AC Electric Discharges in Gas–Liquid Medium of a Sodium Chloride Solution at Atmospheric Pressure

The results of experimental studies of the electric discharge of alternating current ( f = 50 Hz) in a gas–liquid environment of an electrolyte with bubbles for interelectrode distances of 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 is established using the fast Fourier transform. Based on the analysis of the experimental data, the mechanism for the development of an alternating current electric discharge in a medium with microbubbles is established.
