Abstract
In the framework of the German research project FREQUENZ, a joint effort of industry, research establishment and universities has been undertaken to study the effect of design variations on aeroacoustics of a simplified high lift configuration. The flow past an airfoil with small trailing edge devices (MiniTED) was investigated numerically for the case of a generic landing configuration. Because of the turbulent and separated flow character behind the high lift device a hybrid RANS-LES approach was chosen to investigate the flow phenomena. Furthermore, the noise in the turbulent flow field was investigated by evaluating the pressure distribution. As a large measurement campaign has been undertaken within FREQUENZ, it is possible to validate the aerodynamic and the aeroacoustic results.
