The paper investigates the processes of heat and gas mass transfer under the generalized physico-mathematical model of both plasma jet generators and plasma torches (also referred to as transferred- and non-transferred arc plasmatrons). A method is presented of solving the system of equations of the monoliquid arc model by introducing simplifying assumptions which make it equivalent to the two-layer arc model. The boundary condition on the surface of the cylindrical part of the column is given. The phenomena and thermophysical characteristics of plasma in both the cylindrical and the conical part of the column are described. A new method is offered for formulating an additional internal boundary condition of heat transfer in the plasma-gas system. The cases considered include the arc stabilized by metal walls, by laminar or turbulent gas flow in the discharge channel of a plasma jet generator, as well as the arc stabilized by gas flow in plasma torches used for melting metal pieces.
