Abstract

The results of the measurements of the time-periodic controlled disturbances in an inhomogeneous flat-plate boundary layer are considered at Mach number 2.5. The disturbances were introduced using a high-frequency glow discharge. The electric power of the discharge has been constant chosen. The nonlinear downstream development of wave trains and a considerable effect of the unit Reynolds number on the nature of the disturbance interaction is found to exist under the experimental conditions. An analysis of the wave characteristics of the disturbances is carried out.
