Abstract

The current work describes the global stability analysis of the plasma jet in an Inductively Coupled Plasma (ICP) facility. We consider the Center for Hypersonics and Entry System Studies’ Plasmatron X ICP facility located at the University of Illinois Urbana-Champaign. The global stability analysis is performed with a linear operator matrix extracted by linearizing the spatially discretized Navier-Stokes equations about a steady base state in local thermodynamic equilibrium. The linear operator is extracted numerically, thus making the method robust and allowing it to be applied to any general flow field. For the ICP operating conditions considered in the current study, two unstable eigenvalues are found that qualitatively resemble Kelvin-Helmholtz instability modes.
