SPECTRAL FINITE ELEMENTS FOR COMPUTATIONAL AEROACOUSTICS USING ACOUSTIC PERTURBATION EQUATIONS

Andreas Hüppe, Manfred Kaltenbacher

Open publisher page 29 citations

Abstract

This paper addresses the application of the spectral finite element (FE) method to problems in the field of computational aeroacoustics (CAA). We apply a mixed finite element approximation to the acoustic perturbation equations, in which the flow induced sound is modeled by assessing the impact of a mean flow field on the acoustic wave propagation. We show the properties of the approximation by numerical benchmarks and an application to the CAA problem of sound generated by an airfoil.
