Kurzfassung
Purpose of this investigation is the simulation of separated turbulent ramp flow as a simple generic model for re-entry vehicle flaps under threedimensional disturbances. Parametervariations of crossflow, disturbance intensity and wavelength of the disturbances are tested. Comparison with wind tunnel data from the Ludwieg tube facility in Göttingen (RWG) was used to validate the numerical code and getting a deeper insight into the flow topology. The dependence of the vortices from surface disturbances and a tendency to circular vortex shape at reattachment has been shown experimentally and numerically in good agreement. Finally a damping influence of crossflow in the separation region was investigated.
