Abstract

The mathematical model and the numerical implementation method permitting to study simultaneously all the elements of the internally multi-scale stratified flows are developed. For the first time, the induced diffusion flows on a fixed symmetrical wedge with the curved edges are calculated and visualized using the supercomputer systems. Influence both of the edge effects and the wedge lateral edge curvature upon the flow structure is shown. In a stably stratified environment, the integral force inducing self-motion of a free wedge along the neutral buoyancy horizon towards the top is formed by pressure deficit in the adjacent jet streams.
