Stratified Flow Structure near the Horizontal Wedge

Abstract

In this work we studied the structure and dynamics of a two-dimensional flow of a continuously stratified fluid near a horizontal wedge using numerical methods. A mathematical model and a method of numerical implementation were developed. This allows for the simultaneous study of all the elements of multiscale stratified flows without additional hypotheses and connections. The numerical solution is implemented in the OpenFOAM open source package. The calculations were performed in the parallel mode with the use of computing resources of the UniHUB web-laboratory. The laws governing the flow formation are analyzed and the physical mechanisms that are responsible for the vortex formation in areas with high density gradients near the edges of the streamlined wedge are determined.
