Helmholtz Mixture Model

 

Helmholtz Mixture Model is the term used when the thermodynamic properties of a mixture are represented by a mole-fraction weighted combination of the generalized Helmholtz free energy equations of state for the pure fluids plus a residual function, as detailed by Lemmon and Tillner-Roth.
