An ES-BGK model for vibrational polyatomic gases
Y Dauvois, J. Mathiaud, Luc Mieussens
We propose an extension of the Ellipsoidal-Statistical BGK model to account for discrete levels of vibrational energy in a rarefied polyatomic gas. This model satisfies an H-theore…
Numerical boundary conditions in Finite Volume and Discontinuous Galerkin schemes for the simulation of rarefied flows along solid boundaries
Céline Baranger, Nicolas Hérouard, Julien Mathiaud +1
We present a numerical comparison between two standard finite volume schemes and a discontinuous Galerkin method applied to the BGK equation of rarefied gas dynamics. We pay a part…
BGK and Fokker Planck Models for thermally perfect gases
J. Mathiaud, Luc Mieussens
We propose two models of the Boltzmann equation (BGK and Fokker-Planck models) for rarefied flows of thermally perfect gases. These models take into account various models of energ…
BGK and Fokker-Planck models of the Boltzmann equation for gases with discrete levels of vibrational energy
J. Mathiaud, Luc Mieussens
We propose two models of the Boltzmann equation (BGK and Fokker-Planck models) for rarefied flows of diatomic gases in vibrational non-equilibrium. These models take into account t…
