HYDRODYNAMICS OF A VORTEX RING 

V. I. Korobko and I. V. Chekh

UDC 538.517.4 

We considered the kinematics and dynamics of a vortex 
ring in an incompressible fluid in toroidal coordinates. We obtained 
the change in the pressure difference along the boundary between two 
flow regions in the case of a moving torus.
