Abstract: A new discrete Boltzmann model, the discrete ellipsoidal statistical Bhatnagar–Gross–Krook (ESBGK) model, is proposed to simulate nonequilibrium compressible flows. Compared with the original discrete BGK model, the discrete ES-BGK has a flexible Prandtl number. For… read more here.

Abstract: Abstract Kinetic models of polyatomic gas typically account for the internal degrees of freedom at the level of the two-particle distribution function. However, close to the hydrodynamic limit, the internal (rotational) degrees of freedom tend… read more here.

DOI: 10.1063/1.5017899
Abstract: Ellipsoidal BGK model (ES-BGfK model) is a model equation for the Boltzmann equation designed to give correct a Prandtl number in the Navier-Stokes limit. In this paper, we consider the existence of classical solutions and… read more here.
