提出了用温度和密度表示的三氟甲烷（R-23）粘度和导热系数的计算模型。该模型基于Eyring的重要液体结构理论。它适用于各种热力学条件，包括稀释气体、液体、饱和蒸汽、饱和液体以及临界和超临界区域。用相同的函数形式表示粘度和导热系数。通过关联选定的实验数据，确定每个模型的常数。R-23的模型计算值与文献数据非常吻合，即在153至570 K（275至1026 R）温度下的粘度，以及在170至433 K（306至779 R）压力高达60 MPa（8700 psia）时的热导率。 相关性的估计精度为粘度±1%，导热系数±2%。单位:双引文:研讨会，ASHRAE交易，第106卷，pt。1.

A model for the calculation of the viscosity and thermal conductivity of trifluoromethane (R-23), expressed in terms of temperature and density, is presented. The model is based on Eyring's theory of significant liquid structure. It is applicable to a wide range of thermodynamic conditions including dilute gas, liquid, saturated vapor, saturated liquid, and critical and supercritical regions. The same functional form was used to represent the viscosity and thermal conductivity. The constants for each model were determined by correlating selected experimental data. The model-calculated values for R-23 agree very well with the literature data for viscosity at temperatures from 153 to 570 K (275 to 1026 R) and for thermal conductivity at 170 to 433 K (306 to 779 R) at pressures up to 60 MPa (8700 psia). The estimated accuracy of the correlation is ±1% in viscosity and ±2% in thermal conductivity.Units: Dual
