Detailed Description

Class FixedChemPotSSTP represents a stoichiometric (fixed composition) incompressible substance.

This class internally changes the independent degree of freedom from density to pressure. This is necessary because the phase is incompressible. It uses a zero volume approximation.

Specification of Species Standard State Properties

This class inherits from SingleSpeciesTP. It uses a single value for the chemical potential which is assumed to be constant with respect to temperature and pressure.

The reference state thermodynamics is inherited from SingleSpeciesTP. However, it's only used to set the initial chemical potential to the value of the chemical potential at the starting conditions. Thereafter, it is ignored.

For a zero volume material, the internal energy and the enthalpy are equal to the chemical potential. The entropy, the heat capacity, and the molar volume are equal to zero.

Specification of Solution Thermodynamic Properties

All solution properties are obtained from the standard state species functions, since there is only one species in the phase.

Application within Kinetics Managers

The standard concentration is equal to 1.0. This means that the kinetics operator works on an (activities basis). Since this is a stoichiometric substance, this means that the concentration of this phase drops out of kinetics expressions.

An example of a reaction using this is a sticking coefficient reaction of a substance in an ideal gas phase on a surface with a bulk phase species in this phase. In this case, the rate of progress for this reaction, \( R_s \), may be expressed via the following equation:

\[ R_s = k_s C_{gas} \]

where the units for \( R_s \) are kmol m-2 s-1. \( C_{gas} \) has units of kmol m-3. Therefore, the kinetic rate constant, \( k_s \), has units of m s-1. Nowhere does the concentration of the bulk phase appear in the rate constant expression, since it's a stoichiometric phase, and the activity is always equal to 1.0.

Instantiation of the Class

This phase may be instantiated by calling the default ThermoFactory routine for Cantera. This new FixedChemPotSSTP object must then have a standalone xml file description an example of which is given below.

It may also be created by the following code snippets. The code includes the special member function setChemicalPotential( chempot), which sets the chemical potential to a specific value in J / kmol.

sprintf(file_ID,"%s#Li(Fixed)", iFile);
XML_Node *xm = get_XML_NameID("phase", file_ID, 0);
FixedChemPotSSTP *LiFixed = new FixedChemPotSSTP(*xm);
// Set the chemical potential to -2.3E7 J/kmol
LiFixed->setChemicalPotential(-2.3E7.)

or by the following call to importPhase():

sprintf(file_ID,"%s#NaCl(S)", iFile);
XML_Node *xm = get_XML_NameID("phase", file_ID, 0);
FixedChemPotSSTP solid;
importPhase(*xm, &solid);

The phase may also be created by a special constructor so that element potentials may be set. The constructor takes the name of the element and the value of the element chemical potential. An example is given below.

FixedChemPotSSTP *LiFixed = new FixedChemPotSSTP("Li", -2.3E7);

The phase model name for this is called FixedChemPot. It must be supplied as the model attribute of the thermo XML element entry.

virtual

This method returns an array of generalized concentrations.

\( C^a_k\) are defined such that \( a_k = C^a_k / C^0_k, \) where \( C^0_k \) is a standard concentration defined below and \( a_k \) are activities used in the thermodynamic functions. These activity (or generalized) concentrations are used by kinetics manager classes to compute the forward and reverse rates of elementary reactions.

These are the standard state chemical potentials \( \mu^0_k(T,P) \). The values are evaluated at the current temperature and pressure of the solution

Parameters

mu0	Output vector of chemical potentials. Length: m_kk.

void getUnitsStandardConc	(	doublereal *	uA,
		int	k = `0`,
		int	sizeUA = `6`
	)		const

virtual

Returns the units of the standard and generalized concentrations.

Note they have the same units, as their ratio is defined to be equal to the activity of the kth species in the solution, which is unitless.

This routine is used in print out applications where the units are needed. Usually, MKS units are assumed throughout the program and in the XML input files.

The base ThermoPhase class assigns the default quantities of (kmol/m3) for all species. Inherited classes are responsible for overriding the default values if necessary.

Parameters

                              dimensions in the Phase class.

uA[3] = Pa(pressure) units - default = 0;
uA[4] = Temperature units - default = 0;
uA[5] = time units - default = 0

void initThermo ( )

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. 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 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.
