Novec649

 

Novec649 is a trade name.  However, it is used here for brevity to indicate fluid 1,1,1,2,2,4,5,5,5-Nonafluoro-4-(trifluoromethyl)-3-pentanone (CAS No. 756-13-8, Molar Mass=316.0444).  Property data for this fluid are provided using the Fundamental Equation of State presented in:

J. Chem. Eng. Data 2015, 60, 3646-3659

 

The correlation is valid for temperatures in the range between 165 K and 500 K for pressures less than 50 MPa.  Enthalpy and entropy values are referenced to 200 kJ/kg and 1.0 kJ/kg-K, respectively, for saturated liquid at 0C.

 

Transport properties for the liquid are provided using correlations based on data provided by 3M Corporation in:

Note that an older, less accurate formulation for Novec649 properties was provided with fluid name C6_Fluoroketone.  This fluid remains in the database for backward compatibility, but it should no longer be used.
