This book reveals the latest research outputs in computational fluid dynamics. It contains selected chapters on fluid flow problems authored by international researchers. It highlights the current trends in the modelling and simulation aspects of fluid dynamics. Even though modelling and simulations in fluid dynamics are now considered mainstream in analysing fluid flows, heat and mass transfer problems, researchers are still exploring various numerical approaches and recipes to achieve better accuracy and efficiency for challenging applications in biomedical, aerospace, renewable energy and other industrial engineering applications. The book aims to bring many of the diverse modelling and simulation tools in one place and to advance existing progress in the emerging sciences of fluid dynamics. It summarizes current mathematical and physical modelling approaches as well as computational techniques applicable to fluid dynamics. The book would be of special interest to physicists and researchers in several fields related to computational, applied sciences and engineering.
