چکیده

This work summarises the impact of Coriolis forces on the formation of a vortex ring. The initial formation of the ring and subsequent transient migration to a steady structure is described, focussing on the processes by which the transition occurs. A side-by-side comparison of vortices generated with and without the impact of Coriolis forces is made using 3 component planar velocity field data in a reference plane moving with the vortex ring. Subsequent to generation, an axially aligned vortex wake is formed, which is shown to induce a secondary vortex shedding phenomenon.
