采用振动盘黏度计对制冷剂R143a的气相黏度进行了实验研究,温度范围为299～338 K、压力范围为0.1～2.69MPa,黏度测量的不确定度为±2.0%.利用得到的实验数据,拟合了R143a的气相黏度方程,黏度实验数据与方程的平均绝对偏差为0.20%,最大偏差为0.97%,可以满足工程应用.
The viscosity of gaseous R143a was measured with a Maxwell-type oscillating disk viscometer from 299 to 338 K at pressures of up to 2.69 MPa.The estimated uncertainty of the reported viscosity is ±2.0%.Correlation for the viscosity was presented,and the maximum absolute deviation and mean absolute deviation of the measured data from the equation were 0.97% and 0.20%,respectively.
