Experimental investigations of the influence of shear stratified flows on the development of vortical rings (Q2784950)

The results of experimental investigations of vortical ring transformation in laminar shear stratified flow are presented. It is shown that the stratification leads to decreasing height of the vortex ring lift when the ejection is executed in a vertical direction across flow. It is found that the behaviour of vortex rings in shear flow substantially differs from the behaviour of the vortex rings in stationary fluid. It is demonstrated that two solitary waves traveling along the ring core from the opposite direction appear as a result of shear. This leads to the scattering of ring trajectories.
