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…
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…
An Approximate Model for Radiative Transfer in Slab Geometry
Graham Alldredge, Ruo Li, Weiming Li
We propose an approximate second order maximum entropy () model for radiative transfer in slab geometry. The model is based on the ansatz of the specific intensity in the form…
