Regularization of Barotropic Gravity Waves in a Two-Layer Fluid

Аннотация

The results of the experiments on studying the effect of the upper layer of a viscous fluid on the process of breaking and regularization of the standing gravity Faraday wave on the free surface of a two-layer fluid in a rectangular vessel are discussed. The situation considered is compared with the case of standing gravity wave on the free surface of homogeneous fluids whose viscosity differs significantly, namely, water and seed oil. The effect of increase in the upper layer thickness on the limit steepness of the regular wave and its dissipative properties is considered. The crucial role of emulsion formed under intense oscillations of immiscible fluids for suppression of the standing wave breaking mechanism is demonstrated.
