摘要

国际水和蒸汽性质协会最近采用了一种新的重水热力学性质公式。本文描述了重水粘度的新配方的开发，该配方与新的状态方程一致，适用于775 K和960 MPa的流体状态，根据状态点的不同，不确定度在1%至5%之间。与实验数据和以前的粘度公式进行了比较。新配方包含在临界点附近的一个小区域内提高粘度的术语，这些术语在以前的配方中没有包含。与以前的相关性相比，新的公式适用于更广泛的条件。

New International Formulation for the Viscosity of Heavy Water

The International Association for the Properties of Water and Steam has recently adopted a new formulation for the thermodynamic properties of heavy water. This manuscript describes the development of a new formulation for the viscosity of heavy water that is consistent with the new equation of state and is valid for fluid states up to 775 K and 960 MPa with uncertainties ranging from 1% to 5% depending on the state point. Comparisons with experimental data and with a previous viscosity formulation are presented. The new formulation contains terms for the enhancement of viscosity in a small region near the critical point that were not included in previous formulations. The new formulation is applicable over a wider range of conditions than previous correlations.

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.
