Detailed Description

A simple thermodynamic model for a bulk phase, assuming a lattice of solid atoms.

The bulk consists of a matrix of equivalent sites whose molar density does not vary with temperature or pressure. The thermodynamics obeys the ideal solution laws. The phase and the pure species phases which comprise the standard states of the species are assumed to have zero volume expansivity and zero isothermal compressibility.

The density of matrix sites is given by the variable \( C_o \), which has SI units of kmol m-3.

Specification of Species Standard State Properties

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). However, how to relate pressure changes to the reference state thermodynamics is within this class.

Pressure is defined as an independent variable in this phase. However, it has no effect on any quantities, as the molar concentration is a constant.

The standard state enthalpy function is given by the following relation, which has a weak dependence on the system pressure, \(P\).

\[ h^o_k(T,P) = h^{ref}_k(T) + \left( \frac{P - P_{ref}}{C_o} \right) \]

For an incompressible substance, the molar internal energy is independent of pressure. Since the thermodynamic properties are specified by giving the standard-state enthalpy, the term \( \frac{P_{ref}}{C_o} \) is subtracted from the specified reference molar enthalpy to compute the standard state molar internal energy:

\[ u^o_k(T,P) = h^{ref}_k(T) - \frac{P_{ref}}{C_o} \]

The standard state heat capacity, internal energy, and entropy are independent of pressure. The standard state Gibbs free energy is obtained from the enthalpy and entropy functions.

The standard state molar volume is independent of temperature, pressure, and species identity:

\[ V^o_k(T,P) = \frac{1.0}{C_o} \]


Specification of Solution Thermodynamic Properties


The activity of species \( k \) defined in the phase, \( a_k \), is given by the ideal solution law:

\[ a_k = X_k , \]

where \( X_k \) is the mole fraction of species k. The chemical potential for species k is equal to

\[ \mu_k(T,P) = \mu^o_k(T, P) + R T \log(X_k) \]

The partial molar entropy for species k is given by the following relation,

\[ \tilde{s}_k(T,P) = s^o_k(T,P) - R \log(X_k) = s^{ref}_k(T) - R \log(X_k) \]

The partial molar enthalpy for species k is

\[ \tilde{h}_k(T,P) = h^o_k(T,P) = h^{ref}_k(T) + \left( \frac{P - P_{ref}}{C_o} \right) \]

The partial molar Internal Energy for species k is

\[ \tilde{u}_k(T,P) = u^o_k(T,P) = u^{ref}_k(T) \]

The partial molar Heat Capacity for species k is

\[ \tilde{Cp}_k(T,P) = Cp^o_k(T,P) = Cp^{ref}_k(T) \]

The partial molar volume is independent of temperature, pressure, and species identity:

\[ \tilde{V}_k(T,P) = V^o_k(T,P) = \frac{1.0}{C_o} \]

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 resolved at this level.

Pressure is defined as an independent variable in this phase. However, it only has a weak dependence on the enthalpy, and doesn't effect the molar concentration.


Application within Kinetics Managers


\( C^a_k\) are defined such that \( C^a_k = a_k = X_k \) \( C^s_k \), the standard concentration, is defined to be equal to one. \( a_k \) 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. The activity concentration, \( C^a_k \), is given by the following expression.

\[ C^a_k = C^s_k X_k = X_k \]

The standard concentration for species k is identically one

\[ C^s_k = C^s = 1.0 \]

For example, a bulk-phase binary gas reaction between species j and k, producing a new species l would have the following equation for its rate of progress variable, \( R^1 \), which has units of kmol m-3 s-1.

\[ R^1 = k^1 C_j^a C_k^a = k^1 X_j X_k \]

The reverse rate constant can then be obtained from the law of microscopic reversibility and the equilibrium expression for the system.

\[ \frac{X_j X_k}{ X_l} = K_a^{o,1} = \exp(\frac{\mu^o_l - \mu^o_j - \mu^o_k}{R T} ) \]

\( K_a^{o,1} \) is the dimensionless form of the equilibrium constant, associated with the pressure dependent standard states \( \mu^o_l(T,P) \) and their associated activities, \( a_l \), repeated here:

\[ \mu_l(T,P) = \mu^o_l(T, P) + R T \log(a_l) \]

The concentration equilibrium constant, \( K_c \), may be obtained by changing over to activity concentrations. When this is done:

\[ \frac{C^a_j C^a_k}{ C^a_l} = C^o K_a^{o,1} = K_c^1 = \exp(\frac{\mu^{o}_l - \mu^{o}_j - \mu^{o}_k}{R T} ) \]

Kinetics managers will calculate the concentration equilibrium constant, \( K_c \), using the second and third part of the above expression as a definition for the concentration equilibrium constant.


Instantiation of the Class


The constructor for this phase is located in the default ThermoFactory for Cantera. A new LatticePhase object may be created by the following code snippet:

XML_Node *xc = get_XML_File("O_lattice_SiO2.xml");
XML_Node * const xs = xc->findNameID("phase", "O_lattice_SiO2");
ThermoPhase *tp = newPhase(*xs);
LatticePhase *o_lattice = dynamic_cast <LatticPhase *>(tp);

or by the following constructor:

XML_Node *xc = get_XML_File("O_lattice_SiO2.xml");
XML_Node * const xs = xc->findNameID("phase", "O_lattice_SiO2");
LatticePhase *o_lattice = new LatticePhase(*xs);

The XML file used in this example is listed in the next section

void getCp_R ( doublereal *  cpr) const
virtual

Get the nondimensional Heat Capacities at constant pressure for the species standard states at the current T and P of the solution.

The heat capacity of the standard state is independent of pressure

\[ Cp^o_k(T,P) = Cp^{ref}_k(T) \]

The reference state thermodynamics is 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 resolved at this level.

Parameters
cprOutput vector of nondimensional standard state heat capacities Length: m_kk.

void initThermo ( )
virtual

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

Initialize.

This method performs any initialization required after all species have been added. For example, it is used to resize internal work arrays that must have an entry for each species. This method is called from ThermoPhase::initThermoXML(), which is called from importPhase(), just prior to returning from the 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.

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.

void setParametersFromXML ( const XML_Node eosdata)
virtual

Set equation of state parameter values from XML entries.

This method is called by function importPhase() when processing a phase definition in an input file. It should be overloaded in subclasses to set any parameters that are specific to that particular phase model. Note, this method is called before the phase is initialized with elements and/or species.

For this phase, the molar density of the phase is specified in this block, and is a required parameter.

Parameters
eosdataAn XML_Node object corresponding to the "thermo" entry for this phase in the input file.

eosdata points to the thermo block, and looks like this:

<phase id="O_lattice_SiO2" >
<thermo model="Lattice">
<site_density units="kmol/m^3"> 73.159 </site_density>
<vacancy_species> "O_vacancy" </vacancy_species>
</thermo>
</phase>

The current pressure.

Since the density isn't a function of pressure, but only of the mole fractions, we need to independently specify the pressure. The density variable which is inherited as part of the State class, m_dens, is always kept current whenever T, P, or X[] change.
