Abstract
The problem is considered on a periodical of time motion of a viscous liquid bordering on a solid body and a gas. The liquid is affected by oscillatory influences which have no predominant direction in space. The new hydro-mechanical effect is revealed which consists in that the free parts of the hydro-mechanical system - liquid layers - perform unidirectional stationary rotational motion with the background of oscillations.
