Hi
i use multiphase -VOF model, to model the process of condensation. and I want to add some source terms such as mass and energy. The following is the source :

liquid phase: M=0.1*a1*d1*abs((T1-T0)/T0)
vapor phase:M=-0.1*a1*d1*abs((T1-T0)/T0)

where a1 is the volume fraction of vapor, d1 is the density of vapor,T1 is the temperature of vapor, T0 is the saturation temperature .
how could compile the source terms of UDF. Who could help me? Or give me some hints!

thanks in advanced!

Papers on numerical modelling of steam condenser by CHAO ZHANG will be useful. Do refer it.

Do you have this paper? Could you forward a copy to me? I can't find out it in the Internet. My email is iwangchunyu@gmail.com .
Best Reagards!
