Is the simulation equipped with tools to handle the conditions in which the mean free path of gas particles is the same order as the wavelength ? (knudsen number ~ 1)
If so, how can I control the pressure in a homeganous medium to see the change in behaviour of the sound wave?

Hi tomk2006,
k-Wave solves a form of the conventional conservation equations derived assuming a continuum hypothesis. This won't apply in your case, and you'll instead need to look towards statistical mechanics and the kinetic theory of gases. I don't know much about this I'm afraid.
Hope that helps,
Brad.

Thank you, I will use the k-Wave simulation to analyze a different part of my experiment.
