Detailed Description

A simple thermodynamic model for a surface phase, assuming an ideal solution model.

The surface consists of a grid of equivalent sites. Surface species may be defined to occupy one or more sites. The surface species are assumed to be independent, and thus the species form an ideal solution.

The density of surface sites is given by the variable \( n_0 \), which has SI units of kmol m-2.

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). 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 has no effect on any quantities, as the molar concentration is a constant.

Therefore, The standard state internal energy for species k is equal to the enthalpy for species k.

\[ u^o_k = h^o_k \]

Also, the standard state chemical potentials, entropy, and heat capacities are independent of pressure. The standard state Gibbs free energy is obtained from the enthalpy and entropy functions.

Specification of Solution Thermodynamic Properties

The activity of species defined in the phase is given by

\[ a_k = \theta_k \]

The chemical potential for species k is equal to

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

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 internal energy for species k is equal to the enthalpy for species k

\[ u_k = h_k \]

The entropy for the phase is given by the following relation, which is independent of the pressure:

\[ s_k(T,P) = s^o_k(T) - R \ln \theta_k \]

Application within Kinetics Managers

The activity concentration, \( C^a_k \), used by the kinetics manager, is equal to the actual concentration, \( C^s_k \), and is given by the following expression.

\[ C^a_k = C^s_k = \frac{\theta_k n_0}{s_k} \]

The standard concentration for species k is:

\[ C^0_k = \frac{n_0}{s_k} \]

An example phase definition is given in the YAML API Reference.

		const string &	id = `""`
	)

explicit

Construct and initialize a SurfPhase ThermoPhase object directly from an input file.

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 109 of file SurfPhase.h.

◆ isCompressible()

bool isCompressible ( ) const

inlineoverridevirtual

Return whether phase represents a compressible substance.

Reimplemented from Phase.

Definition at line 113 of file SurfPhase.h.

◆ enthalpy_mole()

double enthalpy_mole ( ) const

overridevirtual

Return the Molar Enthalpy. Units: J/kmol.

For an ideal solution,

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

and is a function only of temperature. The standard-state pure-species Enthalpies \( \hat h^0_k(T) \) are computed by the species thermodynamic property manager.

See also: MultiSpeciesThermo

Reimplemented from ThermoPhase.

Definition at line 28 of file SurfPhase.cpp.

◆ intEnergy_mole()

double intEnergy_mole ( ) const

overridevirtual

Return the Molar Internal Energy. Units: J/kmol.

For a surface phase, the pressure is not a relevant thermodynamic variable, and so the Enthalpy is equal to the Internal Energy.

◆ entropy_mole()

double entropy_mole ( ) const

overridevirtual

Return the Molar Entropy. Units: J/kmol-K.

Parameters

mu	Output vector of chemical potentials. Length: m_kk.

Reimplemented from ThermoPhase.

Definition at line 97 of file SurfPhase.cpp.

◆ getActivityConcentrations()

void getActivityConcentrations ( double * c ) const

overridevirtual

Return a vector of activity concentrations for each species.

For this phase the activity concentrations, \( C^a_k \), are defined to be equal to the actual concentrations, \( C^s_k \). Activity concentrations are

\[ C^a_k = C^s_k = \frac{\theta_k n_0}{s_k} \]

where \( \theta_k \) is the surface site fraction for species k, \( n_0 \) is the surface site density for the phase, and \( s_k \) is the surface size of species k.

\( C^a_k \) that 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 concentrations are used by kinetics manager classes to compute the forward and reverse rates of elementary reactions. Note that they may or may not have units of concentration — they might be partial pressures, mole fractions, or surface coverages,

Parameters

c	vector of activity concentration (kmol m-2).

Reimplemented from ThermoPhase.

Definition at line 113 of file SurfPhase.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. For this phase, the standard concentration is species- specific

\[ C^0_k = \frac{n_0}{s_k} \]

This definition implies that the activity is equal to \( \theta_k \).

Parameters

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

Returns: the standard concentration in units of kmol/m^2 for surface phases or kmol/m for edge phases.

Reimplemented from ThermoPhase.

Definition at line 118 of file SurfPhase.cpp.

◆ logStandardConc()

double logStandardConc ( size_t k = 0 ) const

overridevirtual

Reimplemented from ThermoPhase.

Definition at line 123 of file SurfPhase.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.

Definition at line 319 of file SurfPhase.cpp.

◆ getParameters()

void getParameters ( AnyMap & phaseNode ) const

overridevirtual

Store the parameters of a ThermoPhase object such that an identical one could be reconstructed using the newThermo(AnyMap&) function.

This does not include user-defined fields available in input().

Reimplemented from ThermoPhase.

Definition at line 328 of file SurfPhase.cpp.

◆ 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 Phase.

Definition at line 185 of file SurfPhase.cpp.

This routine converts to concentrations in kmol/m2, using m_n0, the surface site density, and size(k), which is defined to be the number of surface sites occupied by the kth molecule. It then calls Phase::setConcentrations to set the internal concentration in the object.

Parameters

U or internal-energy [J/kg]
S or entropy [J/kg/K]
V or specific-volume [m^3/kg]

Composition can be specified as either an AnyMap of species names to values or as a composition string. All other values can be given as floating point values in Cantera's default units, or as strings with the units specified, which will be converted using the Units class.

If no thermodynamic property pair is given, or only one of temperature or pressure is given, then 298.15 K and 101325 Pa will be used as necessary to fully set the state.

Additionally uses the key coverages to set the fractional coverages.
