Entropy-stable fluxes for high-order Discontinuous Galerkin simulations of high-enthalpy flows
Georgii Oblapenko, Arseniy Tarnovskiy, Moritz Ertl +1
In the present work, we extend the Discontinuous Galerkin Spectral Element Method (DGSEM) to high-enthalpy reacting gas flows with internal degrees of freedom. An entropy- and kine…

Linear regularized 13-moment equations with Onsager boundary conditions for general gas molecules
Zhenning Cai, Manuel Torrilhon, Siyao Yang
We develop the steady-state regularized 13-moment equations in the linear regime for rarefied gas dynamics with general collision models. For small Knudsen numbers, the model is ac…
