Condensation problem.?
 
Hi everybody. I have a question...

Can we model the condensation of water vapour in an air flow system on a cool surface using Fluent?

Hi,

This can be done using a surface reaction.An UDF has to be written which sets the surface reaction rate.

Fluent 5.x and 6.x can't solve heterogenous reaction.

and when u use surface reaction u will see result of condensate is strange! coz U must defind condensate to surface species but surface species can't flow out from that surface or u can't see flow pattern of condensate.
May be use Fluent 4.x.
Regard, Thitikorn
