lib.SRKAPI module¶
- class lib.EoS.Cubic.SRKAPI.SRKAPI(T, P, mezcla, **kwargs)[source]¶
Bases:
SRKCubic equation of state derived from Soave-Redlich-Kwong and described in [1], Procedure 8D1.1.
\[\begin{split}\begin{array}[t]{l} P = \frac{RT}{V-b}-\frac{a}{V\left(V+b\right)}\\ a = 0.42747\frac{R^2T_c^2}{P_c}\alpha\\ b = 0.08664\frac{RT_c}{P_c}\\ \alpha^{0.5} = 1 + S_1\left(1-\sqrt{Tr}\right) + S_2\frac{\left(1-\sqrt{Tr}\right)}{\sqrt{T_r}}\\ S_1 = 0.48508 + 1.55171\omega - 0.15613\omega^2\\ \end{array}\end{split}\]\(S_1\) generalized correlation is given in [2]
This method define too its custom mixture interaction parameters from [3] and [4]
