Abstract

A new technique for the treatment of the electromagnetic field is proposed for numerically studying inductively coupled plasma torches within FLUENT^© environment. The method is based on the use of a linked external routine which fully solves the electromagnetic field equations on an extended grid, allowing the fluid-dynamics domain to be limited to the torch region. The advantages of the new approach with respect to that using entirely FLUENT^© are pointed out. Comparisons between results obtained employing either magnetic dipole or zero potential boundary conditions for the electromagnetic field are presented. All the calculations have been performed for a 2D axisymmetric torch under the assumptions of laminar flow for the L.T.E., optically thin argon plasma.
