| The results of the experimental investigations of the vortical structure (vortical ring) transformation in laminar shear stratified flow are presented. It is shown that the stratification action causes the decrease of the height of vortex ring lift when the ejection is executed in vertical direction across flow. It is found that the behaviour of vortex rings in shear flow substantially differ from the behaviour of the vortex rings in stationary fluid. It is demonstrated that two solitary waves traveling along the ring core are arosen. This leads to the scattering of the ring trajectories. |
