A revised edition of the industry classic, this third edition shows how the field of heat transfer has grown and prospered over the last two decades. Readers will find this edition more accessible, while not sacrificing its thorough treatment of the most up-to-date information on current research and applications in the field. Features include: * Updated and expanded coverage of convection in porous media, focusing on microscale heat exchangers and optimization of flow configurations* Emphasis on original and effective methods such as scale analysis, heatlines for visualization, intersection of asymptotes for optimization, and constructal theory for thermofluid design* A readable text for students, in the tradition of the bestselling First Edition* New problems and examples taken from real-world practice and heat exchanger design* An accompanying solutions manual
