Abstract
A magnetohydrodynamic model of a plasma torch that describes the complete torch system from the gas injection, through the arc region, and out into the plasma plume is presented. It is a two-dimensional model but includes a swirl component of the flow and the K-ε model of turbulence and assumes local thermodynamic equilibrium. Temperatures in the plume of a plasma torch have been determined spectroscopically by measuring the emission from neutral argon atoms, and these temperatures have been compared with the predictions of the model.This publication has 12 references indexed in Scilit:
