The results of numerical experiment pertaining to the influence of highvoltage discharge in liquid on the discharge hydrodynamics are presented. It is shown that under fixed power source parame- ters oscillating discharge modes have to be used to obtain higher values of the discharge channel expan- sion velocity, pressure and specific impulsive force, and critical modes must be chosen for prolonged intervals of increased pressure influence and higher values of specific impulsive pressure in liquid.
