Detailed Description

PseudoBinaryVPSSTP is a derived class of ThermoPhase GibbsExcessVPSSTP that handles variable pressure standard state methods for calculating thermodynamic properties that are further based on expressing the Excess Gibbs free energy as a function of the mole fractions (or pseudo mole fractions) of constituents. This category is the workhorse for describing molten salts, solid-phase mixtures of semiconductors, and mixtures of miscible and semi-miscible compounds.

It includes

This class adds additional functions onto the ThermoPhase interface that handles the calculation of the excess Gibbs free energy. The ThermoPhase class includes a member function, ThermoPhase::activityConvention() that indicates which convention the activities are based on. The default is to assume activities are based on the molar convention. That default is used here.

All of the Excess Gibbs free energy formulations in this area employ symmetrical formulations.

This layer will massage the mole fraction vector to implement cation and anion based mole numbers in an optional manner

The way that it collects the cation and anion based mole numbers is via holding two extra ThermoPhase objects. These can include standard states for salts.

Constructor & Destructor Documentation

Constructor.

This doesn't do much more than initialize constants with default values for water at 25C. Water molecular weight comes from the default elements.xml file. It actually differs slightly from the IAPWS95 value of 18.015268. However, density conservation and therefore element conservation is the more important principle to follow.

ThermoPhase * duplMyselfAsThermoPhase ( ) const
virtual

Duplication routine for objects which inherit from ThermoPhase.

This virtual routine can be used to duplicate thermophase objects inherited from ThermoPhase even if the application only has a pointer to ThermoPhase to work with.

Reimplemented from GibbsExcessVPSSTP.

int eosType ( ) const
virtual

Equation of state type flag.

The ThermoPhase base class returns zero. Subclasses should define this to return a unique non-zero value. Known constants defined for this purpose are listed in mix_defs.h.

doublereal standardConcentration ( size_t  k = 0) const
virtual

The standard concentration \( C^0_k \) used to normalize the generalized concentration.

In many cases, this quantity will be the same for all species in a phase - for example, for an ideal gas \( C^0_k = P/\hat R T \). For this reason, this method returns a single value, instead of an array. However, for phases in which the standard concentration is species-specific (e.g. surface species of different sizes), this method may be called with an optional parameter indicating the species.

Parameters
kspecies index. Defaults to zero.

doublereal logStandardConc ( size_t  k = 0) const
virtual

Returns the natural logarithm of the standard concentration of the kth species.

Parameters

void getElectrochemPotentials ( doublereal *  mu) const

Get the species electrochemical potentials.

These are partial molar quantities. This method adds a term \( Fz_k \phi_k \) to the to each chemical potential.

Units: J/kmol

Parameters
muoutput vector containing the species electrochemical potentials. Length: m_kk.

void calcPseudoBinaryMoleFractions ( ) const
virtual
void initThermo ( )
virtual

Initialize. This method is provided to allow subclasses to perform any initialization required after all species have been added. For example, it might be used to resize internal work arrays that must have an entry for each species. The base class implementation does nothing, and subclasses that do not require initialization do not need to overload this method. When importing a CTML phase description, this method is called just prior to returning from function importPhase.

void initThermoXML ( XML_Node phaseNode,
const std::string &  id

virtual

Import and initialize a ThermoPhase object.

Parameters
phaseNodeThis object must be the phase node of a complete XML tree description of the phase, including all of the species data. In other words while "phase" must point to an XML phase object, it must have sibling nodes "speciesData" that describe the species in the phase.
idID of the phase. If nonnull, a check is done to see if phaseNode is pointing to the phase with the correct id.
