Zusammenfassung:The paper presents two and three-dimensional flow separation within a supersonic intake at Mach number 3. Unsteady behavior of a separation bubble at the wedge base in the intake was clarified by using a micro flow sensor which can detect flow reversal in a separated flow. Flow visualization is made by a vapor screen and oil-film techniques. The secondary flow on the side wall and cowl surface involves a large scale of vortices due to the interaction of the oblique shock wave with the turbulent boundary layer.
