“…Before the test fluid viscosity measurements, the reliability of the experimental apparatus should be checked. , In this study, R134a was used as a reference fluid to confirm the reliability and stability of the measurements. The viscosity of R134a was measured at temperatures from 313 (39.85 °C) to 356 K (82.85 °C), and pressure of 1.70 to 4.16 MPa at liquid phase.…”

The principal goals of the present work are to measure the viscosity of vapor and liquid cis-1,1,1,4,4,4-hexafluoro-2-butene (R-1336mzz(Z)) and propose simplified correlations of the extracted data under saturation conditions for industrial design and simulation. R-1336mzz(Z), a hydro-fluoro-olefin with a low global warming potential and attractive environmental properties, can be considered as a potential working fluid for high-temperature heat pumps and organic Rankine cycles. Nevertheless, reliable experimental R-1336mzz(Z) viscosity data are lacking. This study presents R-1336mzz(Z) viscosity data measured by a tandem capillary tube method at temperatures from 314 (40.85 °C) to 434 K (160.85 °C) and 375 (101.85 °C) to 475 K (201.85 °C) for liquid and vapor phases, respectively, at pressures up to 4.06 MPa. Total standard uncertainties in liquid and gas viscosity measurements were lower than 3.04 and 3.21%, respectively.

The isobaric heat capacity of 2,3,3,3-tetrafluoropropene (R1234yf) was studied in the compressed liquid and supercritical phases. A total of 154 experimental data were acquired for eight isotherms from 303.68 to 373.31 K in the pressure range of 1.5 to 12 MPa. The experimental values of the heat capacity were compared with the literature data. Additionally, the present data were correlated with an empirical equation. The published experimental data sets of thermophysical properties for R1234yf were also summarized in this paper.

“…We estimated the uncertainty of the R1234yf correlation in the liquid phase at pressures up to 30 MPa to be 2 % at a 95 % confidence level over the temperature range 243 K to 363 K, based on the data of Meng et al (Meng et al, 2013). In the gas phase, the best measurements are those of Dang et al (Dang et al, 2015b) The correlation represents this set to within 3 %; there is much more scatter in the Yamaguchi data (Yamaguchi et al, 2009). Additional comparisons are available in Supplemental Information.…”

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 manuscript 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.
