The aim of this work is to investigate by means of a 3-D numerical model the behaviour of a transferred arc plasma torch operating at atmospheric pressure, for the cutting of a metallic substrate material, using a customized version of the CFD commercial code FLUENT©. The metallic substrate and the keyhole are included in the computational domain in order to take into account their effects on the flow field of the discharge at the nozzle exit. The detailed gas injection section and the cathode chamber are included in the computational domain as well.
