Abstract

Problem of excitation of oscillations in boundary layer (BL) by a streamwise acoustic wave at Mach number M = 2.0 is considered. It was found that the ratio of amplitudes of mass flux perturbations inside BL and at its outer edge can reach significant values. Conclusion about existence of critical values of Reynolds number and an angle of orientation of acoustic wave, at which efficiency of excitation is highest, is confirmed. An approximate method for computation of disturbance level inside BL is offered. Interpretation of experimental data about supersonic BL receptivity is given.
