Journal of Fluid Science and Technology, 2016 A micro size particle behavior considering thermophoretic and drag forces are simulated by using direct simulation Monte Carlo (DSMC) method. The computation time is too high to compute the micro particle movement by conventional DSMC method because the ...

DSMC Simulation of the Cometary Coma [PDF]
AIP Conference Proceedings, 2003 The study of the comet coma, or its tenuous atmosphere, is a major space application of rarefied gas dynamics, which requires modeling the gas flow in a wide range of Knudsen number. For weak to moderate comets, only the subsolar region of the coma is in a collision dominated regime.

Evaluation of Micronozzle Performance through DSMC, Navier-Stokes and Coupled DSMC/Navier-Stokes Approaches [PDF]
, 2009 Both the particle based Direct Simulation Monte Carlo (DSMC) method and a compressible Navier-Stokes based continuum method are used to investigate the flow inside micronozzles and to predict the performance of such devices. For the Navier-Stokes approach, both slip and no-slip boundary conditions are applied.
