moist air in CFX
 

Hi,

I am modelling particles curtains using EL-EL approach in CFX. I was wondering how can I consider the humidity of air. I have relative humidity and I know I can calculate mass fraction of water but I don't know how can I put it in Pre-CFX.

Thank's

u got answer?

The simplest way to track humidity is by using an additional variable. A more accurate and more complex way is to use a multicomponent mixture and model the humidity as a mass fraction.
