An implicit unified gas-kinetic wave-particle method for radiative transport process
Chang Liu, Weiming Li, Peng Song +1
The unified gas-kinetic wave-particle method (UGKWP) has been developed for the multiscale gas, plasma, and multiphase flow transport processes for the past years. In this work, we…
Direct Flux Gradient Approximation to Close Moment Model for Kinetic Equations
Ruo Li, Weiming Li, Lingchao Zheng
To close the moment model deduced from kinetic equations, the canonical approach is to provide an approximation to the flux function not able to be depicted by the moments in the r…
An asymptotic-preserving IMEX method for nonlinear radiative transfer equation
Weiming Li, Peng Song, Yanli Wang
We present an asymptotic preserving method for the radiative transfer equations in the framework of PN method. An implicit and explicit method is proposed to solve the P N system b…
A hybrid moment method for multi-scale kinetic equations based on maximum entropy principle
Weiming Li, Peng Song, Yanli Wang
We propose a hybrid moment method for the multi-scale kinetic equations in the framework of the regularized moment method [7]. In this method, the fourth order moment system is cho…
Unified Gas-kinetic Wave-Particle Methods III: Multiscale Photon Transport
Weiming Li, Chang Liu, Yajun Zhu +2
In this paper, we extend the unified gas-kinetic wave-particle (UGKWP) method to the multiscale photon transport. In this method, the photon free streaming and scattering processes…
A Nonlinear Three-Moment Model for Radiative Transfer in Spherical Symmetry
Ruo Li, Weiming Li, Lingchao Zheng
We study the approximation of the radiative transfer equation with a relatively few moments in the spherically symmetric case. We propose a three-moment model based on choosing the…
