RÉSUMÉ

Numerical simulation of the receptivity of a two-dimensional boundary layer on a flat plate to the low-intensity disturbances in the form of a local periodic energy supply located above and inside the boundary layer is carried out at the free-stream Mach number M = 6. Heat spots interact with the boundary layer, which result in acoustic disturbances and generate unstable waves. It is shown that maximum amplitude of these waves is reached when the center of the energy supply is located near the upper edge of the boundary layer.
