摘要：The penetration of a sonic or supersonic gaseous jet injected through abounding wall into a sonic or supersonic cross flow is controlled by modification of theapproach flow boundary layer. Penetration is increased when the separation pressure isreduced by disturbing the approach flow boundary layer. Both transpiration of smallamounts of gas into the boundary layer, and positioning a trip or blockage elementupstream of the injection station, will produce increased penetration.
