This contribution presents a numerical study of jet noise installation effect for a generic configuration. The geometry definition consist of a single stream nozzle which is mounted closely under a NACA0012 wing. Such constellations produce significant interaction effects especially in terms of aeroacoustics. The applied methodology is a novel CAA approach which can be classified as a partly scale resolving simulation. In conclusion, the computed results are validated with measurements for a comparable constellation of a flat plate over a single stream nozzle with the same flow conditions. The validation of the CAA computation delivered a good agreement which indicates that all principal effects are numerically well reproduced.
