… Flow separation, induced by strong shock waves interacting with a boundary layer, is
harmful to many aerospace applications. An established technique to control the flow is by
using air-jet vortex generators (AJVGs). Here, streamwise vortices are generated by
injecting steady air-jets into the crossflow, which redistribute the boundary-layer momentum,
thereby improving their resistance to separation. The effectiveness of AJVGs depends on a
number of parameters. An encouraging parameter is the jet-orifice shape, which affects the …
