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

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

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

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

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:

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

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.

Member Function Documentation

◆ type()

string type ( ) const

inlineoverridevirtual

String indicating the thermodynamic model implemented.

Usually corresponds to the name of the derived class, less any suffixes such as "Phase", TP", "VPSS", etc.

Since: Starting in Cantera 3.0, the name returned by this method corresponds to the canonical name used in the YAML input format.

Reimplemented from Phase.

Definition at line 194 of file LatticePhase.h.

◆ isCompressible()

bool isCompressible ( ) const

inlineoverridevirtual

Return whether phase represents a compressible substance.

Reimplemented from Phase.

Definition at line 198 of file LatticePhase.h.

◆ nativeState()

map< string, size_t > nativeState ( ) const

inlineoverridevirtual

Return a map of properties defining the native state of a substance.

By default, entries include "T", "D", "Y" for a compressible substance and "T", "P", "Y" for an incompressible substance, with offsets 0, 1 and 2, respectively. Mass fractions "Y" are omitted for pure species. In all cases, offsets into the state vector are used by saveState() and restoreState().

Reimplemented from Phase.

Definition at line 202 of file LatticePhase.h.

◆ enthalpy_mole()

double enthalpy_mole ( ) const

overridevirtual

Return the Molar Enthalpy. Units: J/kmol.

For an ideal solution,

\[ \hat h(T,P) = \sum_k X_k \hat h^0_k(T,P), \]

The standard-state pure-species Enthalpies \( \hat h^0_k(T,P) \) are computed first by the species reference state thermodynamic property manager and then a small pressure dependent term is added in.

See also: MultiSpeciesThermo

Reimplemented from ThermoPhase.

Definition at line 26 of file LatticePhase.cpp.

◆ entropy_mole()

double entropy_mole ( ) const

overridevirtual

Molar entropy of the solution. Units: J/kmol/K.

For an ideal, constant partial molar volume solution mixture with pure species phases which exhibit zero volume expansivity:

\[ \hat s(T, P, X_k) = \sum_k X_k \hat s^0_k(T) - \hat R \sum_k X_k \ln(X_k) \]

The reference-state pure-species entropies \( \hat s^0_k(T,p_{ref}) \) are computed by the species thermodynamic property manager. The pure species entropies are independent of pressure since the volume expansivities are equal to zero.

Units: J/kmol/K.

See also: MultiSpeciesThermo

Reimplemented from ThermoPhase.

Definition at line 32 of file LatticePhase.cpp.

◆ cp_mole()

double cp_mole ( ) const

overridevirtual

Molar heat capacity at constant pressure of the solution.

Units: J/kmol/K.

For an ideal, constant partial molar volume solution mixture with pure species phases which exhibit zero volume expansivity:

\[ \hat c_p(T,P) = \sum_k X_k \hat c^0_{p,k}(T) . \]

The heat capacity is independent of pressure. The reference-state pure- species heat capacities \( \hat c^0_{p,k}(T) \) are computed by the species thermodynamic property manager.

Reimplemented from ThermoPhase.

Definition at line 37 of file LatticePhase.cpp.

double cv_mole ( ) const

overridevirtual

This method sets the pressure within the object. The mass density is not a function of pressure.

Parameters

p	Input Pressure (Pa)

Reimplemented from Phase.

Definition at line 53 of file LatticePhase.cpp.

◆ calcDensity()

double calcDensity ( )

Calculate the density of the mixture using the partial molar volumes and mole fractions as input.

The formula for this is

\[ \rho = \frac{\sum_k{X_k W_k}}{\sum_k{X_k V_k}} \]

where \( X_k \) are the mole fractions, \( W_k \) are the molecular weights, and \( V_k \) are the pure species molar volumes.

Note, the basis behind this formula is that in an ideal solution the partial molar volumes are equal to the pure species molar volumes. We have additionally specified in this class that the pure species molar volumes are independent of temperature and pressure.

Definition at line 47 of file LatticePhase.cpp.

◆ standardConcentrationUnits()

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.

This function is called after any call to setMassFractions(), setMoleFractions(), or similar.

Derived class implementations of compositionChanged() should call the parent class method as well.
