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 are featured ranging from simple geometries for mixing layers and jet flows to complex wing and car geometries. Selected applications include scientific investigations at industrial and university research institutions.
- The book contains the knowledge of 30 internationally respected experts
- A variety of different applications are presented in the book ranging from simple geometries to complex wing or car geometries, which makes the book interesting for academic as well as for industrial research
- The book shows a collection of different methods, tools and evaluation methodologies and explains their individual advantages and weaknesses
Reviews & endorsements
Review of the hardback: 'I am certainly glad the authors took the trouble to support the task of compiling such a badly needed text, providing such an excellent up-to-date sound reference source.' Journal of Fluid Mechanics
Review of the hardback: '… a timely publication in addressing one of the important impacts of man-made machines … on the environment we all live in. … I would strongly recommend this book to graduate students, researchers, and practical engineers who are interested in the simulation of noise generated by turbulent flows with large separations. It serves as a worthwhile introduction, reference, or handbook to the field of computational aeroacoustics, with a list of over 900 papers cited.' Proceedings of the Institution of Mechanical Engineers
