A deterministic solver for the linear Boltzmann model of a single mono-directional proton beam
Xiaojiang Zhang, Xuemin Bai, Min Tang
The linear Boltzmann model for proton beams is a six-dimensional partial differential equation (PDE). We propose a deterministic solver for the linear Boltzmann model based on scat…
Asymptotic-preserving particle-in-cell method for the magnetized Vlasov--Poisson--Fokker--Planck equation
Anjiao Gu, Xiaojiang Zhang
In this work, we develop and rigorously analyze a new class of particle methods for the magnetized Vlasov--Poisson--Fokker--Planck system. The proposed approach addresses two funda…
A fully asymptotic preserving decomposed multi-group method for the frequency-dependent radiative transfer equations
Xiaojiang Zhang, Peng Song, Yi Shi +1
The opacity of FRTE depends on not only the material temperature but also the frequency, whose values may vary several orders of magnitude for different frequencies. The gray radia…
A Spatial-Temporal asymptotic preserving scheme for radiation magnetohydrodynamics in the equilibrium and non-equilibrium diffusion limit
Shi Jin, Min Tang, Xiaojiang Zhang
The radiation magnetohydrodynamics (RMHD) system couples the ideal magnetohydrodynamics equations with a gray radiation transfer equation. The main challenge is that the radiation…
