Self-consistent Modeling of Inductively Coupled Plasma Discharges

The purpose of this work is the development of a self-consistent multi-physics modeling framework for ICP discharges. Unlike a monolithic approach, the hydrodynamics and electromagnetic field are handled by separate solvers, all developed within the Center for Hypersonics and Entry Systems Studies (CHESS) at the University of Illinois. Hydrodynamics is modeled using HEGEL , a finite volume solver for non-equilibrium plasmas. This solver is interfaced with the PLATO library, which is responsible for evaluating all plasma-related quantities (e.g., thermodynamic and transport properties). The electric field is handled by FLUX , a finite element solver. Coupling is realized using the PRE CICE open-source library. Applications are here presented and discussed to demonstrate the effectiveness of the proposed modeling strategy.
