Based on the OpenFOAM numerical simulation platform, the dynamic mesh technology and Detached-eddy simulation (DES) are used to study the flow field characteristics of corner shock wave boundary layer interactions (SWBLI) when the micro vortex generator (MVG) moves downstream at a certain speed. The inlet Mach number is 2.5, and the speed of the MVG moving downstream is 0 m / s, 10 m / s and 20 m / s. The results show that when MVG moves downstream, the high pressure area in SWBLI region will gradually weaken or even disappear. The boundary layer thickness of SWBLI will gradually decrease; this shows that dynamic MVG has a good control effect on SWBLI. As the movement speed increases, the control effect becomes more obvious. MVG controls SWBLI through the wave-system structure generated by MVG and the streamwise vortex pair of wakes.
