I want to use DEFINE_PROPERTY macro to define thermal conductivity of fluid. The expression for fluid thermal conducivity is (Kg+additional terms) in which Kg is original thermal conductivity of fluid. I am wondering can I just use C_K_L(c,t) to access Kg and then add additional terms. Finaly I can return (Kg +additional terms) to fluent solver.
However, I am confused about the logic. Can I access thermal conductivity before I even define it?

What is the underlying law behind Kg?

the literature do not make this very clear. Maybe it's constant or calculated by kinetic theory. Personally, I just use kinetic theory to calculate thermal conductivity of single species and use mass weighted average method to yield thermal conductivity of mixture.
