Nodal discontinuous Galerkin methods for non-ideal equations of state: pressure equilibrium preservation and entropy correction
Jesse CHan, Hendrik Ranocha, Raymond Park +3
Structure-preserving discontinuous Galerkin (DG) methods typically improve the robustness of high order simulations of real fluids. In addition to conservation, key structures incl…
CodeJeNN: A simple C++ neural network generator for physics applications
Jay Arcities, Pavel Popov, Eric J Ching +2
Machine learning has shown promise for physics applications, but integrating Python-based libraries into high-performance C++ solvers can create performance bottlenecks. We present…
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…
Simulation of Non-Premixed, Supersonic Combustion using the Discontinuous Galerkin Method on Fully Unstructured Grids
Cal J. Rising, Eric J. Ching, Ryan F. Johnson
In this study, three-dimensional simulations of a reacting hydrogen jet in supersonic crossflow using a structure-preserving discontinuous Galerkin (DG) formulation are examined. T…
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…
Conservative discontinuous Galerkin method for supercritical, real-fluid flows
Eric J. Ching, Ryan F. Johnson
This paper presents a conservative discontinuous Galerkin method for the simulation of supercritical and transcritical real-fluid flows without phase separation. A well-known issue…
Effect of ozone sensitization on the reflection patterns and stabilization of standing detonation waves induced by curved ramps
Eric J. Ching, Ryan F. Johnson
Standing detonation engines are a promising detonation-based propulsion technology. The most commonly studied standing detonation configuration involves a straight-sided wedge that…
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…
Positivity-preserving and entropy-bounded discontinuous Galerkin method for the chemically reacting, compressible Euler equations. Part II: The multidimensional case
Eric J. Ching, Ryan F. Johnson, Andrew D. Kercher
In this second part of our two-part paper, we extend to multiple spatial dimensions the one-dimensional, fully conservative, positivity-preserving, and entropy-bounded discontinuou…
