lib.PTVC module¶
- class lib.EoS.Cubic.PTVC.PTVC(T, P, mezcla, **kwargs)[source]¶
Bases:
PTPatel-Teja-Valderrama-Cisternas cubic equation of state implementation as explain in [1]
\[\begin{split}\begin{array}[t]{l} P = \frac{RT}{V-b}-\frac{a}{V\left(V+b\right)+c\left(V-b\right)}\\ a = \Omega_a\frac{R^2T_c^2}{P_c}\alpha\\ b = \Omega_b\frac{RT_c}{P_c}\\ c = \Omega_c\frac{RT_c}{P_c}\\ \alpha^{0.5} = 1 + F\left(1-Tr^{0.5}\right)\\ F = -6.608 + 70.43Z_c - 159.0Z_c^2\\ \Omega_a = 0.69368018 - 1.0634424 Z_c + 0.68289995 Z_c^2 - 0.21044403 Z_c^3 + 0.003752658 Z_c^4\\ \Omega_b = 0.025987178 + 0.180754784 Z_c + 0.061258949 Z_c^2\\ \Omega_c = 0.577500514 - 1.898414283 Z_c\\ \end{array}\end{split}\]
