A new wide-ranging correlation for the viscosity of xenon, based on the most recent theoretical calculations and critically evaluated experimental data, is presented. The correlation is designed to be used with an existing equation of state, and it is valid from the triple point to 750 K, at pressures up to 86 MPa. The estimated expanded uncertainty (at a coverage factor of = 2) varies depending on the temperature and pressure, from 0.2 % to 3.6 %. A term accounting for the critical enhancement is also included. The correlation behaves in a physically reasonable manner when extrapolated to 200 MPa, however care should be taken when using the correlations outside of the validated range.
基于最新的理论计算和经过严格评估的实验数据，提出了一种新的、适用范围广泛的氙气粘度关联式。该关联式旨在与现有的状态方程一起使用，在压力高达86 MPa的情况下，从三相点到750 K均有效。估计的扩展不确定度（包含因子k = 2）随温度和压力的变化而变化，范围为0.2%至3.6%。还包括一个考虑临界增强的项。当外推至200 MPa时，该关联式的表现符合物理合理性，但在验证范围之外使用该关联式时应谨慎。
