Considering Humidity in the Air
 

Hi Guys,

I am modelling a building block ( a room ) with Air inside for Natural Convection. I wonder If anyone knows how can I consider the impcat of Air humidity in the model?


Cheers,

Hi,

You need to find a database, that contains all relevant physical properties of air as a function of humidity. Then, you can put these values into fluent (Materials->Fluid->Air->....).
You will need viskosity, specific heat capacity, density, thermal conductivity and whatever your model needs.

I think you should use Species to model the humidity in the air. Knowing mass fraction of water-vapor at room and solving set of N-S equations plus an additional equation for water-vapor.
Goodluck

hi ariya, i'd like to know what have you done with your work? did you find how to simulate it?? i'm simulating thins kind ,i was wondering if you could show me please thx
