I'm trying to contrast the CFD code CFX, fluent, and Star CD.

Does any know the methods used buy these codes to represent real fluid properties. In particular I'm interested in:

If I have an equation of state for a fluid, either gas, liquid or both, whethet I can implement this in the above codes and by what method.

Thanks

Craig

1)As for CFX you can use RGP (real gas properties) file that represents tables of thermophysical properties of gas dependent on P and T. 2)Or you can use user fortran for specification of properties. 3)Or you can supply points for interpolation. So probably you can go by first to ways. Maybe for starting, RGP files easier. You just need make program for formated output.
