@article{Yang2021HighorderGS, title={High-order gas-kinetic scheme for radiation hydrodynamics in equilibrium-diffusion limit}, author={Yaqing Yang and Liang Pan and Wenjun Sun}, journal={ArXiv}, year={2021}, volume={abs/2110.06557} }

In this paper, a high-order gas-kinetic scheme is developed for the equation of radiation hydrodynamics in equilibrium-diffusion limit which describes the interaction between matter and radiation. To recover RHE, the Bhatnagar-Gross-Krook (BGK) model with modified equilibrium state is considered. In the equilibrium-diffusion limit, the time scales of radiation diffusion and hydrodynamic part are different, and it will make the time step very small for the fully explicit scheme. An implicit…
