Popis:	Gas-dynamic phenomena accompanying a ring electric discharge excited in atmospheric-pressure air have been studied experimentally and theoretically. It is shown experimentally that the discharge generates a toroidal (three-dimensional) shock wave that converges toward the axis. A mathematical model describing the focusing of a toroidal shock wave is constructed. The measured characteristics of shock processes accompanying the discharge agree well with results of calculations. This makes it possible to estimate the gas temperature that can be achieved in the convergent shock wave at a certain distance from the center of the ring discharge.
