平均场状态方程结合重整化群理论的方法能预测流体的临界性质以及远离临界点的热力学性质.利用经典的参数型状态方程结合White的重整化过程计算了CO2以及多种正构烷烃(C1～C7)的汽液相平衡热力学性质,并在此基础上讨论了真实流体在临界点附近的非对称性质.计算结果表明,White的流体重整化群理论能够很好地预测流体的相平衡热力学性质,但是对于临界非对称性质不能给出与标度理论相符的结果。
The average field state equation combined with the renormalization group theory can predict the critical properties of the fluid and the thermodynamic properties far away from the critical point. Using the classical parametric state equation and White’s renormalization process, CO2 and various n-alkanes ( C1 ~ C7) vapor phase equilibrium thermodynamic properties, and on this basis, discussed the real fluid in the vicinity of the critical point of the asymmetric nature of the results show that White’s fluid renormalization group theory can predict the fluid phase Equilibrium thermodynamic properties, but for the critical asymmetric nature can not give the results in line with the scale theory.
