Abstract
In this paper, the monotone integrated large-eddy simulation method and fifth-order weighted essentially nonoscillatory scheme are used to study the effects of the declining angles of the trailing edge of a microramp vortex generator atM 2:5 and Re 1440. Two angles are selected for study: 70 and 45 . Results show that the smaller declining angle at 45 can make the vortices closer to the wall, which is favorable to flow control. However, the improvement in the quality of the boundary layer is less obvious.
