Abstract:
The accurate reduced potential energies for two binary gas mixtures including benzene-methanol and methane-tetrafluoromethane at low density have been obtained by direct inversion of the viscosity collision integral equations. The kinetic theory along with the extended principle of corresponding-states has been used to calculate the viscosity and dif-fusion coefficients over a wide range of temperature and composition. Good agreements between calculated and experimental data are obtained.

半经验反演方法计算两个二元气体混合物的粘度和扩散系数
H. R. Rafiee*,M. Rastgar,N. Heidari
摘要:
利用粘度碰撞积分方程的直接反演方法计算了两个二元气体混合体系即苯-甲醇和甲烷-四氟甲烷的低密度势能.另外利用动力学理论以及对应态原理计算了两种体系不同温度和不同比例的粘度系数和扩散系数.计算结果和实验数据具有较好的一致性.
