O.G.Stetsenko Steady motion of vortex near rigid wall in stratified medium |
Applied hydromechanics, Vol. 10 (82) ¹ 4, (2008) |
| The article described a solution to the problem on forsed stationary motion of a two-dimensional point vortex near a solid horizontal border in a semiunrestricted linear stratified fluid. A solution was obteined, which corresponds to the movement of a pair of vortices in a non-restricted medium, similar to that in a uniform medium. The performed calculatios shoved that the cinematic pattern of the fluid motion in the vortex proximity changes insignificantly for low stratification. However, stratification results in the hydrodynamic drag force which has a tendency to quickly increase as stratification grows. |
