Abstract
The two-dimensional problem of the electric discharge hydrodynamics in liquid at the double- pulse law of energy lead-in in a discharge channel was solved by means of a finite-difference Godu- nov’s method. The hydrodynamic features of the process lying in the formation of a pressure pulse string in the channel and liquid surrounding it at the expense of change of the energy value, its lead-in time and rate of power of the second pulse rise were investigated. The numerical results received open up new possibilities of hydrodynamic properties of the electric discharge in liquid control.
