Measurement and Correlation of the Thermal Conductivity of 1,1,1,2,2,3,3-heptafluoro-3-methoxypropane (RE-347mcc)



Richard A. Perkins, Marcia L. Huber, Marc Assael


New experimental data for the thermal conductivity of 1,1,1,2,2,3,3-heptafluoro-3-methoxypropane (RE-347mcc, HFE-7000) are reported for vapor, liquid, and supercritical states. These new experimental data were obtained with transient hot-wire apparatus over the temperature range from 162 K to 500 K and at pressures from 0.04 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 kgm-3), 1.5 % for vapor and supercritical regions (pressures  1 MPa and densities < 200 kgm-3), 3 % for supercritical states (200 kgm-3  densities  600 kgm-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 % to 4.2 % that depends upon the temperature and pressure, with larger uncertainties in the critical region.
