Hi!
I'm writting my master's thesis and need to simulate R-245fa as a real gas in Ansys CFX.
I have all properties from NIST, but I still need the fourth order polynomial of specific heat at constant pressure. I have tried unsuccessfully to calculate a regression by using points of the same pressure in p-h diagram, but it did not work, because went out of range when iterating.
I also paid attention not to forget to divide the universal gas constant...

I would be very pleased if someone ever simulated R-245fa and could tell me with coefficients to use!

Thank you very much!
