Detailed Description

MolarityIonicVPSSTP is a derived class of 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 the constituents. This category is the workhorse for describing ionic systems which are not on the molality scale.

Attention: This class currently does not have any test cases or examples. Its implementation may be incomplete, and future changes to Cantera may unexpectedly cause this class to stop working. If you use this class, please consider contributing examples or test cases. In the absence of new tests or examples, this class may be deprecated and removed in a future version of Cantera. See https://github.com/Cantera/cantera/issues/267 for additional information.

Deprecated:: To be removed after Cantera 2.4

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, such that it is expected that there exists a charge balance at all times. One of the ions must be a "special ion" in the sense that its' thermodynamic functions are set to zero, and the thermo functions of all other ions are based on a valuation relative to that special ion.

◆ initThermoXML()

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

virtual

Import and initialize a ThermoPhase object using an XML tree.

Here we read extra information about the XML description of a phase. Regular information about elements and species and their reference state thermodynamic information have already been read at this point. For example, we do not need to call this function for ideal gas equations of state. This function is called from importPhase() after the elements and the species are initialized with default ideal solution level data.

The default implementation in ThermoPhase calls the virtual function initThermo() and then sets the "state" of the phase by looking for an XML element named "state", and then interpreting its contents by calling the virtual function setStateFromXML().

Parameters

phaseNode	This 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.
id	ID of the phase. If nonnull, a check is done to see if phaseNode is pointing to the phase with the correct id.

		doublereal	threshold = `1e-14`

returns a summary of the state of the phase as a string

◆ s_update_dlnActCoeff_dX_()

void s_update_dlnActCoeff_dX_ ( ) const

private

Internal routine that calculates the derivative of the activity coefficients wrt the mole fractions.

This routine calculates the the derivative of the activity coefficients wrt to mole fraction with all other mole fractions held constant. This is strictly not permitted. However, if the resulting matrix is multiplied by a permissible deltaX vector then everything is ok.

This is the natural way to handle concentration derivatives in this routine.
