The book entitled ¿MHD Heat / Mass Transport in Fluid Flow¿ is the result of many years of facilitating, researching, and teaching in the field of Computational Fluid Dynamics. This book places a clear emphasis on the applications of various effects of thermophoresis in flow models based on rigorous and current research. To describe and explain the research methodology concepts on various flow model, this book uses realistic examples to help students get inside what research work is really like. In addition to examples, we have provided mathematical concepts of flow models so that students can learn the way of solving techniques uniquely. Different types of flow models will help students / scholars to distinguish between analytical and numerical solutions in practices, as well as help them to identify the practices they wish to adopt to improve their knowledge.
