Abstract In this paper, the initial evolution of ring-like vortices which are found behind the MVG-controlled supersonic flow is studied. It is verified that the ring-like vortices can come from the upstream vortex structure and be generated by shear layer instability at the boundary of the momentum deficit as well. However, because of the inflow’s fully developed turbulent flow, the lower boundary layer underneath the ring-like vortex structure will influence the formation of the vortex rings a lot. Furthermore, it is also found that certain vortex structures in the lower boundary layer can be lifted up and become the ring-like vortex. The formation and development of the ring-like vortices is more complicated under the consideration of the influence of the fully developed turbulent inflow.
