In this chapter, we propose a series of new discoveries from our high order LES, including the spiral point near the leading edge, the origin of the momentum loss, the vortex structure, the topology of the flow separation, and some conclusions of other physics in the flow. Although there are some studies of experiments and numerical simulations on fluid flow controlled by MVG recently, only two-dimensional flow information was provided and confirmed by those studies. The three dimensional flow field behind MVG is still unclear. To better understand the flow structure especially the vortex structure in the downstream of the MVG, the flow field around the MVG and surrounding areas has been investigated in details. In addition, the 3D shock wave structure in the flow field is also studied in this book.
