Preface

This book aims at providing researchers and practitioners with a valuable compendium of the latest significant advances in the field of heat and mass transfer. The book covers a set of topics of particular interest ranging from heat transfer in power generation to heat and mass transfer in new and emerging technologies. The book comprises 19 chapters arranged in eight sections, which include: Introduction, Heat Transfer in Industrial Processes, Heat Transfer in Power Generation, Heat and Mass Transfer in New and Emerging Technologies, Multi-phase Flows and Phase Change, Thermodynamics and Thermophysical Properties, Mass Transfer Processes and Theoretical Approaches for Heat Transfer Problems. Several chapters within the book include theoretical and numerical modeling and simulation developments, which are increasingly contributing to the current state of the art in heat and mass transfer.

This book has been possible thanks to the outstanding contributions of many scientists, researchers, and engineers in the field of heat and mass transfer, and also the exceptional work of the professionals at IntechOpen. All contributions are sincerely acknowledged and truly appreciated..

I sincerely believe that the content of the book will be of interest to researchers, practitioners, and graduate students within the many disciplines and applications involved

and Mass Transfer - Advances

Heat and mass transfer is the core science for many industrial processes as well as technical and scientific devices. Automotive, aerospace, power generation (both by conventional fossil-based technologies and also by renewable energies), industrial equipment and rotating machinery, materials and chemical processing, and many other industries are involving heat and mass transfer processes.Consequently, both heat transfer and mass transfer are disciplines of the highest significance in technology and industry and obviously also in research and academia. As an example, over 10,000 journal publications are published every year with the latest

This book, titled *Heat and Mass Transfer: Advances in Science and Technology Applications*, intends to provide researchers and practitioners with a valuable compendium of significant advances in the field of heat and mass transfer, focusing both on the scientific and research fields and also on applications within industrial scenarios. There is a clear rationality in presenting both heat and mass transfer within a single book, as it must be considered that both processes are governed by very similar mathematical equations, particularly in the case of diffusion and convection (however, heat radiation is not having a similar process in mass transfer). The book includes 19 chapters, arranged in a set of 8 sections according to the logic and significance of its contents. The book comprises sections focused on industrial applications, such as heat transfer in industrial processes or heat transfer in power generation. An extensive collection of chapters dealing with heat and mass transfer process relevant to industry is included, such as steam boilers, heat exchanger optimization, cryogenics, concentrated solar power (CSP), additive manufacturing processes for metals, supercritical CO2 precipitation, falling film evaporators, or non-Newtonian fluids in mixing vessels. Other sections such as thermodynamics or theoretical approaches for heat transfer problems are involving chapters more focused on scientific aspects, with topics covering bio-convective linear stability, diffusion of Fe2B layers on steels, Rayleigh convection in viscoelastic fluids, irreversible thermodynamics, or calculation of thermal properties, among others. The book also contains sections covering heat and mass transfer in new and emerging technologies, multiphase flows and phase change, and mass transfer

Experimental setups and results are covered within the book, but as modeling and simulation techniques are increasingly contributing to the development of
