Aliebadi is on a distinguished road
I want to simulate stratified flow of steam and water with CFX in 2-D rectangular geometry. For interfacial heat transfer coefficient, the below correlation was advised:

NU=C . Re (liquid) m. Re (vapor) n.Pr

I have defined two fluid vapor and water, but I don’t know how define the expression in CCL for this correlation. in the other word the main challenge is

the definition of Reliquid and Re vapor in CCL subroutine. Who can help me?
