Abstract

In this work we present a Large Eddy Simulation of an aero-acoustic test case consisting of a plate located in the turbulent wake of a circular cylinder. This configuration is very attractive for the validation of low Mach number aero-acoustic codes and coupling techniques, since a high sound pressure level is present at a very low Mach number and also because its simple geometry. Further it seems to be an interesting test case for future works if besides aero-acoustics also fluid induced vibrations are of interest.

In order to identify the involved noise generation mechanisms, mean pressure fluctuations as well as frequency spectra are investigated. The numerically obtained frequencies are compared to experimental data.
