Physics-Based-Adaptive Plasma Model for High-Fidelity Numerical Simulations
Abstract
A physics-based-adaptive plasma model and an appropriate computational algorithm are developed to numerically simulate plasma phenomena in high-fidelity. The plasma model is 'refined' or 'coarsened' based on local physical plasma parameters to provide high fidelity throughout the domain. The plasma model uses continuum representations of the plasma, which include a kinetic description, multi-fluid plasma models (13N-moment and 5N-moment), and single-fluid MHD models. A blended finite element method is developed to implicitly treat the fastest physical phenomena and to explicitly treat the slower physical phenomena. The solution approach provides high-order accuracy and computational efficiency.
