Abstract
Suppression of shock wave/turbulent boundary layer(SW/TBL)interaction occurred inside a supersonic air-intake is important for ensuring and maintaining the aerodynamic performance. It is well known that boundary layer bleed is effective for the SW/TBL interactions and has been employed practically. However, in respect to bleed, there are some shortomings, for example, loss of mass flow rate. In this study, we focused on vortex generators (VGs) that are used as a control device for separation. We calculated a three dimensional SW/TBL interaction field by VGs and investigated the effect of VGs in such a flow field numerically. We researched several configurations of VGs, and found that the largest VGs, which is almost as high as boundary layer thickness, can suppress the SW/TBL interaction in the light of the flow distortion.
