homogeneous binary mixture

I want to model the vaporization of liquid methane to methane vapor. As and when heat is methane liquid, it should get converted to vapor.
If I chose the peng robinson wet refrigerant of methane ch4vl (homogeneous binary mixture) , will I be able to model this phenomenon.
Or should I add, CH4 vapor seperately and CH4 liquid separately.
Which material should I chose?

You load the 3 materials: CH4vl, CH4l, CH4v.

You add fluid to your domain, and select the binary mixture for the material in the fluid, i.e. CH4vl.

Summary: you are modeling the binary mixture as a fluid in the domain. For thermodynamic calculations, the software needs to know the information of each thermodynamic state separately.

Hope the above helps,
