Résumé

The study presents the surface tension measurement data of HFO-1123 and HFO-1234ze(E) with global warming potential (GWP) of less than 1 and of binary mixtures HFO-1123/HFC-32 and HFO-1234ze(E)/HFC-32. The capillary constant and surface tension of the fluids are measured across temperatures in a range of 267 K to 307 K with a differential capillary rise with a propagated uncertainty of ±0.23 mN m-1. Among the selected predicting methods, the correlations of DiNicola et al. (2018) exhibit the best agreement to the measured surface tension of both HFO-1123 and HFO-1234ze(E). In order to predict the surface tension HFO-1123/HFC-32 and HFO-1234ze(E)/HFC-32, empirical correlations are proposed based on the measured data.
