This book entitled ¿Analytical / Numerical study of Magnetohydrodynamic Flows in Porous Mediä is followed by a presentation of an intuitive systematic problem-solving technique that can be used as a model in solving engineering problems. A distinctive feature of this book is its emphasis on the physical aspects of the subject matter in addition to mathematical representations and manipulations. The authors believe that the emphasis in research level should remain on developing a sense of underlying physical mechanisms and a mastery of solving practical problems that an academicians/engineers. The authors have found differential equations to be a never ending source of interesting and sometimes surprising, results and phenomena. We hope that users of this book, both scholars and Academicians, will share our enthusiasm for the subject. It is hoped that the mathematical solutions obtained in this book contribute not only to a better understanding of the problems they deal with, but also find significant applications in many engineering, industrial and environment processes and the acquired knowledge in this book can be used by designers to control MHD flow.
