Respected Sirs/Ma'am,
I am trying to simulate heat transfer coefficient of super-critical water in fluent. Geometry is simple tube with constant heat flux applied at wall operating at 24.1 M Pa. I used NIST real gas model with "water.fld" file and the results got not converged and also fine refpro error 203. i used mass flux inlet with 24.52 M Pa and pressure outflow condition.
Can anyone help me to resolve my problem that how to use this model more efficiently and accurately?
Thanks a lot.
Best Regards
Santosh Kumar Rai
Why not using IAPWS-IF97 water/water steam properties in CFX, which come with CFX out-of-the-box and which are covering supercritical conditions as well? CFX, in my honest opinion, is more stable for complex multiphase flows in any case in comparison to Fluent.

Giuseppe Bianchi i am trying to import properties by same method but still i am getting refpro error every time. So please tell me how can i resolve my error?
