Rarefied Gas Flows in Micro-Channels [PDF]
AIP Conference Proceedings, 2003 Rarefied gas flows through micro‐channels are simulated using particle approaches, named as the information preservation (IP) method and the direct simulation Monte Carlo (DSMC) method. Some important issues such as mass‐flux convergence in IP calculations and the tangential momentum accommodation coefficient along micro‐channel surfaces in experiment ...

An open source, parallel DSMC code for rarefied gas flows in arbitrary geometries [PDF]
, 2010 This paper presents the results of validation of an open source Direct Simulation Monte Carlo (DSMC) code for general application to rarefied gas flows. The new DSMC code, called dsmcFoam, has been written within the framework of the open source C++ CFD ...

Rarefied gas flow in functionalized microchannels. [PDF]
Sci Rep, 2023 AbstractThe interaction of rarefied gases with functionalized surfaces is of great importance in technical applications such as gas separation membranes and catalysis. To investigate the influence of functionalization and rarefaction on gas flow rate in a defined geometry, pressure-driven gas flow experiments with helium and carbon dioxide through ...

Comparing macroscopic continuum models for rarefied gas dynamics : a new test method [PDF]
, 2006 We propose a new test method for investigating which macroscopic continuum models, among the many existing models, give the best description of rarefied gas flows over a range of Knudsen numbers.

Data-driven nonlinear constitutive relations for rarefied flow computations
Advances in Aerodynamics, 2021 To overcome the defects of traditional rarefied numerical methods such as the Direct Simulation Monte Carlo (DSMC) method and unified Boltzmann equation schemes and extend the covering range of macroscopic equations in high Knudsen number flows, data ...

Rarefied gas flow through a slit.
SHINKU, 1990 A rarefied gas flow through a slit in an infinite plane wall, induced by a small pressure difference across the slit, is studied on the basis of the kinetic theory. The system of integral equations for the macroscopic variables (the velocity, density, and temperature of the gas), derived from the linearized Boltzmann–Krook–Welander equation with the ...

A topology optimization method for rarefied gas flows
Nihon Kikai Gakkai ronbunshu, 2017 We construct a topology optimization method for two dimensional rarefied gas flow problems, based on level-set boundary expressions. The degree of rarefaction is expressed by the Knudsen number, which is the ratio of the mean free path and the ...
