Surface tension measurement and modeling work for new low GWP working fluids.
Number: pap. n. 59
Author(s) : KONDOU C., ABBADI J. el, HOURIEZ C., et al.
Summary
In this work, the surface tensions of some selected new low GWP (global warming potential) refrigerant mixtures containing HFOs (hydrofluoroolefins) were determined. The surface tension of the HFO-1123/HFC-32 was experimentally determined at temperatures from 265 K to near the critical points and with various compositions. Further, a model associating a cubic equation of state with the linear gradient theory was developed. Good agreement was observed between the experimentally obtained results and those obtained using the developed model.
