LARGE-EDDY SIMULATION FOR ACOUSTICS
Noise pollution around airports, trains, and industries increasingly attracts environmental con-
cern 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 thirty
experts, presents the theoretical background of acoustics and LES followed by details about nu-
merical methods such as discretization schemes, boundary conditions, and coupling aspects. In-
dustrially relevant, hybrid Reynolds-averaged Navier–Stokes/LES techniques for acoustic source
predictions are discussed in detail. Many applications are featured ranging from simple geome-
tries for mixing layers and jet flows plex wing and car geometries. Selected applications
include recent scientific investigations at industrial and university research institutions. Presently
perfect solution methodologies that address all relevant applications do not exist; however, the
book presents a state-of-the-art collection of methods, tools, and evaluation methodologies. The
advantages and weaknesses of both mercial and research methodologies are carefully
presented.
Claus Wagner received his . in Fluid Dynamics in 1995 at the Technical University of
Munich, Germany. He is Honorary Professor for Industrial Aerodynamics, Ilmenau University
of Technology, Germany. Since 1998, he has been a scientist in and head of the Section of Nu-
merical Simulations for Technical Flows of the Institute for Aerodynamics and Flow Technology,
German Aerospace Center, G¨ottingen, Germany. Dr. Wagner’s research includes experimental
investigations of the resonant control of nonlinear dynamic systems, theoretical and numerical
