Octant Flux Splitting Information Preservation DSMC Method for Thermally Driven Flows
Journal of Computational Physics, 2007 We present the octant flux splitting DSMC method as an efficient method for simulating non-equilibrium flows of rarefied gas, particularly those arising from thermal loading.

Cubic Fokker-Planck-DSMC Hybrid Method for Diatomic Rarefied Gas Flow Through a Slit and an Orifice
Vacuum, 2019 Fokker-Planck kinetic models have been devised as an approximation of the Boltzmann collision operator. Cubic Fokker-Planck-DSMC hybrid method is employed to simulate the diatomic gas flow through a thin slit and a thin orifice.

Assessment of the LD-DSMC Hybrid Method for Hypersonic Rarefied Flow
Computers and Fluids, 2018 Hypersonic aerothermodynamics for a probe entering a planetary atmosphere is an important issue in space exploration. The probe experiences various Knudsen number regimes, ranging from rarefied to continuum, due to density variation in the planet's ...
