摘要: The present paper reports an experimental study of the development plane monochromatic waves in boundary layer on a flat plate at Mach number M = 2.0. wave characteristics are obtained. Three-dimensional disturbances with angle vector to flow χ 50–70° found be most unstable. It is shown that disturbances, consisting vortical and compressible modes, engendered supersonic by local source artificial disturbances. increase bluntness leading edge stabilizes three-dimensional mode.
