Parallel simulation of rarefied gas flows on unstructured meshes using the DIG-augmented DSMC method
Tao Huang, Liyan Luo, Hong Deng +1
While the direct simulation Monte Carlo (DSMC) is a mainstream stochastic particle method for simulating rarefied gas flows, it incurs excessively high computational costs in the n…

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…
