Resumen:
A two-dimensional turbulent model of a low-current intensity (30 A) cutting plasma torch was developed using the local thermodynamic equilibrium approximation. A good agreement was found between measured and modelled results of plasma temperature and velocity, the latter of which has not been previously reported in the literature for high energy density torches. The cutting performance was also studied in terms of the heat flux to the work-piece and the value of the force exerted by the impinging plasma jet.
