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 ...

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.

Effects of the Wall Temperature on Rarefied Gas Flows and Heat Transfer in a Micro-Nozzle
Micromachines, 2023 When the satellite is in orbit, the thruster will experience drastic temperature changes (100–1000 K) under solar radiation, which will affect the rarefied gas flow state in the micro-nozzle structure of the cold gas micro-thruster.

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 ...

DSMC–LBM mapping scheme for rarefied and non-rarefied gas flows [PDF]
Journal of Computational Science, 2016 We present the formulation of a kinetic mapping scheme between the Direct Simulation Monte Carlo (DSMC) and the Lattice Boltzmann Method (LBM) which is at the basis of the hybrid model used to couple the two methods in view of efficiently and accurately simulate isothermal flows characterized by variable rarefaction effects. Owing to the kinetic nature
