Abstract

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680K和压力高达80MPa的氨热导率的参考相关性

本文提出了一个新的广泛的相关性，为热导率的氨基于严格评估的实验数据。该相关性被设计用于最近发布的状态方程，该方程在三相温度至680 K和压力高达80 MPa时有效。我们估计在95%置信水平下的不确定性在上述范围内为6.8%，但稀气范围在285 K - 575 K温度范围内的不确定性为4%。在验证范围之外和临界区域，不确定性会更大。

期刊介绍： The Journal of Physical and Chemical Reference Data (JPCRD) is published by AIP Publishing for the U.S. Department of Commerce National Institute of Standards and Technology (NIST). The journal provides critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation, preferably with uncertainty analysis. Critical reviews may also be included if they document a reference database, review the data situation in a field, review reference-quality measurement techniques, or review data evaluation methods.
