Bridging kinetic plasma descriptions and single fluid models
A. Crestetto, F. Deluzet, D. Doyen
The purpose of this paper is to bridge kinetic plasma descriptions and low frequency single fluid models. More specifically, the asymptotics leading to Magneto-Hydro-Dynamic (MHD)…

Kinetic/Fluid micro-macro numerical scheme for a two component gas mixture
A. Crestetto, C. Klingenberg, M. Pirner
This work is devoted to the numerical simulation of the \BGK equation for two species in the fluid limit using a particle method. Thus, we are interested in a gas mixture consistin…

A hybrid method for anisotropic elliptic problems based on the coupling of an Asymptotic-Preserving method with the Asymptotic-Limit model
Anais Crestetto, Fabrice Deluzet, Claudia Negulescu
This paper presents a hybrid numerical method to solve efficiently a class of highly anisotropic elliptic problems. The anisotropy is aligned with one coordinate-axis and its stren…
