Summary: | The characteristics and mathematical modeling of the behavior of a low-temperature direct-current electric discharge plasma ignited between an aluminum anode and an electrolytic cathode (3% NaCl solution in purified water) at atmospheric pressure are investigated. The discharge is ignited by immersing the metal anode into the electrolytic cathode. The types and forms of plasma structures generated in the interelectrode gap are considered. The results of high-speed recording of the discharge breakdown and combustion are presented. The electrophysical parameters of the discharge, including pulsations and current/voltage fluctuations are studied. The emission spectroscopy method is used to determine the discharge emission spectrum, plasma composition, electron concentration, and temperature of heavy plasma components. The heat patterns of the surface of liquid nonmetallic and metallic electrodes in the discharge combustion zone are considered. The results of numerical simulation of electric field strength and the initial stage of the discharge are presented. |
