Multiphase flow!
 
Hey, I'm doing a study on cavitation around a propeller using fluent and I'm trying to use a multiphase flow (water liquid and water vapor). I checked fluent's tutorials about cavitation and they said that I should have two inlets (Inlet 1 as liquid and Inlet 2 as vapor) but in Gambit when I defined Inlet 1 and Inlet 2 on the same inlet face boundary, fluent wasn't able to see both inlets and it shows only 1 inlet... what should I do to define a multiphase flow??

Please help!

Hi!

I don't think you have to define liquid and vapor inlet for cavitation simulation... Cavitation in Fluent can be a problem but in latest versions it work fine if you know a few tricks. I did most of simulations in Fluent 6.1 and unsteady. If you want some papers where I described what I did you can send me an e-mail. There was also a article about my work in Fluent-News (fall 2004 issue - I'm not sure).

hi
i'm working on the marine propeller together with sheet cavitation and of coure hase some problem to capture it correctly, please send me your investigates for seting up FLUENT and your advises(davidmurphy26@ymail.com)
sincerly your
