Measurement and Correlation of the Thermal Conductivity of 1,1,1,2,2,4,5,5,5-Nonafluoro-4- (trifluoromethyl)-3-pentanone



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


New experimental data on the thermal conductivity 1,1,1,2,2,4,5,5,5-Nonafluoro-4- (trifluoromethyl)-3-pentanone (Novec 649, Novec 1230) are reported that allow the development of wide-range correlations. These new experimental data, covering a temperature range of 183 K to 501 K at pressures from 0.02 MPa to 69 MPa, are used to develop a correlation for the thermal conductivity. The experimental data reported here have an uncertainty of 1 % for liquid and supercritical (density > 600 kg.m-3), 1.5 % for vapor and supercritical (pressure < 1 MPa and density < 200 kg.m-3), 3 % for supercritical (200 kg.m-3 < density < 600 kg.m-3), and 3 % vapor and supercritical (pressure < 1 MPa). Based on the uncertainty of and comparisons with the present data, the thermal-conductivity correlation is estimated to have a relative expanded uncertainty ranging at a 95 % confidence level from approximately 1 % to 4 % depending on the temperature and pressure, with larger uncertainties in the critical region.
