Abstract
A problem is formulated and solved on the motion of a viscous liquid in a gravity field. The liquid is in contact with curvilinear walls and is exposed by oscillatory influences which have no predominant direction in space. The problem formulation includes the equation of Navier-Stokes, the equation of continuity, and the conditions at the solid boundaries of the liquid. In particular, the new hydro-mechanical effect is revealed which consists in that the liquid behaves paradoxically that is performs a steady “down up” motion (at a background of oscillations).
