Experimental Investigation of the Pressure Waves Generated by an Electric Explosion in a Closed Volume of a Fluid

详细

Experimental investigations of the pressure wave amplitude generated by an electrical explosion in a closed volume of a fluid at elevated hydrostatic pressures were performed. In the process of the experiments, the influence of characteristics of the discharge circuit on the pressure wave amplitude in underwater spark discharge was evaluated, and the spark discharge was compared with the electric wire explosion by this parameter. The results showed that the decrease in the inductance and increase in the charging voltage lead to an increase in the amplitude of the pressure wave generated by the underwater spark discharge. The application of the electric wire explosion stabilizes the parameters of the generated pressure wave, allows one to increase its amplitude, and to reduce at the same time the charging voltage rate.
