The SingleSpeciesTP class is a filter class for ThermoPhase. More...
#include <SingleSpeciesTP.h>
The SingleSpeciesTP class is a filter class for ThermoPhase.
What it does is to simplify the construction of ThermoPhase objects by assuming that the phase consists of one and only one type of species. In other words, it's a stoichiometric phase. However, no assumptions are made concerning the thermodynamic functions or the equation of state of the phase. Therefore it's an incomplete description of the thermodynamics. The complete description must be made in a derived class of SingleSpeciesTP.
Several different groups of thermodynamic functions are resolved at this level by this class. For example, All partial molar property routines call their single species standard state equivalents. All molar solution thermodynamic routines call the single species standard state equivalents. Activities routines are resolved at this level, as there is only one species.
It is assumed that the reference state thermodynamics may be obtained by a pointer to a populated species thermodynamic property manager class (see ThermoPhase::m_spthermo). How to relate pressure changes to the reference state thermodynamics is again left open to implementation.
Mole fraction and Mass fraction vectors are assumed to be equal to x[0] = 1 y[0] = 1, respectively. Simplifications to the interface of setState_TPY() and setState_TPX() functions result and are made within the class.
Note, this class can handle the thermodynamic description of one phase of one species. It can not handle the description of phase equilibrium between two phases of a stoichiometric compound (such as water liquid and water vapor, below the critical point). However, it may be used to describe the thermodynamics of one phase of such a compound even past the phase equilibrium point, up to the point where the phase itself ceases to be a stable phase.
This class doesn't do much at the initialization level. Its SingleSpeciesTP::initThermo() member does check that one and only one species has been defined to occupy the phase.
