Keywords: supersonic boundary layer instability, receptivity, oscillating Mach wave

The present paper describes our numerical study of supersonic boundary layer receptivity to Mach waves incident onto leading edge at freestream Mach number 2.2. We examine the external disturbance field around the leading edge in detail to clarify the formation of oscillating Stokes layer and its evolution into T-S wave.
