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

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

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:

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

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:

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

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.
