Assessment of a Posteriori Positivity-Preserving Limiters for a Modal Discontinuous Galerkin Method Applied to Multicomponent Flows

When computing high-order solutions of compressible multicomponent flows, numerical instabilities at shock waves and material interfaces must be mitigated without compromising accuracy. A widely adopted strategy is the use of a posteriori limiters to enforce physical admissibility at the cell level. In this work, we co...
