Hi all, got an annoying problem here. I started looking into CFD because I want to model particles in a low pressure flow. After doing some research I've found that the Knudsen number of the flow is somewhere between 1 and 10, which is a difficult area to solve. Does anyone know of any programs or methods that can solve in this regime?
Thanks |

I'm currently investigating in the same field. So although I'm looking for answers myself, I can give you a short list of methods and implementations that look at least promising:
Hope that helps. |

Thanks for the reply Christian. I also found this paper which outlines some method for studying rarefied gas flow, http://www.nist.gov/data/PDFfiles/jpcrd540.pdf.
I'm currently using Star-CCM+ to study the particles in the continuum regime. This should help me find the best way to continue with my problem. |

Thanks for the link to the paper. Since I want to study the gas flow through apertures it is very helpful.
