The book introduces study of heat and mass transfer from the view point of transport phenomena. The book aims at developing the subject from basic levels but includes topics of contemporary interest. This approach allows a student to learn basic material and also have an idea of advanced applications. The special feature of the book is in solving problems, and offering explanations both from a mathematical view point and rationalization from a physical basis. Another important aspect of the book is the emphasis placed on scaling and understanding dimensionless groups. With the belief that students should be enabled to work on applications, chapters on computational fluid dynamics and turbulence are included in the book. These aspects distinguish this book from other books on transport phenomena.
