational and experimental methods to identify regions of high entropy production and associated energy losses Provides comprehensive coverage (related to entropy and the Second Law) of laser-based methods, numerical methods in CFD, microfluidics and and turbulent flows Includes applications to design problems in emerging technologies, such as micro-systems and multiphase flows Integrates the design methodology with tools developed in Computational Fluid DynamicsSummary From engineering fluid mechanics to power systems, information coding theory and other fields, entropy is key to maximizing performance in engineering systems. It serves a vital role in achieving the upper limits of efficiency of industrial processes and quality of manufactured products. Entropy based design (EBD) can shed new light on various flow processes, ranging from optimized flow configurations in an aircraft engine to highly ordered crystal structures in a turbine blade.Entropy Based Design of Fluid Engineering Systems provides an overview of EBD as an emerging technology with applications to aerospace, microfluidics, heat transfer, and other disciplines. The text extends past analytical methods of Entropy Generation Minimization to numerical simulations involving more complex configurations and experimental measurement techniques.The book begins with an extensive development of basic concepts, including the mathematical properties of entropy and exergy, as well as statistical and numerical formulations of the second law. It then goes on to describe topics related to incompressible flows and the Second Law in microfluidic systems. The authors develop computational and experimental methods for identifying problem regions within a system through the local rates of entropy production. With these techniques, designers can use EBD to focus on particular regions where design modifications can be made to improve system performance. Numerous case studies illustrate the concepts in each chapter, and cover an array of applications including supersonic flows, condensation and turbulence.A one-of-a-kind reference, Entropy Based Design of Fluid Engineering Systems outlines new advances showing how local irreversibilities can be detected in complex configurations so that engineering devices can be re-designed locally to improve overall performance.Table of ContentsIntroduction Introduction Governing Equations of Fluid Flow and Heat Transfer Mathematical Properties of Entropy and Exergy Governing Equations of Entropy and the Second Law Formulation of Entropy Production and Exergy DestructionStatistical and Numerical Formulations of the Second Law Introduction Conservation Laws as Moments of the Boltzmann Equation Extended Probability Distributions Selected Multivariate Probability Distribution Functions Concave Entropy Functions Statistical Formulation of the Second Law Numerical Formulation of the Second LawPredicted Irreversibilities of Incompressible Flows Introduction Entropy Transport Equation for Incompressible Flows Formulation of Loss Coefficients with Entropy Production Upper Entropy Bounds in Closed Systems Case Study of Automotive Fuel Cell Design Case Study of Fluid Machinery DesignMeasured Irreversibilities of Incompressible Flows Introduction Experimental Techniques of Irreversibility Measurement Case Study of Magnetic Stirring Tank Design Case Study of Natural Convection in Cavities Measurement UncertaintiesEntropy Production in Microfluidic Systems Introduction Pressure-Driven Flow in Microchannels Applied Electric Field in Microchannels Micropatterned Surfaces with Open MicrochannelsNumerical Error Indicators and the Second Law Introduction Discretization Errors of Numerical Convection Schemes Physical Plausibility of Numerical Results Entropy Difference in Residual Error IndicatorsNumerical Stability and the Second Law Introduction Stability Norms Entropy Stability of Finite Difference Schemes Stability of Shock Capturing MethodsEntropy Transport with Phase Change Heat Transfer Introduction Entropy Transport Equations for Solidification and Melting Heat and Entropy Analogies in Phase Change Processes Numerical Stability of Phase Change Computations Thermal Control of Phase Change with Inverse Methods Entropy Production with Film CondensationEntropy Production in Turbulent Flows Introduction Reynolds Averaged Entropy Transport Equations Eddy Viscosity Models of Mean Entropy Production Turbulence Modeling with the Second Law
