Conservative Formulations of the Standard Enskog and Povzner Equations
Zhe Chen
This article introduces a conservative formulation of the Standard Enskog equation and the Povzner equation, both of which generalize the Boltzmann equation by incorporating the co…

A Formal Derivation of the Thick Spray Model from the Enskog-Boltzmann System
Zhe Chen
We propose a specific scaling that formally derives the Euler-Vlasov model for thick sprays which is widely adopted in engineering from the Boltzmann-Enskog model. Beyond validatin…

Local Conservation Laws and Entropy Inequality for Kinetic Models with Delocalized Collision Integrals
Frédérique Charles, Zhe Chen, François Golse
This article presents a common setting for the collision integrals appearing in the kinetic theory of dense gases. It includes the collision integrals of the Enskog e…
