Detailed Description

Phase information and Phase calculations for vcs.

Each phase in a vcs calculation has a vcs_VolPhase object associated with it. This object helps to coordinate property evaluations for species within the phase. Usually these evaluations must be carried out on a per phase basis. However, vcs frequently needs per species quantities. Therefore, we need an interface layer between vcs and Cantera's ThermoPhase.

The species stay in the same ordering within this structure. The vcs algorithm will change the ordering of species in the global species list. However, the indexing of species in this list stays the same. This structure contains structures that point to the species belonging to this phase in the global vcs species list.

This object is considered not to own the underlying Cantera ThermoPhase object for the phase.

This object contains an idea of the temperature and pressure. It checks to see if if the temperature and pressure has changed before calling underlying property evaluation routines.

The object contains values for the electric potential of a phase. It coordinates the evaluation of properties wrt when the electric potential of a phase has changed.

The object knows about the mole fractions of the phase. It controls the values of mole fractions, and coordinates the property evaluation wrt to changes in the mole fractions. It also will keep track of the likely values of mole fractions in multicomponent phases even when the phase doesn't actually exist within the thermo program.

The object knows about the total moles of a phase. It checks to see if the phase currently exists or not, and modifies its behavior accordingly.

Activity coefficients and volume calculations are lagged. They are only called when they are needed (and when the state has changed so that they need to be recalculated).

The index here is the local phase species index. the value of the variable is the global vcs reaction number. Note, that the global reaction number will go out of order when the species positions are swapped. So, this number has to be recalculated.
