要約

An external hydrodynamic problem of electric discharge in water is considered under the condition of energy supplied in the cylindrical channel as a sequence of pulses. The corresponding initial-boundary problem with mobile boundary for wave equation is formulated. The problem analytical solution is obtained by the method of nonlinear time transformation. It is shown how the small pulsations imposed on the linear law of channel radius growth affect the process development. Peculiarities of hydrodynamic characteristics of the electric discharge are revealed.
