Résumé
This is the 12 slide PowerPoint presentation of Kondou and Higashi's paper on surface tension measurement for low GWP refrigerants. By a differential capillary rise method, liquid-vapor interface surface tension was measured for new candidates of next generation refrigerant HFO-1123 and HCFO-1224yd(Z) at temperatures from 266 K to 304 K and from 266 K to 340 K, respectively. The repeatability and reproducibility of the measurement method were checked with HFC-134a and HFC-32. The propagated uncertainty in surface tension was estimated to be within ±0.2 mNm-1. Based on the measured data, the Van der Waals type empirical correlations were proposed for HFO-1123 and HCFO-1224yd(Z), those are associated with the critical temperatures reported by Higashi and Akasaka. These empirical correlations agree with the measured surface tension data within the measurement uncertainty in the tested temperature range.
