This article is devoted to the investigations of free surface flows excited by a partially submerged plate.Low-frequency oscillations of the plate lead to the formation on the liquid surface of two vortices on each side of the plate, in which a liquid move away from the surfaces of the plate. Under parametric excitation of transverse capillary waves in a thin layer of liquid wetting the surface of the plate, the direction of the vortex flow is reversed. High-frequency vibrations of the plate lead to the formation of secondary vortices on the liquid surface.
