A general synthetic iterative scheme with high-order spatial discretization for rarefied gas mixture flows
Jianan Zeng, Wei Su
We develop a high-order discontinuous Galerkin formulation of the general synthetic iterative scheme (GSIS) for steady rarefied gas mixture flows. The resulting GSIS-DG discretizes…
Accelerated simulation of multiscale gas-radiation coupling flows via a general synthetic iterative scheme
Jianan Zeng, Qi Li, Yanbing Zhang +2
Gas-radiation coupling critically influences hypersonic reentry flows, where extreme temperatures induce pronounced non-equilibrium gas and radiative heat transport. Accurate and e…

Transition of a system between two states is an important but difficult problem in natural science. In this article we study the transition problem in the framework of transition p…
Kinetic modelling of rarefied gas flows with radiation
Qi Li, Jianan Zeng, Lei Wu
Two kinetic models are proposed for high-temperature rarefied (or non-equilibrium) gas flows with radiation. One of the models uses the Boltzmann collision operator to model the tr…
