The book is the only one of its kind devoted entirely to the subject of Large Eddy Simulation. It presents a comprehensive account and a unified view of this young but very rich discipline. Concentrating on incompressible fluids, the book presents both the mathematical ideas and the applications with care. The second edition, a greatly enriched version motivated by the increasing interest in LES and new applications, offers two new chapters. One treats coupling of LES with multiresolution multidomain techniques and the other new hybrid approaches that relate LES to the statistical methods based on the Reynolds Averaged Navier-Stokes equations.

Klappentext

First concise textbook on Large-Eddy Simulation, a very important method in scientific computing and engineering

From the foreword to the third edition written by Charles Meneveau: "... this meticulously assembled and significantly enlarged description of the many aspects of LES will be a most welcome addition to the bookshelves of scientists and engineers in fluid mechanics, LES practitioners, and students of turbulence in general."
