This well-known 2-volume textbook provides senior undergraduate and postgraduate engineers, scientists and applied mathematicians with the specific techniques, and the framework to develop skills in using the techniques in the various branches of computational fluid dynamics. Volume 1 systematically develops fundamental computational techniques, partial differential equations including convergence, stability and consistency and equation solution methods. A unified treatment of finite difference, finite element, finite volume and spectral methods, as alternative means of discretion, is emphasized. For the second edition the author also compiled a separately available manual of solutions to the many exercises to be found in the main text.
