Research Abstract |
The experimental observation for 3-D reconstructed images confirmed that a vortex ring with appropriate swirl is insensitive to disturbances since the swirling flow preserves its ring structure. However, the characteristic fluid discharging from a vortex ring with swirl referred to as "peeling off' appears and its circulation decreases. The mechanism generating the "peeling off' is revealed numerically. The features of fluid transportation by means of vortex rings with swirl are reported. Furthermore, in order to put a vortex ring with swirl into practical use, it is generated from the nozzle attached with curved deflecting blades and its feature is investigated.
