Multicomponent Condensation
 

Dear All,

I am going to solve the multi-component condensation. I already wrote the code for multi-component mass transfer in the presence of K-value at the boundary. I am wondering if condensation is the same thing here which can model with differing K-value at different temperature and pressure.
Besides that, I am wondering how someone would model the condensation of steam in the presence of other condensable gases.
My main problem is that I cannot formulate the problem in terms of boundary conditions and source terms. Any brainstorming is appreciated .

P.S. I already asked this question in OpenFoam forum but I want to know how other softwares and/or resources can handle this problem
