Detailed Description

A phase that is comprised of a fixed additive combination of other lattice phases.

This is the main way Cantera describes semiconductors and other solid phases. This ThermoPhase object calculates its properties as a sum over other LatticePhase objects. Each of the LatticePhase objects is a ThermoPhase object by itself.

The results from this LatticeSolidPhase model reduces to the LatticePhase model when there is one lattice phase and the molar densities of the sublattice and the molar density within the LatticeSolidPhase have the same values.

The mole fraction vector is redefined within the LatticeSolidPhase object. Each of the mole fractions sum to one on each of the sublattices. The routine getMoleFraction() and setMoleFraction() have been redefined to use this convention.

Specification of Species Standard State Properties

The standard state properties are calculated in the normal way for each of the sublattices. The normal way here means that a thermodynamic polynomial in temperature is developed. Also, a constant volume approximation for the pressure dependence is assumed. All of these properties are on a Joules per kmol of sublattice constituent basis.

Specification of Solution Thermodynamic Properties

The sum over the LatticePhase objects is carried out by weighting each LatticePhase object value with the molar density (kmol m-3) of its LatticePhase. Then the resulting quantity is divided by the molar density of the total compound. The LatticeSolidPhase object therefore only contains a listing of the number of LatticePhase object that comprises the solid, and it contains a value for the molar density of the entire mixture. This is the same thing as saying that

\[ L_i = L^{solid} \theta_i \]

\( L_i \) is the molar volume of the ith lattice. \( L^{solid} \) is the molar volume of the entire solid. \( \theta_i \) is a fixed weighting factor for the ith lattice representing the lattice stoichiometric coefficient. For this object the \( \theta_i \) values are fixed.

Let's take FeS2 as an example, which may be thought of as a combination of two lattices: Fe and S lattice. The Fe sublattice has a molar density of 1 gmol cm-3. The S sublattice has a molar density of 2 gmol cm-3. We then define the LatticeSolidPhase object as having a nominal composition of FeS2, and having a molar density of 1 gmol cm-3. All quantities pertaining to the FeS2 compound will be have weights associated with the sublattices. The Fe sublattice will have a weight of 1.0 associated with it. The S sublattice will have a weight of 2.0 associated with it.

Specification of Solution Density Properties

Currently, molar density is not a constant within the object, even though the species molar volumes are a constant. The basic idea is that a swelling of one of the sublattices will result in a swelling of of all of the lattices. Therefore, the molar volumes of the individual lattices are not independent of one another.

The molar volume of the Lattice solid is calculated from the following formula

\[ V = \sum_i{ \theta_i V_i^{lattice}} \]

where \( V_i^{lattice} \) is the molar volume of the ith sublattice. This is calculated from the following standard formula.

\[ V_i = \sum_k{ X_k V_k} \]

where k is a species in the ith sublattice.

The mole fraction vector is redefined within the the LatticeSolidPhase object. Each of the mole fractions sum to one on each of the sublattices. The routine getMoleFraction() and setMoleFraction() have been redefined to use this convention.

The reference-state pure-species enthalpies, \( \hat h^{ref}_k(T) \), at the reference pressure, \( P_{ref} \), are computed by the species thermodynamic property manager. They are polynomial functions of temperature.

The reference-state pure-species entropies, \( \hat s^{ref}_k(T) \), at the reference pressure, \( P_{ref} \), are computed by the species thermodynamic property manager. They are polynomial functions of temperature.

Get the array of standard state chemical potentials at unit activity for the species at their standard states at the current T and P of the solution.

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.

This returns the underlying lattice standard chemical potentials, as the units are kmol-1 of the sublattice species.

Parameters

mu0	Output vector of chemical potentials. Length: m_kk. Units: J/kmol

Reimplemented from ThermoPhase.

Definition at line 262 of file LatticeSolidPhase.cpp.

◆ standardConcentration()

double standardConcentration ( size_t k = 0 ) const

overridevirtual

Return the standard concentration for the kth species.

The standard concentration \( C^0_k \) used to normalize the activity (that is, 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 (such as surface species of different sizes), this method may be called with an optional parameter indicating the species.

Parameters

k	Optional parameter indicating the species. The default is to assume this refers to species 0.

Returns: Returns the standard concentration. The units are by definition dependent on the ThermoPhase and kinetics manager representation.

Reimplemented from ThermoPhase.

◆ addSpecies()

bool addSpecies ( shared_ptr< Species > spec )

overridevirtual

Add a Species to this Phase.

Returns true if the species was successfully added, or false if the species was ignored.

Derived classes which need to size arrays according to the number of species should overload this method. The derived class implementation should call the base class method, and, if this returns true (indicating that the species has been added), adjust their array sizes accordingly.

Reimplemented from ThermoPhase.

Definition at line 288 of file LatticeSolidPhase.cpp.

◆ initThermo()

void initThermo ( )

overridevirtual

Initialize the ThermoPhase object after all species have been set up.

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. Derived classes which do override this function should call their parent class's implementation of this function as their last action.

When importing from an AnyMap phase description (or from a YAML file), setupPhase() adds all the species, stores the input data in m_input, and then calls this method to set model parameters from the data stored in m_input.

Reimplemented from ThermoPhase.
