Shock wave and turbulent boundary layer interaction in a double compression ramp

•An increase of Lc results in decreased spanwise width and increased spanwise coherency of these counter-rotating streamwise vortices.•Analysis of fluctuating wall pressure indicates that the low-frequency unsteadiness is strongly suppressed in the interaction region.•The main effect is observed in...
