Краткое описание

An experimental approach is presented for the analysis of thermal characteristics of a linear plasma torch with a hot cathode and a step-shaped anode. The experiment is performed in air at atmospheric pressure for discharge currents of 175−245 A and voltage of 200−250 V. The fed gas flow rate varied in the range of (2.5−8.5)·10−3 kg·sec−1 , and the Reynolds number was (4−13)·103. The place of gas injection, flow distribution, and rate affect the heat-transfer characteristics of the plasma source, which were generalized employing the similarity theory.
