"Buoyancy-Induced Flows and Transport" by Benjamin Gebhart, Yogesh Jaluria, Roop L. Mahajan, and Bahgat Sammakia is a comprehensive and up-to-date textbook on natural convection heat transfer. The book successfully brings together current knowledge in a broad and diverse field, emphasizing physical mechanisms, general formulations, analysis, and results. It serves as both a reference and a graduate-level textbook for thermal sciences. The book is well-written, balanced in theory and experiment, and includes over 200 problems at the end of each chapter, focusing on applications. It cites over 2,000 references per chapter and includes a large number of recent references. The book covers a wide range of topics, including external vertical thermally-induced flows, vertical axisymmetric flows, combined mass and thermal transport, and turbulent free-boundary flows. It also includes chapters on instability, transition, turbulence, transport in enclosures, porous media, and non-Newtonian transport. The book relies on analytical techniques such as boundary layer approximation, similarity variables, and asymptotic methods. It also presents extensive experimental work with empirical correlations, tables, and photographs. However, the book has some shortcomings, such as long discussions or detailed mathematical analyses that obscure fundamentals, lack of clear discussion of mechanisms, and absence of concise derivations of equations with their limitations. The book mainly focuses on steady flows and provides too many versions of starting equations. References are often summarized without critical evaluation. Despite these shortcomings, the book is a useful reference for thermal laboratories."Buoyancy-Induced Flows and Transport" by Benjamin Gebhart, Yogesh Jaluria, Roop L.
