Fast-Converging and Asymptotic-Preserving DSMC
Bin Hu, Liyan Luo, Kaiyuan Wang +1
Improving the efficiency of the direct simulation Monte Carlo (DSMC) method has become increasingly urgent with the rapid development of space exploration. To address this issue, t…
Accelerating the Monte Carlo simulation of the Enskog equation for multiscale dense gas flows
Bin Hu, Liyan Luo, Lei Wu
A general synthetic iterative scheme is proposed to solve the Enskog equation within a Monte Carlo framework. The method demonstrates rapid convergence by reducing intermediate Mon…
Temperature jump coefficients in polyatomic gas with strong translational/internal non-equilibrium
Bin Hu, Lei Wu
The temperature jump problem in polyatomic gas flow with translational/internal non-equilibrium is investigated, where the internal temperature is excited by volumetric heating, wh…
NiST: a non-localized spatial-temporal constitutive relation in rarefied gas dynamics
Xiaoda Li, Bin Hu, Lei Wu
Although the mesoscopic Boltzmann equation describes the rarefied gas dynamics, finding its solutions in complicated engineering problems is challenging. Therefore, over the past o…
