Abstract: Vortex rings are among the only consistent natural feature to achieve effective transport of mass, momentum, and energy in fluids.For most scenarios where each of these transport mechanisms are utilized, efficiency of the vortex generator is parameterized by how much vorticity is entrained by the created vortex ring-the more vorticity that a vortex ring entrains during the formation process, the more efficient each of the transport mechanisms will be.They cannot grow indefinitely, however.Vortex ring formation is known to be limited by a dimensionless ratio that compares the length of an ejected slug of fluid L to its diameter D. This ratio is termed formation time, Ţ = L/D, and has a limiting value of
