Verification and Validation of a Fully-Coupled Three-Dimensional Low-Temperature Plasma and Reactive Navier Stokes Solver

The three-dimensional exascale reactive solver PeleC with Adaptive Mesh Refinement (AMR) capabilities is extended to simulate low-temperature plasma streamer discharges. Charged species fluxes are modeled using the drift-diffusion approximation, which is incorporated in a consistent manner with the PeleC reactive Navier-Stokes formulation. The Poisson equation for the electrostatic potential is solved in conjunction with the conservation of charged species. The solver implementation is validated against established benchmarks. The benchmarking exercise paves the way for future three-dimensional large-scale simulations of coupled low-temperature plasma-assisted ignition in turbulent reactive flows.
