Summary

The trans-1,1,1,4,4,4-hexafluoro-2-butene (R1336mzz(E)) would be a novel working fluid in the heat pumps and organic Rankine cycles with low-GWP value, lower toxicity, and non-flammability. The transport property mainly thermal conductivity measurement is the main target of the paper for this HFO refrigerant for the liquid, vapor, and supercritical states, respectively. Simple correlations at saturated state are developed to estimate the thermal conductivity for industrial design and simulation. In this article, the thermal conductivity data were reported in the temperature from 313 to 393 K over the pressure until 4.0 MPa and temperature from 313 to 453 K at pressure up to 2.5 MPa both for liquid and vapor states, respectively. Also, the thermal conductivity in a supercritical region was recorded from temperature range 413 to 453 K and pressures at 3.0 to 4.0 MPa. The experimental liquid and vapor thermal conductivity data of R1336mzz(E) were compared with the data measured for cis-1,1,1,4,4,4-hexafluoro-2-butene (R1336mzz(Z)). Moreover, the correlations at the saturated state were developed by extrapolating the experimental data until the saturation conditions both for liquid and vapor states. The estimated combined uncertainties for the liquid, vapor and supercritical regions of thermal conductivity measurement were recorded to 1.94 %, 1.98 %, and 2.01 %, respectively.
