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.
