Computational Fluid Dynamics and Heat Transfer is meant for undergraduate and postgraduate students, research scholars and teaching community of Aerospace Engineering and Mechanical Engineering. This book explains the fundamentals of heat transfer and focuses mainly on finite difference method, which is one of the computational methods used to solve engineering problems. The major strength of the book is that it covers one-dimensional, two-dimensional steady and transient conduction and convection problems in detail. This book will definitely be highly useful for those who wish to understand the finite difference method for solving fluid flow and heat transfer problems for their research and industrial applications.
