Abstract : We present in this paper a 2D numerical modelling of a dc argon plasma torch. This model is based on the resolution of the electromagnetism and Navier-Stokes equations by the control volume method of Patankar. This model allows to describe the velocity and temperature fields between the electrodes and in the plasma jet. Turbulence phenomenon is taken into account by a Prandtl-s mixing length model. The results show the influence of turbulence on the flow fields and also the influence of current intensity and inlet mass flow rate on the characteristics of the plasma.
