This paper presents new wide-ranging correlations for the viscosity and thermal conductivity of ethyl fluoride (R161) based on critically evaluated experimental data. The correlations are designed to be used with a recently published equation of state that is valid from 130 K to 450 K, at pressures up to 100 MPa. The estimated uncertainty at a 95% confidence level is 2% for the viscosity of low-density gas (pressures below 0.5 MPa), and 3% for the viscosity of the liquid over the temperature range from 243 K to 363 K at pressures up to 30 MPa. The estimated uncertainty is 3% for the thermal conductivity of the low-density gas, and 3% for the liquid over the temperature range from 234 K to 374 K at pressures up to 20 MPa. Both correlations may be used over the full range of the equation of state, but the uncertainties will be larger, especially in the critical region.

氟化乙酯 (R161) 的粘度和导热系数的相关性


本文基于严格评估的实验数据，提出了氟乙烷 (R161) 的粘度和导热系数的新的广泛相关性。这些关系式设计用于与最近发布的状态方程一起使用，该状态方程在 130 K 至 450 K 范围内有效，压力高达 100 MPa。对于低密度气体（压力低于 0.5 MPa）的粘度，在 95% 置信水平下的估计不确定性为 2%，对于在 243 K 至 363 K 的温度范围内、压力高达30兆帕。在 234 K 至 374 K 的温度范围内，压力高达 20 MPa 时，低密度气体的热导率的估计不确定性为 3%，液体的热导率的估计不确定性为 3%。这两种相关式都可以在整个状态方程范围内使用，但不确定性会更大，特别是在临界区域。
