Thermophoresis in Rarefied Gas Flows
Aerosol Science and Technology, 2002Numerical calculations are presented for the thermophoretic force acting on a free-molecular, motionless, spherical particle suspended in a rarefied gas flow between parallel plates of unequal temperature. The rarefied gas flow is calculated with the direct simulation Monte Carlo (DSMC) method, which provides a time-averaged approximation to the local ...

Rarefied-Gas Flow in the Knudsen Layer
The Physics of Fluids, 1968Discrete ordinate method has been applied to the Bhatnagar-Gross-Krook model to analyze the velocity field in the Knudsen layer. An exact relation between the macroscopic velocity at the plate and the shear stress has been obtained. The method also provides accurate numerical results for quantities of interest such as slip coefficient.

Plane Poiseuille Flow of a Rarefied Gas
The Physics of Fluids, 1968An analytical solution to the problem of rarefied gas flow in a channel is obtained by the moment method. The expected minimum in volume flow rate is found; the flow rate exhibits an algebraic instead of a logarithmic singularity at low pressures. Present results are compared with the results from other theories and with measurements.

Higher-order effects in rarefied channel flows
Physical Review E, 2008The regularized 13 moment (R13) equations and their boundary conditions are considered for plane channel flows. Chapman-Enskog scaling based on the Knudsen number is used to reduce the equations. The reduced equations yield second-order slip conditions, and allow us to describe the characteristic dip in the temperature profile observed in force driven ...

Thermophoresis in Rarefied Gas Flows
AIP Conference Proceedings, 2003Numerical calculations are presented for the thermophoretic force acting on a motionless, spherical particle suspended in a quiescent, rarefied gas between parallel plates of unequal temperature. The rarefied‐gas heat flux and temperature profiles are calculated with the Direct Simulation Monte Carlo (DSMC) method, which provides a time‐averaged ...

Computation of Transitional Rarefied Flow
1991Rarefied flows around reentry vehicles can be evaluated by using a Monte-Carlo numerical simulation. Results for Hermes vehicle are presented and agree fairly well with wind-tunnel data.

Simulation of rarefied vapor flows
Industrial & Engineering Chemistry Research, 1991The vapor region between evaporator and condenser surfaces of different areas is examined by direct Monte Carlo simulation of multicomponent, high-vacuum distillation. Vapor profiles change sharply through the kinetic layer next to the evaporator and again through that next to the ...

Flow of Rarefied Gas over Plane Wall
The Physics of Fluids, 1970Flow of rarefied gas over an infinite plane wall on the basis of a relaxation model of the Boltzmann equation is considered. The solution is obtained in the form: Hilbert solution and boundary layer term which is appreciable only in a thin layer (with thickness of order of the mean free path) adjacent to the boundary.
