Abstract

The paper presented the results on the generation and development of the wave train in spanwise modulated supersonic boundary layer at Mach 2 and 2.5, which obtained experimentally in the same conditions of controlled experiment. In experiments on the flat plate with roughness it was obtained that at the Mach number M = 2.5 both a subharmonic and fundamental wave packet develops almost linearly, whereas at the Mach number M = 2.0 there is competition between the two mechanisms of unstable waves interaction. It was obtained that in the boundary layer on swept wing the roughness presence can leads to the stabilization of the wave packet development at fundamental and subharmonic frequency in the downstream direction.
