Default Vof, udf and mass transfer panel
Posts: n/a
Hi... thanks all of you for your help, every time... Please read my bad English and help me....

I have to solve the mass transfer problem in vof model. I need some help about the mass treansfer function in the phase interaction panel.

What is the mass transfer function(mtf) in the phase interaction panel in Fluent. Using the udf, what should I difine in the mtf panel? Is it just the mass transfer coefficient or a kind of equation? What is the request condition to use this panel?

Can I define the duffusivity as a function in the VOF model by using the UDF? And, when the liquid such as alcohol diffuses into the air, Can I define the mass transfer function by using the equation including the diffusity?

Thanks in advance.
