| 摘 要： | 在广泛搜集标准氢（25%仲氢）黏度实验数据的基础上，运用单纯形算法拟合了标准氢的黏度计算方程，方程计算值与实验数据的偏差一般在2.0%以内。方程的适用范围为温度100～500 K，压力不超过200 MPa的区域。方程的不确定度为2.0%。方程具有一定的外推性，可以用于标准氢三相点温度到100 K以及500～1000 K，压力不超过500 MPa的区域；100 K以下，除临界区和气相区，方程的不确定度为3.0%，500 K关 键 词： | 氢 黏度 关联 |

| Abstract: | In this work,a new viscosity equation for the normal hydrogen(25% para-hydrogen) has been fitted based on an extensive selection of experimental data using simplex method.The deviations between the values calculated by the equation and the experimental data are generally less than 2.0%.The valid range of the equation is from 100 K to 500 K,with pressure up to 200 MPa.The uncertainty in viscosity of the equation is estimated to be 2.0%.In addition,the extrapolation behavior of the equation is reasonable,and ... |
