Modeling of Analysis ICP Torch at Atmospheric Pressure With Applied Voltage

In this paper, a new 2-D nonlinear direct-coupled model for the simulation of inductively coupled plasma torches working at atmospheric pressure is presented. Steady fluid flow and temperature equations are simultaneously solved (direct method) using a finite-element formulation for optically thin argon plasmas under the assumptions of local thermodynamic equilibrium and laminar flow. The electromagnetic field equations are formulated in terms of potential vector with applied voltage source.
