Detailed Description

Implementation of the polynomial extended corresponding states (pECS) mixture model
The mixture model depends on coefficients for a temperature and density polynomial.
Only valid for binary mixtures.
The pECS reducing function follow the mathematical operations:
\(F(\bar x, Y, T, \rho ) = \sum_{i=1}^{N} x_{i}^{2} Y_{\mathrm{c},i} + \sum_{i=1}^{N-1}\sum_{j=i+1}^{N} 2 x_{i} x_{j} Y_{ij} f_{Y}(T,\rho).\)
\(f_{T,v} = \sum_{i}^{n} \sum_{j}^{m-i} c_{ij,T,v} \tau_{\mathrm{ECS}}^{i} \delta_{\mathrm{ECS}}^{j}\)
\(\tau_{\mathrm{ECS}} = \frac{Y_{T,ij}}{T}\)
\(\delta_{\mathrm{ECS}} = \rho Y_{v,ij}\)
\(Y_{T,ij} = \sqrt{T_{\mathrm{c},i} T_{\mathrm{c},j}}\)
\(Y_{v,ij} = \left( \frac{1}{\rho_{\mathrm{c},i}^{1/3}} + \frac{1}{\rho_{\mathrm{c},j}^{1/3}}\right)^{3}\)
\(c_{ij,T,v} = a_{ij,1} + a_{ij,2} x_{i} + a_{ij,3} x_{i}^{2}\).
