Résumé

As one of hydrofluoroolefins, trans-1,1,1,4,4,4-hexafluoro-2-butene (R1336mzz(E)) is treated as a novel working substance for organic Rankine cycles as well as heat pumps for its low GWP, non-flammability, and lower toxicity. The objectives of this study are the viscosity measurement for R1336mzz(E) in liquid, vapor, and supercritical regions by the method of tandem capillary tubes and the development of correlations for the saturated liquid and vapor viscosities. The viscosity measurements for R1336mzz(E) were conducted over the range of temperature from 314 to 394 K for the liquid, 391 to 453 K for the vapor, and 413 to 453 K for the supercritical region, respectively, at pressures from 1.0 to 4.0 MPa. The expanded uncertainties in the viscosity measurement are calculated as 2.26 % for liquid, 2.30 % for vapor, and 2.32 % for supercritical phase using k=2 and 95 % confidence level. The experimental data are correlated with the ECS model; the AAD is 5.04 % for the liquid, 22.19 % for the vapor, and 11.88 % for the supercritical phase, respectively. The saturated viscosities are also estimated by the extrapolation from the measurements to the liquid-vapor saturation conditions. For industrial design and simulation, simple correlations are developed in terms of the saturation temperature to predict the viscosities of the saturated liquid and vapor phases, respectively.
