Estimation of water-surface deformation by vortices in a viscous horizontally decelerating air flow

Abstract

The maximum height of a disturbance on the water surface, which occurs when a spatial (non-point) vortex departs from a viscous layer of a horizontal air flow that decelerates in the direction of motion, is estimated. The dependence of the initial disturbance parameters on the air flow speed over the water surface is derived. It is shown that the height of the disturbance increases and its width decreases with an increase in the air flow speed. The suggested model is verified experimentally.
