This paper presents a new wide-ranging correlation for the thermal conductivity of ammonia based on critically evaluated experimental data. The correlation is designed to be used with a recently published equation of state that is valid from the triple-point temperature to 680 K and pressures up to 80 MPa. We estimate the uncertainty at a 95% confidence level to be 6.8% over the aforementioned range, with the exception of the dilute-gas range where the uncertainty is 4% over the temperature range 285 K–575 K. The uncertainties will be larger outside of the validated range and also in the critical region.

从三点温度到 680 K 和压力高达 80 MPa 的氨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氨热导率相关性。该相关性旨在与最近发布的状态方程一起使用，该状态方程在三相点温度至 680 K 和压力高达 80 MPa 的范围内有效。我们估计上述范围内 95% 置信水平的不确定性为 6.8%，但稀释气体范围除外，在 285 K–575 K 的温度范围内不确定性为 4%。在验证范围内，也在临界区域内。
