lib.PTV module¶
- class lib.EoS.Cubic.PTV.PTV(T, P, mezcla, **kwargs)[source]¶
Bases:
PTPatel-Teja-Valderrama cubic equation of state implementation as explain in [1]
\[\begin{split}\begin{array}[t]{l} P = \frac{RT}{V-b}-\frac{a}{V\left(V+b\right)+c\left(V-b\right)}\\ a = \Omega_a\frac{R^2T_c^2}{P_c}\alpha\\ b = \Omega_b\frac{RT_c}{P_c}\\ c = \Omega_c\frac{RT_c}{P_c}\\ \alpha^{0.5} = 1 + F\left(1-Tr^{0.5}\right)\\ \Omega_a = 0.66121 - 0.76105 Z_c\\ \Omega_b = 0.02207 + 0.20868 Z_c\\ \Omega_c = 0.57765 - 1.87080 Z_c\\ F = 0.46283 + 3.5823\left(\omega·Z_c\right) + 8.19417\left(\omega·Z_c\right)^2\\ \end{array}\end{split}\]
