AB  - Shock-wave/boundary-layer interactions (SWBLIs) are complex flowfields commonly encountered in many high-speed aerospace applications. A strong shock wave imposes a large adverse pressure gradient and can lead to large-scale flow separation. The separated flow and the separation-inducing shock are highly unsteady, causing fluctuating pressure and thermal loads on the surface, inlet instabilities, et cetera; they are generally detrimental to the safe and reliable operation of the vehicle. Hence proper control of the flow is essential. In this thesis, separation control with air-jet vortex generators (AJVGs) is experimentally investigated. Various configurations of a single row of spanwise-inclined AJVGs at 45° are used to control a fully-separated 24° compression-ramp interaction. The results show clear evidence of streamwise vortices induced by the injected jets. Consequently, the 2D separation line of the baseline case is now corrugated. Effectively configured AJVGs can reduce separation length by nearly 25
