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 states principle, which is one approach in property modelling for fluids with limited experimental databases. The model is capable of calculating 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 of calculated values using the model are made with experimental data. Typical uncertainties of calculated properties are 0.2% in the vapour pressure, 0.5% in the liquid density, and 5% in the liquid and vapour isobaric heat capacities. In addition, an ancillary equation is given for the vapour pressure. Thermodynamic property diagrams generated using the model are also provided.
