Member Function Documentation

◆ duplMyselfAsThermoPhase()

ThermoPhase * duplMyselfAsThermoPhase ( ) const
virtual

Duplication routine for objects which inherit from ThermoPhase.

This virtual routine can be used to duplicate ThermoPhase objects inherited from ThermoPhase even if the application only has a pointer to ThermoPhase to work with.

These routines are basically wrappers around the derived copy constructor.

Deprecated:
To be removed after Cantera 2.3 for all classes derived from ThermoPhase.

Reimplemented from VPStandardStateTP.

Definition at line 67 of file IdealSolnGasVPSS.cpp.

◆ eosType()

int eosType ( ) const
virtual

Equation of state type flag.

The base class returns zero. Subclasses should define this to return a unique non-zero value. Constants defined for this purpose are listed in mix_defs.h.

Deprecated:
To be removed after Cantera 2.3. Use type() instead.

doublereal isothermalCompressibility ( ) const
virtual

Returns the isothermal compressibility. Units: 1/Pa.

The isothermal compressibility is defined as

or

\[ \kappa_T = \frac{1}{\rho}\left(\frac{\partial \rho}{\partial P}\right)_T \]

◆ calcDensity()

void calcDensity ( )
protectedvirtual

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 species standard state molar volumes. The species molar volumes may be functions of temperature and pressure.

◆ getActivityConcentrations()

void getActivityConcentrations ( doublereal *  c) const
virtual

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

Reimplemented from ThermoPhase.

Definition at line 141 of file IdealSolnGasVPSS.cpp.

◆ standardConcentration()

doublereal standardConcentration ( size_t  k = 0) const
virtual

Returns the standard concentration \( C^0_k \), which is used to normalize the generalized concentration.

This is defined as the concentration by which the generalized concentration is normalized to produce the activity. In many cases, this quantity will be the same for all species in a phase. Since the activity for an ideal gas mixture is simply the mole fraction, for an ideal gas \( C^0_k = P/\hat R T \).

Parameters
kOptional parameter indicating the species. The default is to assume this refers to species 0.
Returns
Returns the standard Concentration in units of m3 kmol-1.

◆ 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
eosdataAn XML_Node object corresponding to the "thermo" entry for this phase in the input file.

◆ initThermoXML()

void initThermoXML ( XML_Node phaseNode,
const std::string &  id 
)
virtual

Import and initialize a ThermoPhase object using an XML tree.

Here we read extra information about the XML description of a phase. Regular information about elements and species and their reference state thermodynamic information have already been read at this point. For example, we do not need to call this function for ideal gas equations of state. This function is called from importPhase() after the elements and the species are initialized with default ideal solution level data.

The default implementation in ThermoPhase calls the virtual function initThermo() and then sets the "state" of the phase by looking for an XML element named "state", and then interpreting its contents by calling the virtual function setStateFromXML().

Parameters
phaseNodeThis object must be the phase node of a complete XML tree description of the phase, including all of the species data. In other words while "phase" must point to an XML phase object, it must have sibling nodes "speciesData" that describe the species in the phase.
idID of the phase. If nonnull, a check is done to see if phaseNode is pointing to the phase with the correct id.
