Abstract The boundary value problem for a singularly perturbed system of two second-order ordinary differential equations with different powers of a small parameter at the second derivatives is considered without requiring the right-hand sides to be quasimonotonic. The specific feature of the problem is that one of the two equations of the degenerate system has a double root. It is proven that for

Experimental Study of Wind Interaction with a Wave Induced by a Wave Generator in a Direct Channel Moscow Univ. Phys. Bull. (IF 0.3) Pub Date : 2023-12-01
Abstract An experimental study has been conducted on the effect of wind blowing on a wave induced by a wave generator in a direct channel. It is shown that with a small wave steepness \(ak<0.1\) and wind speed \(W<2.3\) m/s, a drift current is generated on the water surface due to the action of viscous forces. A formula for calculating its velocity is proposed. It has been found that the phase velocity
