N2 - The occurrence and development of hydrodynamic perturbations generated by low-frequency vibrations of a local section of a streamlined surface in a separated flow behind a rectangular ledge on a flat plate are investigated in the wind tunnel. The results were obtained by the hot-wire anemometry method at a low subsonic flow velocity. It is established that vibrations of the wall generate perturbations of the separation zone, which are streaky structures, and accompanying wave packets of oscillations. The separation of the laminar boundary layer promotes the growth of wave packets with subsequent turbulence of the wall flow.
