Knudsen Number contours and ANSYS Fluent ?

boryan1965 · January 30, 2012, 16:31

Hello everyone,

I wonder

whether there is way to depict contours of Knudsen Number in Fluent 12.xx in same fashion as contours of velocity, density etc...

I need this for a micro nozzle jet flow I aim to simulate...

Thank you in advance. You reply will be highly appreciated.

Kind regards,
Boryan

You'll have to create a custom field function for the Knudsen number. The formula that will be most usefull is Kn prop to Mach number/Reynolds number.
