Abstract

Vortex rings are one of the most robust and fundamentally important fluid-structure in vorticity dominated flows. The rolling up of a slug of fluid mass, impulsively pushed out of an orifice, is generally stable. Owing to proposition of many applications of such flows, in the present study, an attempt has been made to characterize the nature of formation of vortex rings formed due to orifice in the presence of an axial rod. Experimental investigations are carried out to find the conditions under which the generated vortex ring is initially laminar or turbulent for various parameters. The results are used to draw a transition map pointing out the regions of different flow behavior.
