Introduction,Vortex flow is one of the fundamental types of fluid and gas motion. These flows are the most spectacular in the form of concentrated vortices, characterized by the localization of vorticity (curl of velocity) in bounded regions of a space, beyond which the vorticity is either absent or rapidly falls down to zero.

Theoretical Models of Vortex Rings, Helmholtz, who founded the theory of vortex motions of fluids and also carried out a series of experimental observations of vortex ring motion (Helmholtz 1858). Experiments with the motion of air vortex rings colored with smoke and vortex rings in fluids visualized with dye showed that a vortex rin

Hydrodynamic Structure of a Vortex Ring,acteristics of vortex rings that form and exist in a real viscous fluid. Until recently, direct experimental studies of the hydrodynamic structure of real vortex rings have been lacking, and thus it has not been clear how realistically theoretical models of vortex rings reflect the actual phenomenon
