A compressible rescaling method is developed to generate time-dependent inflow conditions for boundary layer flows that provide inflow distributions for large eddy simulations of subsonic trailing-edge flow and supersonic compression-ramp flow. The comparison with analytical, experimental, and computational data shows the high quality of the new rescaling formulation. Based on the hybrid concept the large eddy simulation data is used to compute the sound field of the flow over a trailing edge of a flat plate via acoustic perturbation equations.
