◆ phaseOfMatter()

virtual

String indicating the mechanical phase of the matter in this Phase.

Definition at line 208 of file PureFluidPhase.cpp.

◆ getActivityConcentrations()

void getActivityConcentrations ( doublereal * c ) const

This method returns an array of generalized concentrations.

\( C^a_k\) 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 (or generalized) 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, for example.

Parameters

c	Output array of generalized concentrations. The units depend upon the implementation of the reaction rate expressions within the phase.

◆ standardConcentration()

doublereal standardConcentration ( size_t k = 0 ) const

virtual

Return the standard concentration for the kth species.

The standard concentration \( C^0_k \) used to normalize the activity (i.e., generalized) concentration. In many cases, this quantity will be the same for all species in a phase - for example, for an ideal gas \( C^0_k = P/\hat R T \). For this reason, this method returns a single value, instead of an array. However, for phases in which the standard concentration is species-specific (e.g. surface species of different sizes), this method may be called with an optional parameter indicating the species.

Parameters

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

Returns: Returns the standard concentration. The units are by definition dependent on the ThermoPhase and kinetics manager representation.

Reimplemented from ThermoPhase.

Definition at line 218 of file PureFluidPhase.cpp.

virtual

Get the array of non-dimensional activities at the current solution temperature, pressure, and solution concentration.

Note, for molality based formulations, this returns the molality based activities.

We resolve this function at this level by calling on the activityConcentration function. However, derived classes may want to override this default implementation.

◆ initThermo()

void initThermo ( )

virtual

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

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.

Reimplemented from ThermoPhase.

◆ setParametersFromXML()

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.

Parameters

eosdata An XML_Node object corresponding to the "thermo" entry for this phase in the input file.

Deprecated:: The XML input format is deprecated and will be removed in Cantera 3.0.
