The results presented here provide new insight into the flow behavior in the presence of streamwise vortices generated by the rods. The following conclusions can be drawn from the above described experimental investigations: - Streamwise vortices cause a pressure recovery improvement downstream of the shock wave, which show a tendency towards reduction of separation. - The vortices cause the entrainment of higher momentum fluid into the lowest strata of a boundary layer which counteracts separation and helps to reduce the height of the λ-foot. - The separation size is significantly reduced by streamwise vortices generated by the rods. - The flow pattern becomes asymmetric when the corotating streamwise vortices are introduced into the flow. - The streamwise vortices pass under the shock wave and the shock does not disintegrate the vortices. The streamwise vortices stretch downstream of the shock wave. - For the flow with vortex generator there is no continued separation in the spanwise direction and the vortices cut the separation on small, cell-like, 3D structure with a pitch corresponding to a VG sequence. - The rod vortex generator does not affect the flow unsteadiness in the interaction area; RMS and mean amplitude of shock oscillations are very similar to those in the reference flow.
