Abstract
Shock-induced separation is a common phenomenon in aero-space transportation applications which can result in strong detrimental effects. A promising method of passive control to mitigate this effect is the application of air-jet vortex generators (AJVGs). In the present study, we focus on the influence of jet spacing and the injection pressure in an AJVG array on the control efficiency of a \(24^\circ \) compression ramp induced shock-wave/boundary-layer interaction. Experiments were conducted at Mach 2.5 and oil-flow and focusing schlieren visualization were used to analyse the interaction region. The results indicate an appreciable amount of interaction between the jets produced the best control efficiency while a reduction in control efficiency was observed for both very strong and very weak interactions between the AJVG induced vortices.
