Abstract

Inductively coupled plasma (ICP) torches generate high-enthalpy jets to study the thermo-chemical response of materials at high temperatures. The current paper presents a simulation framework capable of modeling the plasma jet generated by an ICP facility in a three-dimensional and time-accurate manner. This framework provides a valuable resource for studying the hydrodynamics of plasma jets and for assisting in the design of experimental campaigns. The framework is applied to study the plasma jet in the University of Illinois at Urbana-Champaign Plasmatron X ICP facility and compare predictions with experimental data obtained using high-speed imaging. The comparison shows that the numerical results are qualitatively similar to the experimental data, providing preliminary validation for the simulation framework. The high-fidelity spatio-temporal numerical data are used to visualize and analyze the plasma jet. Under the adopted operating conditions, the plasma jet is found to be highly turbulent, with periodic releases of hot pockets of gas from the jet inlet being observed. The baroclinic torque is shown to have a significant effect in destabilizing the plasma jet flow field.
