  In this paper, the implicitly implemented LES method and fifth order
bandwidth optimized WENO scheme are used to make comprehensive studies on the
separation topology of the MVG controlled flow at M=2.5 and Re{\theta}=5760.
Experiments are also made to verify the prediction of the computation. Analyses
are conducted on three categories of the topology: the surface separation,
cross-section separation and the three dimensional structure of the vortices. A
complete description about the separation topology and a series of new findings
are obtained. Among them, a pair of spiral point is first predicted by the
computation and verified by the experiment. A corresponding new vortex model
with 7 vortex tubes is presented also.
