Unified gas-kinetic simulation for the system of multiscale radiation hydrodynamics
Wenjun Sun, Song Jiang, Kun Xu +1
This paper aims at the simulation of multiple scale physics in the system of radiation hydrodynamics. The system couples the fluid dynamic evolution equations with the radiative he…
High-order gas-kinetic scheme with three-dimensional WENO reconstruction for the Euler and Navier-Stokes solutions
Liang Pan, Kun Xu
In this paper, a simple and efficient third-order weighted essentially non-oscillatory (WENO) reconstruction is developed for three-dimensional flows, in which the idea of two-dime…
Ray Effect in Rarefied Flow Simulation
Yajun Zhu, Chengwen Zhong, Kun Xu
Ray effect usually appears in the radiative transfer when using discrete ordinates method (DOM) in the simulations. The cause and remedy for the ray effect have been intensively in…
On unified preserving properties of kinetic schemes
Zhaoli Guo, Jiequan Li, Kun Xu
The kinetic theory provides a physical basis for developing multiscal methods for gas flows covering a wide range of flow regimes. A particular challenge for kinetic schemes is whe…
On the fallback disk around the slowest isolated pulsar, 1E 1613485055
Kun Xu, Xiang-Dong Li
The central compact object 1E 1613485055 in the supernova remnant RCW 103 has a spin period hr, making it the slowest isolated pulsar. It is believed that a supernov…
High-order ALE gas-kinetic scheme with unstructured WENO reconstruction
Liang Pan, Fengxiang Zhao, Kun Xu
In this paper, a high-order multi-dimensional gas-kinetic scheme is presented for both inviscid and viscous flows in arbitrary Lagrangian-Eulerian (ALE) formulation. Compared with…
