Relativistic BGK model for reactive gas mixtures
Seung-Yeon Cho, Byung-Hoon Hwang, Myeong-Su Lee +1
We propose a BGK-type kinetic model for relativistic reactive gas mixtures. This model serves as a computationally tractable yet physically consistent alternative to the correspond…

Stationary solutions to the relativistic BGK model for gas mixtures in a slab
Byung-Hoon Hwang, Myeong-Su Lee
In a recent paper [16], the authors proposed a BGK model for relativistic gas mixtures based on the Marle-type approximation, which satisfies the fundamental kinetic properties: no…

Classical solutions to a BGK-type model relaxing to the isentropic gas dynamics
Byung-Hoon Hwang
In this paper, we consider a BGK-type kinetic model relaxing to the isentropic gas dynamics in the hydrodynamic limit. We introduce a linearization of the equation around the globa…
