Abstract
The impulse sound source generated by the underwater pulse discharge technology based on the hydroelectric effect is widely used in the fields of seismic source simulation,oilfield plugging and stimulation,pipeline descaling,stone crushing,sewage treatment and other fields.Among them,the generation of impulse sound source is affected by many factors such as loop parameters and gap distance.The study and analysis of the influence of various factors on the hedge excitation sound source is helpful to promote the further application of the impulse sound source.In this paper,the underwater plasma discharge process of the rod-ring electrode structure is numerically simulated,and the finite element analysis method is used to study the structure of the rod-ring electrode theoretically,and the influence of different initial conditions on the hedging shock wave characteristics is obtained.Based on the rod-ring electrode structure,the effects of the charging voltage and electrode gap on the rod-ring electrode structure are studied,and the goal is to find the sound source with stronger impulse shock,wider frequency band and higher energy.This paper can provide a reference for the practical application of rod-ring electrodes.关键词
