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