Three-dimensional characteristics of separation vortex generated by crossing shock/boundary layer interaction

AIP Advances
Three-dimensional shock/boundary layer interactions (SBLIs) in the hypersonic inlet generate the separation vortex, which affects the flow uniformity of the inlet and can even cause the inlet to unstart.
