Heat and mass transfer can be encountered in many applications ranging from design and optimization of traditional engineering systems, such as heat exchangers, turbine, electronic cooling, heat pipes, and food processing equipment, to emerging technologies in sustainable energy, biological systems, security, information technology and nanotechnology. The purpose of this textbook is to present the subject of heat and mass transfer with a focus on the significant advances in the field in the last decade, while emphasizing the basic, fundamental principles. It provides advanced, relevant materials in heat and mass transfer in a single volume for undergraduate senior and graduate students instead of relying upon several books. Engineering students in a wide variety of engineering disciplines - from mechanical and chemical to biomedical and materials engineering - must master the principles of heat and mass transfer as an essential tool in analyzing and designing any system or systems wherein heat and mass are transferred. This textbook was developed to address that need, with a clear presentation of the fundamentals, ample problem sets to reinforce that knowledge, and tangible examples of how this knowledge is put to use in engineering design. Professional engineers, too, will find this book invaluable as reference for everything from traditional to emerging heat and mass transfer system.
