Derivation of the Enskog--Enskog System from a Particle System
Zhe Chen
We formally derive a coupled Enskog system for a gas--particle mixture from the hard-sphere BBGKY hierarchy. The derivation retains the finite separation between colliding centres,…
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…
A Fourier spectral immersed boundary method with exact translation invariance, improved boundary resolution, and a divergence-free velocity field
Zhe Chen, Charles S. Peskin
This paper introduces a new immersed boundary (IB) method for viscous incompressible flow, based on a Fourier spectral method for the fluid solver and on the nonuniform fast Fourie…
