hi all..

I am new user of cfd-fluent...I am working on heat exchanger model..where air heat absorber and alumenium as wall at higher temperature..my problem is, I assume that water droplets may form on fins(al). I want to model water(drops) zone on fins in gambit. I am using fluent 6.0 .Should i mesh the water droplets? what type of boundary condition should use? need of any continuum type to specify?

please, if my question is not clear....ask me.

thanks in advance

You dont need to create mesh for water droplets. Just mesh your fin and wall. Then use either DPM model or other Multi phase models to simulate the water droplets.

thanku very much for ur response

thing is if I dont mesh water droplets the wall(fin boundary) which shares with droplets cold not export to the fluent. if i stll could not explain it clerly, please allow me to give mail to mail id...so that i can send a simple model to u thanking u...
