In this chapter, a new mechanism of SBLI control by MVG is presented.
Traditionally, people consider the reduction of shock-induced separation is caused by
streamwise vortex which mixes the boundary layer flow and makes the velocity profile
to be more able to withstand the flow separation. The new mechanism shows the
spanwise vortex rings are critical which are quickly moving and fast rotating to destroy
or undermine the shock and ease up the shock-induced flow separation significantly.
Potentially, this study could contribute to some technology revolution in control of
SBLI, flow separation and interference reduction.
