Abstract:
The results of experimental studies and numerical calculations of the parameters of an electric discharge with a liquid (nonmetallic) cathode in air flow at atmospheric pressure are presented. The shapes of plasma structures arising in the interelectrode gap are described. The plasma composition and electron concentration are determined by optical emission spectroscopy, and the temperature of the surface of the electrodes in the discharge burning zone is determined by the infrared thermography method. The current–voltage characteristic (CVC) of the discharge is plotted. The results of numerical calculations of the distributions of the power density of the Joule heat release and the electric field strength near the metal anode are presented. The formation of a vapor–liquid mixture around the part of the metal anode immersed in the electrolyte is described.
