lib.RKTwu module¶
- class lib.EoS.Cubic.RKTwu.RKTwu(T, P, mezcla, **kwargs)[source]¶
Bases:
RKEquation of state of Redlich-Kwong with a modified alpha temperature dependence by Twu, (1995) [1].
\[\begin{split}\begin{array}[t]{l} P = \frac{RT}{V-b}-\frac{a}{V\left(V+b\right)}\\ a = 0.427480263354\frac{R^2T_c^2}{P_c}\alpha\\ b = 0.086640349965\frac{RT_c}{P_c}\\ \alpha = alpha^{(0)} + \omega\left(\alpha^{(1)}-\alpha^{(0)}\right)\\ \alpha^{(0)} = T_r^{-0.201158} \exp{0.141599\left(1-T_r^{2.29528} \right)}\\ \alpha^{(1)} = T_r^{-0.660145} \exp{0.500315\left(1-T_r^{2.63165} \right)}\\ \end{array}\end{split}\]
