The paper presents results of the experimental and numerical studying the electric discharge properties formed between a metal cathode and the liquid (non-metallic) anode at the atmospheric pressure. The discharge is ignited by immersing the metal cathode (AMC-40 aluminum) into the electrolytic anode (3% NaCl in the purified water). The paper analyzes the discharge electrophysical parameters, including the volt-ampere characteristic, current pulsations, and the discharge voltage. The electrode surface temperature in the discharge combustion zone is studied using the infrared thermography. The paper presents results of the numerical computation of the electron and ion components evolution, taking into account the plasma-chemical transformations between them. It considers the ionization and detachment processes as the sources of an electron component, and the electron attachment to neutrals and electron-ion recombination as its sinks.
