An application of the extended corresponding state model to thermodynamic property calculations for trans-1,3,3,3-tetrafluoropropene [HFO-1234ze(E)].

Résumé

A new thermodynamic property model is presented for trans-1,3,3,3-tetrafluoropropene [trans-CHF=CHCF3, HFO-1234ze(E)] based upon available experimental data. This model is an application of the extended corresponding state principle, which is one approach in property modelling for fluids with limited experimental databases. The model is capable of predicting with reasonable accuracies various properties of HFO-1234ze(E), including the PVT relation, energies, heat capacities, and vapour-liquid equilibrium. The reference fluid of the model is 1,1,1,2-tetrafluoroethane (HFC-134a). Comparisons with experimental data show that typical uncertainties of calculated properties are 0.5 % in the vapour pressure, 0.8% in the liquid density, and 2.5% in the liquid and vapour isobaric heat capacities.
