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…

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…
