New experimental data for the thermal conductivity of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone (Novec 649) are reported for vapor, liquid, and supercritical states. These new experimental data were obtained with a transient hot-wire apparatus over the temperature range from 183 to 501 K and at pressures from 0.02 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% that depends upon the temperature and pressure, with larger uncertainties in the critical region.

报告了 1,1,1,2,2,4,5,5,5-九氟-4-(三氟甲基)-3-戊酮 (Novec 649) 蒸气、液体和超临界热导率的新实验数据州。这些新的实验数据是通过瞬态热线装置在 183 至 501 K 的温度范围和 0.02 至 69 MPa 的压力下获得的。这些数据用于开发蒸气、液体和超临界流体的热导率的广泛相关性。此处报告的实验数据对于液体和超临界区域（密度 >600 kg·m –3 ）不确定性为 1%，对于蒸汽和超临界区域（压力 ≥1 MPa 且密度 <200 kg·m –3 ）不确定性为 1.5% ，超临界状态（200 kg·m –3 ≤ 密度 ≤ 600 kg·m –3 ）为 3%，蒸气和超临界状态（压力 <1 MPa）为 3%。这项工作中开发的热导率相关性估计具有扩大的相对不确定性，置信度为 95%，范围约为 1% 到 4%，具体取决于温度和压力，关键区域的不确定性更大。
