- Аннотация: An experimental study has been conducted on the effect of wind blowing on a wave induced bya wave generator in a direct channel. It is shown that with a small wave steepness ak < 0.1 and wind speedW < 2.3 m/s, a drift current is generated on the water surface due to the action of viscous forces. A formulafor calculating its velocity is proposed. It has been found that the phase velocity of the wave increases withthe emergence of drift current and can be calculated by the formula obtained for linear waves in a flow witha constant velocity shear. With an increase in wave steepness ak > 0.19 and wind speed W > 2.3 m/s, theformation of a vortex deforming the water surface over the wave crest was observed in the air flow over thewave crest. The vortex destroys the viscous layer, reducing the drift velocity. This also reduces the phasevelocity and the length of the wave. A mechanism explaining this process has been proposed.
