(Versions previous to 12.009 used the equation of state reported in:

The correlation is valid for temperatures in the range between 122.35 K and 430K for pressures less than 35 MPa.  Enthalpy and entropy values are referenced to 200 kJ/kg and 1 kJ/kg-K, respectively for saturated liquid at 273.15 K.

 

Viscosity and thermal conductivity have been estimated using a corresponding states approach with propane as the reference fluid as suggested in:

Klein, S.A., McLinden, M.O., and Laesecke , A., "An improved extended corresponding states method for estimation of viscosity of pure refrigerants and mixtures'

Int. J. of Refrigeration, 20, pp. 208-217, 1997

 

McLinden et al., "An extended corresponding states model for the thermal conductivity of refrigerants and refrigerant mixtures",

Int. J. of Refrigeration, 23, pp. 43-63, 2000

 

The estimated transport data using these methods agrees within 10% compared to measurements reported in:

"Saturated liquid kinematic viscosity, surface tension and thermal diffusivity of two low-GWP refrigerants 3,3,3-trifluoropropene (R1243zf) and trans-1-chloro-3,3,3-trifluoro-1-propene (R1233zd(E)) by light scattering method"
