A numerical study of two microramp geometries has been conducted to study their effectiveness in controlling swept shock wave–boundary-layer interactions. The planar shock wave is generated by placing a 20 deg sharp fin in a supersonic flow at Mach 4. The heights of microramps were varied as 30, 40, 50, 60, 70, and 90% of the boundary-layer thickness. The effect of microramp width and spacing is also studied. It is observed that boundary-layer separation is delayed significantly, downstream of the devices. Further, larger ramp heights were found to be more beneficial in delaying the separation.
