Abstract
New experimental data for the thermal conductivity of cis-1,1,1,4,4,4-hexafluoro-2-butene (R1336mzz(Z)) are reported for vapor, liquid and supercritical states. These data were obtained with transient hot-wire apparatus over the temperature range from 192 K to 498 K and at pressures from 0.05 MPa to 69 MPa. These data were used to develop a wide-range correlation for the thermal conductivity of the vapor, liquid, and supercritical fluid. The experimental data reported here have an uncertainty of 1 % for the liquid and supercritical regions (densities > 600 kgm-3), 1.5 % for vapor and supercritical regions (pressures 1 MPa and densities < 200 kgm-3), 3 % for supercritical states (200 kgm-3 densities 600 kgm-3), and 3 % for vapor and supercritical states (pressures < 1 MPa). The thermal-conductivity correlation developed in this work is estimated to have an expanded relative uncertainty, at a 95 % confidence level, ranging from approximately 1.4 % to 4.2 % depending on the temperature and pressure, with larger uncertainties in the critical region.Citation
