Abstract
With the use of numerical modeling an investigation of the process of the
formation of stable high-momentum vortex rings obtained with the aid of a
special generator of shock waves, the structure of such rings, and their motion in
an ambient medium at rest has been carried out. The vortex rings can move at
rather large distances without a significant energy loss and are able to transfer
the finely dispersed liquid or solid particles, which enables one to use them in
various practical applications, including also the development of a weapon of
non-lethal action. The results of numerical modeling agree quite satisfactorily
with the experimental results in terms of sizes of such rings and the velocities of
their motion in space carried out at the Institute of Chemical Technologies
(Pfinztal, Germany).
