R1234yf_mh
R1234yf_mh provides approximate thermodynamic and transport property data for HFO-1234yf (2,3,3,3-tetrafluoropropene, MW 114.04116 g/gmole). The thermodynamic properties were fitted to the Martin-Hou equation of state using property information published in the following papers:

Note that the liquid phase is assumed to be incompressible in this formulation. Enthalpy and entropy values are referenced to 200 kJ/kg and 1 kJ/kg-K respectively for saturated liquid at 273.15 K.
Transport properties are estimated using extended corresponding states as described in:
Klein, S.A., McLinden, M.O., Laesecke, A., An Improved Extended Corresponding States Method for Estimation of Viscosity of Pure Refrigerants and Mixtures, International Journal of Refrigeration, Vol. 20, No. 3, 1997, pp. 208-217
