Hi

If you do not specify the boundary as anything, then it will automatically be classified as a default interior by fluent. This will mean that heat will transfer across the boundary anyway.

Hi!

I don't really understand your problem. You have a liquid sphere (drop) in some other fluid (like air).

I think in this case you should use the VOF multyphase model. In this case you specify the liquid droplet position dirrectly in Fluent...

Best regards

Hi!

I currently don't have accsess to fluent or to fluent documentation to tell you directlly. I think you should go trough tutorial for VOF which is in fluent documentation. Bassically you define a certain region (for example a box from x=0 to x=1, y=0 to y=1 and z=0 to z=1)in fluent and then set is as water. Everithing else in your domain is considered as air...I hope this helps - but i'm shure you'll understand what I mean when you go torough tutorial..

Good luck

MATEUS
