Abstract
Numerical calculations of pulsation period of a toroidal bubble on the edge of a round diaphragm current concentrator during electric discharge in electrolyte were performed for the self-oscillations mode. It was shown both theoretically and experimentally that the dependence of the period of the pulsations on the applied voltage has a minimum. This minimum corresponds to the conditions of the change in the leading mechanism of the bubble growth. The derived formula for the bubble pulsation period is in a good agreement with experimental data on discharges with the round diaphragms of the radii from 0.025 to 0.75Â mm.
