Experimental Investigation of the Dynamics and Space Range of the Gliding Arc in Three-Electrode System

The gliding discharge visualization in mixed streams of argon and oxygen was recorded with the use of a high-speed camera in order to test a plasma reactor new gas supply system, which consisted of two nozzles of a special shape. The plasma reactor was equipped with three electrodes powered by a three-phase alternating current. The estimated maximal discharge diameter was 32 mm. The diameter of the gas stream, where the stoichiometric composition of reactants was reached, amounted to 8 mm, and it was smaller than the maximal discharge diameter. In these conditions, it may be expected that the efficiency of the chemical reaction should be the highest for given experimental conditions.
