The book "Principles of Heat Transfer in Porous Media, Second Edition" by Massoud Kaviany is a comprehensive monograph that integrates theoretical and empirical treatments to provide a detailed understanding of heat transfer in porous media. The book is divided into two parts: Part I covers single-phase flows, and Part II addresses two-phase flows. Each part includes chapters on fluid mechanics, heat conduction, convection, radiation, mass transfer, and thermal nonequilibrium between phases. The book also discusses the complexities of two-phase flow, including hysteresis, liquid-vapor coexistence, and phase change processes. New sections and updated references have been added in the second edition to reflect recent advancements in the field, such as numerical results on dispersion in periodic structures and oscillating flows, and experimental and numerical data on radiative properties. The author acknowledges the contributions of students, collaborators, and sponsors who have supported his research in this area.The book "Principles of Heat Transfer in Porous Media, Second Edition" by Massoud Kaviany is a comprehensive monograph that integrates theoretical and empirical treatments to provide a detailed understanding of heat transfer in porous media.
