Conservative, pressure-equilibrium-preserving discontinuous Galerkin method for compressible, multicomponent flows
Eric J. Ching, Ryan F. Johnson, Andrew D. Kercher
This paper concerns preservation of velocity and pressure equilibria in smooth, compressible, multicomponent flows in the inviscid limit. First, we derive the velocity-equilibrium…
