Abstract

The paper deals with modeling the dynamics of changes in plasma parameters occurring in the channels and in the electric arc chamber of a two-housing AC plasma torch at atmospheric pressure. A numerical calculation of the key parameters of gas-discharge processes was performed, characterizing the distribution of temperature fields and arc voltage drop in the plasma torch’s working zone. A comparative analysis of the obtained data with experimentally measured parameters confirms the validity of the developed model and its suitability for improving existing plasma torch designs, as well as for developing of a new plasma technology.
