A Particle Multi-Relaxation Bhatnagar-Gross-Krook Method for Rarefied Monatomic Gas Mixtures
Inchan Kim, Joonbeom Kim, Woonghwi Park +1
Kinetic models based on the Bhatnagar-Gross-Krook (BGK) framework provide an efficient alternative to the Boltzmann equation for rarefied gas flows; however, existing formulations…

A second-order particle Fokker-Planck-Master method for diatomic gas flows
Joonbeom Kim, Eunji Jun
The direct simulation Monte Carlo (DSMC) method is widely used to describe rarefied gas flows. The DSMC method accounts for the transport and collisions of computational particles,…

Improving Spatio-Temporal Accuracy of the Stochastic Particle Fokker-Planck Model
Joonbeom Kim, Eunji Jun
Accurate prediction of rarefied gas flows is important for space vehicle design, particularly in rarefied regimes where the Navier-Stokes equations are no more valid. While the dir…
