Heat and mass transfer are ubiquitous transport phenomena in many fields, from the natural environment and living organisms to the engineering process. This book focuses on the latest advances in applying fundamental heat and mass transfer theory and novel technologies for addressing a wide range of industrial problems of interest. This book will present readers with a recent analytical study, CFD modelling, and experimental investigations of heat and mass transfer topics associated with a variety of engineering disciplines including multiphase flow, nanofluids, porous media, battery thermal management, and engineering processes such as extractive distillation and arc welding. The book aims to provide new insights to understand the heat and mass transfer phenomena, serving as a platform for exchanging inspiring ideas and boosting further development of these disciplines.
