INITIAL STAGE OF AN OBLIQUE IMPACT OF A LARGE SOLID SPHERE ON A WATER LAYER
An oblique impact of a spherical segment with a curvature radius of 106.5 mm onto a water layer 20 mm thick is studied up to the instant of the body–liquid contact. The range of the impact angle with respect t...

Experimental study of disk impact onto shallow water
A problem of the impact of circular disks with a flat, convex, or concave onto a finite-depth fluid layer is experimentally studied. The influence of the small curvature of the lower surface of the body on the...

Effect of generator shape on the structure of internal wave beams in a uniformly stratified fluid
The generation of internal waves by vibrating cylinders with cross sections of various shapes is studied experimentally. It is shown that at large distances from the generator, the profile of the perturbation ...

Effect of the nonmonotonic temperature dependence of water density on free convection from a linear heat source
This paper presents the results of experimental studies of free convection from a heated wire in water for the two cases where the water temperature is higher or lower than the temperature at which water has m...

Finite-amplitude solitary waves in a two-layer fluid
Second-mode nonlinear internal waves at a thin interface between homogeneous layers of immiscible fluids of different densities have been studied theoretically and experimentally. A mathematical model is propo...
