Implicit Update of the Moment Equations for a Multi-Species, Homogeneous BGK Model
Evan Habbershaw, Cory D. Hauck, Steven M. Wise
A simple iterative approach for solving a set of implicit kinetic moment equations is proposed. This implicit solve is a key component in the IMEX discretization of the multi-speci…
