Abstract
The mathematical model is presented, describing a turbulent flow of the electric arc plasma in air-vapour plasmatrons with a refractory cathode. The effect of operating parameters of a plasmatron and kind of the employed plasma gas on electric and energy characteristics of the arc, as well as on thermal and gas-dynamic characteristics of the plasma flow generated by such a plasmatron, is numerically studied.
