“…A total of 2890 experimental values of mixtures composed by the investigated pure components were available from the TDE database and the latest publications. − These mixtures include 24 binary mixtures, two three-component mixtures, and one five-component mixture. Some mixtures are complex systems including very different components, such as alkane + haloalkane and CO 2 + haloalkane.…”

The residual entropy scaling of viscosity was applied to pure refrigerants, including natural refrigerants, hydrofluoroolefins, hydrochlorofluoroolefins, perfluorocarbons, hydrofluorocarbons, chlorofluorocarbons, and hydrochlorofluorocarbons and their mixtures. Experimental temperature, pressure, and viscosity data of 39 pure refrigerants, including more than 15,000 experimental data values from more than 400 literature sources, were used to build a univariate correlation function between the reduced residual viscosity and the dimensionless residual entropy. The correlation function contains only four fitted parameters and a fluid-specific scaling factor. Approximately, 80.0% of the experimental data are predicted within 5.0% when the fluid-specific fitted parameters are used. About 80.0% of the experimental data collapse onto one single curve within 7.9% when the global fitted parameters and the fluid-specific scaling factor were adopted for the correlation function. The correlation function is able to predict mixture viscosity without any additional empirical parameters. Approximately, 80.0% of the experimental data of 27 binary or multi-component mixtures composed by the investigated pure components, encompassing 2890 experimental values from more than 20 literature sources, agree with the correlation function within 7.9%, which is as good as the comparison for pure fluids. The commonly used extended corresponding states model has as many as four more parameters for each pair of components and has been optimized for some of the binaries; therefore, it generally yields better agreement than the proposed correlation function for binary mixtures but similar performance for multi-component mixtures.

“…The DLS apparatus was already employed in our former investigation for thermophysical properties of refrigerants. ,, The experimental system includes a diode-pumped solid state laser (Spectra-Physics Excelsior, 300 mW) with a wavelength of λ 0 = 532 nm, a digital correlator with a single-tau structure (ALV-LinCorr) for the computation of the pseudo-cross-correlation function, optical path, and sample cell (stainless steel and equipped with quartz windows: i.d., 70 mm; vol., 160 cm 3 ). The incident angle was adjusted by a rotation table (DaHeng, GCD-011080) with a standard uncertainty of 0.05% ( k = 2).…”

In this work, we have studied the thermal diffusivity of saturated liquids in the temperature range from 303.15 to 393.15 K for trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E)) and dodecafluoro-2-methylpentan-3-one (Novec1230) by the dynamic light scattering method. The relative combined uncertainties of thermal diffusivity were estimated to be 3%. The liquid thermal diffusivity was correlated with a simple polynomial equation. The deviations between our experimental results and the correlation are less than 2.11%, and in most cases those were within 1%.

The temperature of the cell is regulated through resistance heating and measured by two calibrated 100 Ω platinum resistance probes with a total uncertainty of 0.03 K.

A surface light scattering (SLS) method was applied to investigate the saturated liquid dynamic viscosity and surface tension of trans-1-chloro-3,3,3-trifluoropropene (R1233zd(E)) and dodecafluoro-2-methylpentan-3-one (also known as Novec1230 and Novec649) at a temperature range from 303 to 403 K and 303 to 433 K, respectively. The typical expanded uncertainty (k = 2) of the saturated liquid dynamic viscosity and surface tension is 3% and 1.5%, respectively. The liquid viscosity and surface tension were correlated with a simple polynomial equation and van der Waals equation, respectively.
