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…
A novel spatial distribution method for wind farm parameterizations based on the Gaussian function
Bowen Du, Qi Li, Mingwei Ge +2
Wind farm parameterizations are crucial for quantifying the wind-farm atmosphere interaction, where wind turbines are typically modeled as elevated momentum sinks and sources of tu…
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…
General synthetic iterative scheme for multiscale radiative transfer in the finite-volume framework
Kaiyuan Wang, Yanbing Zhang, Qi Li +1
Achieving efficient and accurate simulation of the radiative transfer has long been a research challenge. Here we introduce the general synthetic iterative scheme as an easy-to-imp…
Multiscale simulation of rarefied polyatomic gas flow via DIG method
Liyan Luo, Tao Huang, Qi Li +1
A novel multiscale numerical method is developed to accelerate direct simulation Monte Carlo (DSMC) simulations for polyatomic gases with internal energy. This approach applies the…
