“…A total of 15,122 experimental values of the pure fluids were available from NIST ThermoData Engine (TDE) database version 10 and the latest publications. − For these pure fluids, the TDE database contains more than 400 literature sources, details of which are provided in the Supporting Information. The number of the literature sources for each pure fluid are listed in Table , varying from 1 for CF 3 I to 111 for n -hexane.…”

Entropy Scaling of Viscosity—III: Application to Refrigerants and Their Mixtures

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 experimental setup used is presented in Figure , which consists of a vibrating-wire viscometer made by our group, a temperature measurement system, and a pressure measurement system . In our previous work, this viscometer has already been successfully employed for the viscosity measurement of pure refrigerants, such as R245fa, R236fa, R1233zd(E), R1234yf, and R1234ze(E), and refrigerant mixtures, such as R32 + R1234ze(E)/R1234yf , and R22 + R1234ze(E)/R1234yf . Details of the experimental apparatus can be found in our previous work, , so only a brief introduction to the viscometer is given herein.…”

The liquid viscosity measurements of three binary mixtures at nine compositions and one ternary mixture of R134a, R1234yf, and R1234ze(E) were conducted with a vibrating-wire viscometer in the temperature range of (273 to 353) K and at pressures of up to 15 MPa. The combined expanded uncertainty (k = 2) of the measurements was estimated to be 2.3%. Most of the relative deviations between the values from the REFPROP 10.0 and the experimental viscosities were within 2%. To predict the viscosity of the refrigerant mixtures, an extended hard-sphere (EHS) model combined with the mixing rules was developed. It is found that the viscosities for mixtures predicted by the model show good agreement with the experimental measurements, with the relative deviations being almost within 2%.

“…Less data of viscosity for HCFO-1233zd(E) are available due to this refrigerant is newer. Meng et al [9] measured viscosity using a vibrating wire viscometer covering a temperature range from 243 K to 373 K and pressures up to 40 MPa. Based on the accurate experimental data, Meng et al developed a viscosity correlation.…”
