Abstract

Due to concerns about global warming, there is interest a class of fluids known as hydrofluoroolefins (HFO’s) as potential replacements for refrigerants with high global warming potential (GWP). Two such HFO’s are 2,3,3,3-Tetrafluoroprop-1-ene (R1234yf) and trans-1,3,3,3-Tetrafluoropropene (R1234ze(E)). To assist engineers and equipment designers who need thermophysical property models, we survey available data for the viscosity of R1234yf and R1234ze(E) and provide wide-ranging 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. The estimated uncertainty of this correlation at a 95 % confidence level is 3.5 % for the liquid phase at pressures to 30 MPa and 3 % for the gas phase. 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 of this correlation is 3.5 % for the liquid phase at pressures to 30 MPa and 3 % for the vapor phase. Comparisons with the experimental data are given for both fluids.
