| Vortex rings are very stable structures that can be generated when the fluid is transiently released from the nozzle. High stability of such structures allows transporting momentum for large distances. This interesting feature opened an extensive debate on that phenomenon in academic forum. In turn, a number of research works can be found on such issues as generation, motion and decay of vortex rings. Not much attention has been put, however, on examining how the geometry of the vortex ring generator may influence on properties of generated structures and this work is aimed at filling this gap. |
