 May 23, 2006, 03:25 How to set 2 phases in Fluent: Mixture & Water #1 JW Guest   Posts: n/a Hi, Can any one help me to set up 2 phases in Fluent? (1) Phase 1= Mixture of Air & water vapour (2) Phase 2= Water Liquid Note: 2 phases are not mix together. Phase one is air (air + water vapour) flow thru pipe Phase 2 is in the air stream but inside of enclosed container (water). Appreciate your help JW

 May 25, 2006, 02:41 Re: How to set 2 phases in Fluent: Mixture & Water #5 JW Guest   Posts: n/a Thanks for your reply. I want to cooldown container which contain water (Temp 30C) using a air stream (Ie mixture of Air and Water vapour DB temp 20C). Container got sheet metal walls. Using Fluent, is it possible to simulate separately and superimpose it? JW

(this may be a trivial suggestion)..since u are only interested in heat transfer by convection from air to the container and then via conduction from container to water, does it help to model the container with water as solid? (giving properties as that of water?). thank you karuna
