Computational Acoustics

The book presents a state-of-art overview of numerical schemes efficiently solving the acoustic conservation equations (unknowns are acoustic pressure and particle velocity) and the acoustic wave equation (pressure of acoustic potential formulation). Thereby, the different equations model both vibrational- and flow-induced sound generation and its propagation. Latest numerical schemes as higher order finite elements, non-conforming grid techniques, discontinuous Galerkin approaches and boundary element methods are discussed. Main applications will be towards aerospace, rail and automotive industry as well as medical engineering. The team of authors are able to address these topics from the engineering as well as numerical points of view.

Presents comprehensive physical / mathematical modelling of vibro- and aeroacoustics Applies state of the art of numerical methods (Finite Elements, Boundary Elements, Discontinuous Galerkin) Comprehensively discusses direct, iterative and multigrid solvers Discusses numerical simulations applied to industrial problems Includes supplementary material: sn.pub/extras
