说明：  Computational fluid dynamics has been a hot topic of research these last forty years, and several books have been published on this topics. This book concentrates on the numerical of Computational Fluid Mechanics, followed by some focus of new development of classical methods, and to the recent methods appearing in this field. The present volume presents in nine chapters a selection of some numerical methods used in computational fluid mechanics including: mathematical models in computational fluid mechanics, numerical methods in computational fluid mechanics, finite volume, finite difference, finite element, spectral methods, smoothed particle hydrodynamics methods, mixed-element-volume methods, free surface flow. The topics covered in this book are wide ranging and demonstrate the extensive use in computational fluid mechanics.
