Mixing rules thermodynamics
WebThis mixing rule makes it possible to use a single equation of state model with equal accuracy for mixtures usually described by equations of state and for those traditionally described by activity coefficient models. It is the correct bridge between these two classes of models. Citing Literature Volume 38, Issue 5 May 1992 Pages 671-680 WebMixing Rule. The above mixing rule is quite flexible, particularly with temperature dependent interaction coefficients, and capable of describing the behaviour of …
