A Multispecies ESBGK Model for Gas Mixtures with Variable Hard Sphere Transport: Theory and Verification
Marcel Pfeiffer, Franziska Tuttas, Julien Mathiaud +1
A multi-species Bhatnagar-Gross-Krook (BGK) model for gas mixtures is presented that achieves the correct species-wise relaxation of velocities, temperatures, and pressure tensors…

An ES-BGK model for diatomic gases with correct relaxation rates for internal energies
Julien Mathiaud, Luc Mieussens, Marcel Pfeiffer
We propose a new ES-BGK model for diatomic gases which allows for translational-rotational and translational-vibrational energy exchanges, as given by Landau-Teller and Jeans relax…
