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.

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 ...

On the modelling of isothermal gas flows at the microscale [PDF]
, 2008 This paper makes two new propositions regarding the modelling of rarefied (non-equilibrium), isothermal gas flows at the micro scale. The first is a new test case for benchmarking high-order, or extended, hydrodynamic models for these flows.
