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.

  \f[
       u^o_k = h^o_k
  \f]

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

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

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:

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

%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:

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

Instantiation of the Class

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

XML_Node *xc = get_XML_File("diamond.xml");
XML_Node * const xs = xc->findNameID("phase", "diamond_100");
ThermoPhase *diamond100TP_tp = newPhase(*xs);
SurfPhase *diamond100TP = dynamic_cast <SurfPhase *>(diamond100TP_tp);

or by the following constructor:

XML_Node *xc = get_XML_File("diamond.xml");
XML_Node * const xs = xc->findNameID("phase", "diamond_100");
SurfPhase *diamond100TP = new SurfPhase(*xs);

XML Example

An example of an XML Element named phase setting up a SurfPhase object named diamond_100 is given below.

<phase dim="2" id="diamond_100">
   <elementArray datasrc="elements.xml">H C</elementArray>
   <speciesArray datasrc="#species_data">c6HH c6H* c6*H c6** c6HM c6HM* c6*M c6B </speciesArray>
   <reactionArray datasrc="#reaction_data"/>
   <state>
      <temperature units="K">1200.0</temperature>
      <coverages>c6H*:0.1, c6HH:0.9</coverages>
   </state>
   <thermo model="Surface">
      <site_density units="mol/cm2">3e-09</site_density>
   </thermo>
   <kinetics model="Interface"/>
   <transport model="None"/>
   <phaseArray>
        gas_phase diamond_bulk
   </phaseArray>
</phase>

The model attribute, "Surface", on the thermo element identifies the phase as being a SurfPhase object.

◆ initThermo()

Initialize.

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 a CTML phase description, this method is called from initThermoXML(), which is called from importPhase(), just prior to returning from function importPhase().

When importing from an AnyMap phase description (or from a YAML file), this method is responsible for setting model parameters from the data stored in m_input.

◆ setCoverages()

void setCoverages ( const doublereal * theta )

Set the surface site fractions to a specified state.

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

theta This is the surface site fraction for the kth species in the surface phase. This is a dimensionless quantity.

This routine normalizes the theta's to 1, before application

◆ setState()

void setState ( const AnyMap & state )

virtual

Set the state using an AnyMap containing any combination of properties supported by the thermodynamic model.

Accepted keys are:

X (mole fractions)
Y (mass fractions)
T or temperature
P or pressure [Pa]
H or enthalpy [J/kg]
U or internal-energy [J/kg]
S or entropy [J/kg/K]
V or specific-volume [m^3/kg]
D or density [kg/m^3]

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.
