The study presents the results of studying surface friction, gas concentration, and pressure pulsations in a turbulent boundary gas-saturated layer. To exert a favorable effect directly on the turbulent generation process in the near-wall boundary layer, it is this region that should be saturated with small gas bubbles with size of about the viscous sublayer thickness. In this case, the efficiency of gas saturation significantly increases. (13 refs.)
