This paper presents a new wide-ranging correlation for the thermal conductivity of n-hexadecane based on critically evaluated experimental data. The correlation is designed to be used with a recently published equation of state, and it is valid from the triple point up to 700 K and pressures up to 50 MPa. We estimate the uncertainty at a 95% confidence level to be 4% over the aforementioned range, with the exception of the dilute-gas range where the uncertainty is 2.7% over the temperature range 583 to 654 K. The correlation behaves in a physically reasonable manner when extrapolated to the full range of the equation of state, but the uncertainties are larger outside of the validated range, and also in the critical region.

从三点到 700 K 和高达 50 MPa 的正十六烷热导率的参考相关性

本文基于严格评估的实验数据，提出了一种新的广泛的正十六烷热导率相关性。该相关性旨在与最近发布的状态方程一起使用，它在三相点高达 700 K 和压力高达 50 MPa 的范围内有效。我们估计 95% 置信水平的不确定性在上述范围内为 4%，但稀释气体范围除外，在 583 到 654 K 的温度范围内不确定性为 2.7%。相关性表现为物理上合理外推到状态方程的整个范围时的方式，但不确定性在验证范围之外更大，也在临界区域内。
