We propose a kinetic model of BGK type for a gas mixture of an arbitrary number of species
with arbitrary collision law. The model features the same structure of the corresponding …

We consider the Bathnagar–Gross–Krook (BGK) model, an approximation of the Boltzmann
equation, describing the time evolution of a single momoatomic rarefied gas and satisfying …

This minicourse contains a description of recent results on the modelling of rarefied gases in
weakly non equilibrium regimes, and the numerical methods used to approximate the …

Gas mixtures are important for many practical applications. Extending kinetic model
equations of the Bhatnagar–Gross–Krook (BGK) type from a single-species gas to a multi …

The main concern of the present paper is the study of the multi-scale dynamics of
thermonuclear fusion plasmas via a multi-species Fokker-Planck kinetic model. One of the …

We derive a multi-species BGK model with velocity-dependent collision frequency for a non-
reactive, multi-component gas mixture. The model is derived by minimizing a weighted …

We consider a kinetic description of multi-species gas mixture modeled with Bhatnagar-
Gross-Krook (BGK) collision operators, in which the collision frequency varies not only in …

Practical applications involve flows that often have more than one constituent. Therefore, the
capability to model a gas mixture flow is important. Extending kinetic model equations of the …

A multi-scale implicit multi-degree-of-freedom (MDOF) kinetic model with molecular
translational, rotational and vibrational effects is presented. The evolution and exchange of …

We generalize the BGK model proposed in Bisi and Cáceres (2016) to a mixture constituted
by both monoatomic and polyatomic gas species with each polyatomic one being …
