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…
A BGK model for high temperature rarefied gas flows
Céline Baranger, Yann Dauvois, Gentien Marois +3
High temperature gases, for instance in hypersonic reentry flows, show complex phenomena like excitation of rotational and vibrational energy modes, and even chemical reactions. Fo…
Locally refined discrete velocity grids for stationary rarefied flow simulations
Céline Baranger, Jean Claudel, Nicolas Hérouard +1
Most of deterministic solvers for rarefied gas dynamics use discrete velocity (or discrete ordinate) approximations of the distribution function on a Cartesian grid. This grid must…
Explicit spectral gap estimates for the linearized Boltzmann and Landau operators with hard potentials
Céline Baranger, Clément Mouhot
This paper deals with explicit spectral gap estimates for the linearized Boltzmann operator with hard potentials (and hard spheres). We prove that it can be reduced to the Maxwelli…
