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 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 are featured ranging from simple geometries for mixing layers and jet flows to complex wing and car geometries. Selected applications include recent scientific investigations at industrial and university research institutions. Presently one can't offer perfect solution methodologies that address all relevant applications, however the book presents a state of the art collection of methods, tools and evaluation methodologies. The advantages and weaknesses of both the commercial and the research methodologies are carefully presented.

Sagaut, Pierre
Prof. Pierre Sagaut received his DEA in Mechanics in 1991 and his PhD in Fluid Mechanics in 1995 at University Pierre et Marie Curie - Paris 6 (Paris, France). He used to work as a research engineer at ONERA (French National Aerospace Research Center) from 1995 to 2002. He has been a Professor in Mechanics at University Pierre et Marie Curie - Paris 6 since 2002. He is also part-time Professor at Ecole Polytechnique (France), and scientific consultant at ONERA, IFP and CERFACS (France). His main research interests are fluid mechanics, aeroacoustics, numerical simulation of turbulent flows (both Direct and Large-Eddy Simulation) and numerical methods. He is also involved in uncertainty modeling for CFD. He authored and co-authored more than 60 papers in peer-reviewed international journals and 130 proceeding papers. He is the author of several books dealing with turbulence modeling and simulation. He is member of several editorial boards: Theoretical and Computational Fluid Dynamics, Journal of Scientific Computing, Progress in CFD. He received three times the ONERA award for the best publication, and the John Green Prize (delivered by ICAS, 2002).
