24 Class
25  Foam::NonRandomTwoLiquid
26 
27 Description
28  Non ideal law for the mixing of two species. A separate composition model
29  is given for each species. The composition of a species is equal to the
30  value given by the model, scaled by the species fraction in the bulk of the
31  other phase, and multiplied by the activity coefficient for that species.
32  The gas behaviour is assumed ideal; i.e. the fugacity coefficient is taken
33  as equal to 1.
