COSMOSPACE

COSMOSPACE is an activity coefficient model in which the activity coefficient of the components in a liquid chemical mixture can be related through their molar fraction.[1]

While UNIQUAC is a first order approximation, COSMOSPACE gives the exact solution of a lattice model in which pairwise molecule surfaces interact. Therefore COSMOSPACE outperforms Uniquac in the description of vapor–liquid and liquid–liquid phase equilibria.[2]
