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…

Enhancing DSMC simulations of rarefied gas mixtures using a fast-converging and asymptotic-preserving scheme
Liyan Luo, Jianan Zeng, Yanbin Zhang +3
The numerical simulation of rarefied gas mixture dynamics with disparate masses using the direct simulation Monte Carlo (DSMC) method is slow, primarily because the time step is co…

Adaptive GSIS for rarefied gas flow simulations
Yanbing Zhang, Jianan Zeng, Lei Wu
The parallel solver of the general synthetic iterative scheme (GSIS), as recently developed by Zhang \textit{et. al.} in Comput. Fluids 281 (2024) 106374, is an efficient method to…
