Analysis of the characteristics of the direct current discharge in the electrolyte medium at low pressure

Abstract

The results of experimental studies of direct current electric discharge in the gas-liquid medium of an electrolyte with bubbles for various interelectrode distances (l=50-150 mm) inside a dielectric tube are presented. The presence of a bubble structure with microdischarges affects the nature of the discharge current and voltage ripples. The frequency spectrum of voltage and current oscillations of the discharge was established using the fast Fourier transform. Based on the analysis of experimental data, a mechanism for the development of a direct current electric discharge with a gas-liquid medium with air bubbles and microdischarges has been established.
