Constructor & Destructor Documentation

◆ MaskellSolidSolnPhase()

Definition at line 20 of file MaskellSolidSolnPhase.cpp.

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 35 of file MaskellSolidSolnPhase.h.

◆ standardConcentrationUnits()

Units standardConcentrationUnits ( ) const
inlineoverridevirtual

Returns the units of the "standard concentration" for this phase.

These are the units of the values returned by the functions getActivityConcentrations() and standardConcentration(), which can vary between different ThermoPhase-derived classes, or change within a single class depending on input options. See the documentation for standardConcentration() for the derived class for specific details.

Reimplemented from ThermoPhase.

Definition at line 39 of file MaskellSolidSolnPhase.h.

◆ getActivityConcentrations()

void getActivityConcentrations ( double *  c) const
overridevirtual

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 25 of file MaskellSolidSolnPhase.cpp.

◆ standardConcentration()

double standardConcentration ( size_t  k = 0) const
inlineoverridevirtual

Return the standard concentration for the kth species.

The standard concentration \( C^0_k \) used to normalize the activity (that is, 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 (such as surface species of different sizes), this method may be called with an optional parameter indicating the species.

Parameters
kOptional 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 41 of file MaskellSolidSolnPhase.h.

◆ logStandardConc()

double logStandardConc ( size_t  k = 0) const
inlineoverridevirtual

Natural logarithm of the standard concentration of the kth species.

Parameters
kindex of the species (defaults to zero)

Reimplemented from ThermoPhase.

Definition at line 42 of file MaskellSolidSolnPhase.h.

◆ enthalpy_mole()

double enthalpy_mole ( ) const
overridevirtual

Molar enthalpy. Units: J/kmol.

Reimplemented from ThermoPhase.

Definition at line 35 of file MaskellSolidSolnPhase.cpp.

◆ entropy_mole()

double entropy_mole ( ) const
overridevirtual

Molar entropy. Units: J/kmol/K.

Reimplemented from ThermoPhase.

Definition at line 48 of file MaskellSolidSolnPhase.cpp.

◆ pressure()

double pressure ( ) const
inlineoverridevirtual

Pressure.

Units: Pa. For this incompressible system, we return the internally stored independent value of the pressure.

Reimplemented from Phase.

Definition at line 65 of file MaskellSolidSolnPhase.h.

◆ setPressure()

void setPressure ( double  p)
overridevirtual

Set the pressure at constant temperature.

Units: Pa. This method sets a constant within the object. The mass density is not a function of pressure.

Parameters
pInput Pressure (Pa)

Reimplemented from Phase.

Definition at line 72 of file MaskellSolidSolnPhase.cpp.

◆ calcDensity()

void calcDensity ( )
overridevirtual

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 pure species molar volumes. We have additionally specified in this class that the pure species molar volumes are independent of temperature and pressure.

NOTE: This function is not a member of the ThermoPhase base class.

Reimplemented from VPStandardStateTP.

Definition at line 59 of file MaskellSolidSolnPhase.cpp.

This function returns a vector of chemical potentials of the species in solution at the current temperature, pressure and mole fraction of the solution.

Parameters
muOutput vector of species chemical potentials. Length: m_kk. Units: J/kmol

Reimplemented from ThermoPhase.

Definition at line 98 of file MaskellSolidSolnPhase.cpp.

◆ getChemPotentials_RT()

void getChemPotentials_RT ( double *  mu) const
overridevirtual
Deprecated:
To be removed after Cantera 3.0. Use getChemPotentials() instead.

Reimplemented from ThermoPhase.

Definition at line 111 of file MaskellSolidSolnPhase.cpp.

◆ getStandardChemPotentials()

void getStandardChemPotentials ( double *  mu) const
overridevirtual

muOutput vector of chemical potentials. Length: m_kk.

Reimplemented from ThermoPhase.

Definition at line 150 of file MaskellSolidSolnPhase.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.

◆ getParameters()
