Boosting the convergence of low-variance DSMC by GSIS
Liyan Luo, Qi Li, Lei Wu
The low-variance direct simulation Monte Carlo (LVDSMC) is a powerful method to simulate low-speed rarefied gas flows. However, in the near-continuum flow regime, due to limitation…

A kinetic model for rarefied flows of molecular gas with vibrational modes
Qi Li, Lei Wu
A kinetic model is proposed for rarefied flows of molecular gas with rotational and temperature-dependent vibrational degrees of freedom. The model reduces to the Boltzmann equatio…
