Noise pollution around airports, trains, and industries increasingly attracts environmental concern and regulation. Designers and researchers have intensified the use of large-eddy simulation (LES) for noise reduced industrial design and acoustical research. This 2007 book, written by 30 experts, presents the theoretical background of acoustics and of LES, followed by details about numerical methods, e.g. discretization schemes, boundary conditions, coupling aspects. Industrially relevant, hybrid RANS/LES techniques for acoustic source predictions are presented in detail. Many applications...

This unique book gives a general unified presentation of the use of the multiscale/multiresolution approaches in the field of turbulence. The coverage ranges from statistical models developed for engineering purposes to multiresolution algorithms for the direct computation of turbulence. It provides the only available up-to-date reviews dealing with the latest and most advanced turbulence models (including LES, VLES, hybrid RANS/LES, DES) and numerical strategies.The book aims at providing the reader with a comprehensive description of modern strategies for turbulent flow simulation, ranging...

L'ouvrage presente la technique de simulation des grandes echelles. Les bases mathematiques et les hypotheses physiques employees sont rappelees. Les concepts de modelisation structurelle et de modelisation fonctionnelle sont introduits, et servent a etablir une liste exhaustive, unique a ce jour, des modeles sous-maille existants. Outre la description de ces modeles, le lecteur trouvera des elements theoriques et des details pratiques concernant leur mise en oeuvre.

This book summarizes the most recent theoretical, computational and experimental results dealing with homogeneous turbulence dynamics. A large class of flows is covered: flows governed by anisotropic production mechanisms (e.g. shear flows) and flows without production but dominated by waves (e.g. homogeneous rotating or stratified turbulence). Compressible turbulent flows are also considered. In each case, main trends are illustrated using computational and experimental results, while both linear and nonlinear theories and closures are discussed. Details about linear theories (e.g. Rapid...

Computational resources have developed to the level that, for the first time, it is becoming possible to apply large-eddy simulation (LES) to turbulent flow problems of realistic complexity. Many examples can be found in technology and in a variety of natural flows.

The Turbulence and Interactions 2006 (TI2006) conference was held on the island of Porquerolles, France, May 29-June 2, 2006. The scientific sponsors of the conference were Association Francaise de Mecanique, CD-adapco, DGA Ecole Polytechnique Federale de Lausanne (EPFL), ERCOFTAC: European Research Community on Flow, Turbulence and Combustion, FLUENT, The French Ministery of Foreign Affairs, Laboratoire de Modelisation en Mecanique, Paris 6, ONERA. The conference was a unique event. Never before have so many organisations concerned with turbulence works come together in one conference. As...

The Turbulence and Interactions 2009 (TI2009) conference was held in Saint- Luce on the island of La Martinique, France, on May 31-June 5, 2009. The sci- tific sponsors of the conference were DGA Ecole Polytechnique Federale de Lausanne (EPFL), ERCOFTAC: European Research Community on Flow, Turbulence and Combustion, Institut Jean Le Rond d Alembert, Paris, ONERA. This second TI conference was very successful as it attracted 65 researchers from 17 countries. The magnificent venue and the beautiful weather helped the participants to discuss freely and casually, share ideas and projects, and...

Computational resources have developed to the level that it is becoming possible to apply large-eddy simulation (LES) to turbulent flow problems of realistic complexity. This book is the first fully dedicated collection on quality and reliability of LES.

Turbulent ?ows are ubiquitous in most application ?elds, ranging from - gineering to earth sciences and even life sciences. Therefore, simulation of turbulent ?ows has become a key tool in both fundamental and applied - search. The complexity of Navier Stokes turbulence, which is illustrated by the fact that the number of degrees of freedom of turbulence grows faster 11/4 thanO(Re ), where Re denotes the Reynolds number, renders the Direct Numerical Simulation (DNS) of turbulence inapplicable to most ?ows of - terest. To alleviate this problem, truncated solutions in both frequency and...
