Vortex Motion in a Stratified Medium

Abstract

A comprehensive computer code has been developed through the use of the governing equations of motion and the Boussinesq hypothesis and the rise of a vortex pair in a linearly density stratified medium has been calculated through the use of the Boit-Savart law and a finite difference scheme. The results have shown tha the code is capable of predicting the behavior of the vortices and the propagation of the internal waves resulting from the vortex motion. The reasons for the finite rise of the vortices in a stratified medium is clearly explained in terms of the counter-rotating vortices induced by the stratification. Keywords: Theses; Trailing vortices; Stratification.
