Frequency-domain general synthetic iterative scheme for efficient simulation of oscillatory rarefied gas flows
Pengshuo Li, Lei Wu
Oscillatory rarefied gas flows are frequently encountered in MEMS, and their efficient numerical simulation remains a major challenge due to the time dependent nature of the proble…
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…
Coherent Rayleigh-Brillouin scattering: influences of intermolecular potentials and chirp rates
Lei Wu
Chirped coherent Rayleigh-Brillouin scattering (CRBS) is a flow diagnostic technique that offers high signal-to-noise ratios and nanosecond temporal resolution. To extract informat…
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…
