Kurzfassung
An accurate description of the mean flow, the rms values, and spectral distributions of the seperated boundary layer fluctuating velocities plays an important role in predicting trailing edge far field noise. A possible method for describing the mean and rms quantities based on a modification of Coles' law of the wake and Prandtl's mixing length theory is presented. The model is validated against related experiments from literature and new measurements conducted at DLR Braunschweig. Additionally, a comparison between the von Kármán spectrum for isotropic turbulence and the measured spectra inside the seperated boundary layer is given. The results strongly suggest that the spectra as well as the mean and rms values of the seperated flow can be modeled with the proposed approaches.
