This work presents the heat and mass transfer modelling of 100 kW three phase AC plasma torch operating with air. The AC transient phenomena taking place in the arc region are simplified using a source model. A parametric study is performed to investigate the robustness of this simplification. The model includes gas and wall radiation. Results show the impact of radiation on the temperature field and wall heat losses.
