The suppression of large-scale vortex formations under gas-saturation conditions is detected on the basis of measurements of the pulsation component of the surface friction when an axisymmetric hot jet of a fluid impinges on an obstacle. The conditions for the resonant enhancement of coherent structures and the suppression of broad-band turbulence are determined for single-phase and gas-saturated impact jets. The evolution of various pulsation components in the gradient region of an impact jet is analyzed.
