Impacts of electrode structure on plasma discharge in pre-breakdown period for water environment treatment

Abstract

Abstract Since the liquid discharge problem has been incorporated into the line of sight, many scholars have done a lot of research on it. In this paper, experiments on the pre-breakdown period in underwater plasma discharge were carried out. Among the parameters of underwater plasma discharge, the electrode structure is firstly taken account by virtue of its intuitive, easy-to-process, and diversity. With the refinement of the application of liquid discharge in liquid-electric processing, research on the effect of electrode structure on underwater plasma discharge is deepening. In this paper, two sets of electrode groups were proposed in a pioneering manner through the theoretical analysis and precise control of the experimental parameters. Based on the experimental results, rigorous and reliable analysis and summary were demonstrated. The conclusions of this paper would be helpful for water environmental treatment.
