| 摘 要： | 为了考察不同状态方程对摩擦理论黏度模型拟合结果的影响,以制冷剂R134a为例,分别采用工程上常用的PR(Peng-Robinson)方程、MBWR(modified benediet-webbrubin)方程和R134a的专用状态方程Span-Wagner方程建立了R134a的摩擦理论黏度模型.计算结果表明,用这三个方...

| Abstract: | In order to compare the influence of different equation of states on the friction theory viscosity model of refrigerant R134a,three different equation of states,such as PR EOS,MBWR EOS and Span-Wagner EOS,were used to establish the viscosity model of R134a based on the friction theory,which called f-PR model,f-MBWR model,and f-SW model,respectively.The results showed that,the accuracy of the three types of friction theory viscosity model for R134a was almost the same in the liquid region.But in the gaseous ... |
