Plasma Sound Source Basic Research.

Abstract

This research focuses on the problem of understanding the mechanisms by which the underwater spark is generated and the delivery of electrical energy to the arc load and ultimately the acoustic signal. Recent progress in numerical simulations of arc-generated bubbles in water show good agreement with experimental observations. The arc formation and dielectric breakdown of the water at moderate field strengths have been modeled with a fractal object. Good agreement with electrical characteristics has been obtained. The limitations of multi-gap electrodes in water have been characterized.
