ChemGen: Code Generation for Multispecies Chemically Reacting Flow Simulations
Ryan F. Johnson, Eric J. Ching, Ethan S. Genter +4
This paper introduces ChemGen, a software package that uses code generation to integrate multispecies thermodynamics and chemical kinetics into C+-based computational physics codes…
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…
The Moving Discontinuous Galerkin Method with Interface Condition Enforcement for the Simulation of Hypersonic, Viscous Flows
Eric J. Ching, Andrew D. Kercher, Andrew Corrigan
The moving discontinuous Galerkin method with interface condition enforcement (MDG-ICE) is a high-order, r-adaptive method that treats the grid as a variable and weakly enforces th…
A note on reducing spurious pressure oscillations in fully conservative discontinuous Galerkin simulations of multicomponent flows
Eric J. Ching, Ryan F. Johnson, Andrew D. Kercher
A well-known issue associated with the use of fully conservative schemes in multicomponent-flow simulations is the generation of spurious pressure oscillations at contact interface…
