| 摘 要： | 本文通过关联无量纲化剩余黏度与对比密度的关系,提出了一种推算常用制冷工质稠密流体黏度的维里型黏度状态方程.应用该方程只需已知该工质的临界参数、分子量和偏心因子即可完成计算,使得迁移性质的计算在热力学面上和平衡性质的计算保持了完整的一致性.本文通过上述方法计算了9种常用制冷工质的液相黏度,与实验数据比较显示,总平均偏差为2.36%,最大偏差为27.6%.

| Abstract: | In this study,a Virial-type viscosity Equation of State(EOS)used for predicting the vis- cosity of the viscous fluid of common refrigerant was established via relating the dimensionless residual viscosity with the reduced density.Adopting this equation,only the critical parameters,molecular weight and eccentric factor of the refrigerant are needed to conduct the calculation.Therefore,on the thermodynamic surface,there is an integrated concordance between the calculation of transport property and that of equ... |
