View source for Group Contribution Methods

The {{src|models/thermodynamics.a4l}} ASCEND code provides methods for calculating vapor-liquid equilibria (VLE).

Details on various [[Group Contribution Methods]] can be found here:

The predictive Soave-Redlich-Kwong (PSRK) equation of state combines the Soave-Redlich-Kwong cubic equation of state with the Mathias-Copeman equation and the UNIFAC group-contribution method:
