Computational Analysis of Transport Phenomena and Performance of PEMFC presents a practical guide to the mathematical modeling and simulation of PEMFCs for all transport processes of mass, momentum, energy, ions, and electrons. Tackling one of the most important aspects of next-generation PEMFC technologies, the book brings together the state-of-the-art to model and simulate phenomena and processes at various scales, including catalyst layers, electrodes, membranes, and bipolar plates of PEMFC unit cells and stacks. Chapters introduce PEM fuel cells and explain the underlying electrochemical and thermodynamic concepts involved, present a detailed breakdown of the governing equations for overall mass, momentum, and energy conservation, charge (ions and electrons) conservation, water generation and its transport, heat generation, and heat transfer and cooling methods, offer an in-depth analysis of the various single and multi-dimensional modelling approaches and considerations, including lattice Boltzmann approach, artificial neural networks, exergy and energy analysis, estimation of fuel and oxidant consumption, the differences between cell-scale, stack-scale, and system-scale approaches, and more.

Augmentation of heat transfer is important in energy conservation and developing sustainable energy systems. This book provides the science necessary to understand the basics of heat transfer augmentation in single-phase engineering systems. It considers theory and practice including computational and experimental procedures, evaluation techniques for performance, and new trends. Several applications of augmentation methods like surface modification, introduction of vortex flow and impinging jets, opportunities of ultrasound and magnetic fields, pulsatile flows, heat exchangers, and nanofluids are provided. Details of basic phenomena and mechanisms are highlighted. Key features:Provides the fundamental science needed to understand and further develop heat transfer augmentation for future energy systemsGive examples of how ultrasound and magnetic fields, vortex flow, impinging jets, surface modification and nanofluids can augment heat transferConsiders basic issues of computational and experimental methods for analysis, design, and evaluation of efficient and sustainable heat transferIt is an ideal reference text for graduate students and academic researchers working in the fields of mechanical, aerospace, industrial, manufacturing, and chemical engineering.

Heat Transfer in Aerospace Applications is the first book to provide an overall description of various heat transfer issues of relevance for aerospace applications. The book contains chapters relating to convection cooling, heat pipes, ablation, heat transfer at high velocity, low pressure and microgravity, aircraft heat exchangers, fuel cells, and cryogenic cooling systems. Chapters specific to low density heat transfer (4) and microgravity heat transfer (9) are newer subjects which have not been previously covered. The book takes a basic engineering approach by including correlations and examples that an engineer needs during the initial phases of vehicle design or to quickly analyze and solve a specific problem. Designed for mechanical, chemical, and aerospace engineers in research institutes, companies, and consulting firms, this book is an invaluable resource for the latest on aerospace heat transfer engineering and research.

This Brief addresses the phenomena of heat transfer enhancement. A companion edition in the SpringerBrief Subseries on Thermal Engineering and Applied Science to three other monographs including “Critical Heat Flux in Flow Boiling in Microchannels,” this volume is idea for professionals, researchers, and graduate students concerned with electronic cooling.
