This book is primarily a second level undergraduate text on fluid mechanics and will be useful for graduate courses in viscous flow as well. It emphasizes mathematical formulation of fluid mechanics problems and strategies available for solving them. With rapid advances being made in defence, environment and energy sectors, an analytical background in fluid mechanics has presently become a necessity. This book attempt at bridging the gap between basic principles and the training needed for complex engineering applications. The material covered should be of use to mechanical, chemical, aerospace and civil engineering disciplines. It contains major chapters on derivation of Navier-Stokes equations, exact solutions, potential theory, boundary-layer theory and turbulent flows. Shorter chapters on hydrodynamic stability and compressible flow are included. An introduction to numerical methods of boundary-layer equations and a review of experimental techniques are also covered. All chapters contain worked out examples, followed by a large collection of unsolved problems.
The style of presentation is engrossing since new concepts are introduced systematically and the reader is led to analyze challenging applications. Taken together, the text and the problems are intended to enable engineers to take up quickly the analysis of practical problems. The book has been widely used since its publication. The authors, their colleagues and students have made important suggestions for improvement of the book. The authors have taken this opportunity to correct typographical errors and introduce new material as well as problems. Specifically, the note on Bessel functions in Chapter 3 and the appendix on higher order boundary-layer theory in Chapter 5 contribute to making the book that well rounded. Additional problems help in better assimilation of the text material it is hoped that the readers find the revised edition useful.
