Abstract
Mathematical model is presented, describing the heat and mass transfer processes occurring in interaction of external gas environment with a turbulent flow of the arc plasma generated by plasmatron with an anode wire. Comparative numerical analysis of spatial distributions of heat, gas-dynamic and other characteristics of the turbulent jet of the argon plasma blown about with laminar argon and air flows, as well as emitted into a quiescent gas, was conducted.
Keywords: arc plasma, plasmatron, anode wire, mathematical model, numerical analysis, turbulent jet, concurrent flow, heat and mass transfer
