Abstract A numerical study to evaluate the critical height of microvortex generators in controlling swept shock wave boundary layer interactions is carried out. The planar shock wave is generated by placing a 20° sharp fin in a supersonic flow at Mach 4. The ramp and thick vane microvortex generator geometries were considered. The device heights were varied from 30 to 90 % of the incoming boundary layer thickness. The efficacy of the devices was observed to increase with increasing device height up to a height of 70 % of the incoming boundary layer thickness beyond which no further improvement was achieved.
