Riassunto

In its third revised and extended edition the book offers an overview of the techniques used to solve problems in fluid mechanics on computers. The authors describe in detail the most often used techniques. Included are advanced techniques in computational fluid dynamics, such as direct and large-eddy simulation of turbulence. Moreover, a new section deals with grid quality and an extended description of discretization methods has also been included. Common roots and basic principles for many apparently different methods are explained. The book also contains a great deal of practical advice for code developers and users.

Recensione

"This book, primarily oriented towards industrial applications, intends to provide engineers with the necessary background to use and understand commercial fluid dynamics modeling codes or, alternatively, to develop their own. ... In summary, this text, which is commendable for its excellent plain English and pedagogic qualities, constitutes an excellent introduction to the world of computational fluid dynamics and will proudly find its place on the shelf besides more classical reference textbooks." --Michael Crucifix, Physicalia, Vol. 25 (2), 2003

"In reviewer s opinion, the book is a mixture of surveys and detailed discussions, the latter reflecting the experience of the authors. Thus the book is valuable for the beginners and also for the specialists." --Willi Schönauer, Zentralblatt MATH, Vol. 998, 2002
