Abstract :
[en] This study investigates the spatial propagation of pressure waves in a liquid during high-voltage electrical discharge (HVED) using numerical modeling and semi-empirical expressions. It is found that the amplitude of the pressure wave in the equatorial plane of the discharge channel decreases according to a power law, which is in good agreement with previously obtained results. The pressure distribution along the normal, drawn to the equatorial plane of the channel discharge, can be represented by a power dependence. In this case, the exponent decreases with the direction of the distance from the source of disturbance in the equatorial plane. A comparison of the results of mathematical modeling and experiments showed satisfactory agreement. The main limitations of the model include neglect of the viscosity of the liquid. The novelty of this study lies in the simultaneous use and direct comparison of two fundamentally different modeling approaches-a semi-empirical method and a numerical simulation-for assessing pressure wave propagation in both equatorial and non-equatorial planes. The obtained dependences can be used to assess the efficiency of electric discharge action on an object with a known tensile strength at any point in the working space.
