Summary

Due to concerns about global warming, there is interest in 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) as potential replacements for refrigerants with high global warming potential (GWP). In this paper we survey available data and provide viscosity correlations that cover the entire fluid range including vapor, liquid, and supercritical regions. The correlation for R1234yf is valid from the triple point (220?K) to 410?K at pressures up to 30?MPa, and the correlation for R1234ze(E) is valid from the triple point (169?K) to 420?K at pressures up to 100?MPa. The estimated uncertainty for both correlations at a 95% confidence level is 2% for the liquid phase over the temperature range 243?K to 363?K at pressures to 30?MPa, and 3% for the gas phase at atmospheric pressure.
