Abstract:

The paper presents a large-eddy simulation of the flow over a sharp trailing edge. To minimize the computational effort inflow conditions for fully turbulent compressible boundary layers are developed. The LES findings show good agreement with other numerical and experimental data. For the prediction of the trailing-edge noise, acoustic perturbation equations are derived, which are excited by sources determined from results of a compressible flow simulation. Results of acoustic fields are presented for a model problem.
