nh.cryo is on a distinguished road
Hello All,
I am interested in simulating problems relating supercritical fluids (single phase, near the critical point) using ANSYS-FLUENT V16. The thermo-physical properties are a strong function of fluid pressure and temperature near this state. So, I plan to provide either a surface fit or a 2D Table look-up in the form of x = f(p, T); where x is the thermo-physical property in question.

In the past, I have used user-defined variable properties (density, viscosity, thermal conductivity, specific heat, drho/dp etc.) with ESI CFD-ACE+ (a SIMPLEC based solver). Not sure, how it's done (if possible at all) in FLUENT. I have checked the CFD-Online forum for this issue, but it appears to me that there is an issue related to specifying the specific heat.

Any help in this matter will be greatly appreciated.
