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…

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…
