Detailed Description
GibbsExcessVPSSTP is a derived class of ThermoPhase that handles variable pressure standard state methods for calculating thermodynamic properties that are further based on expressing the Excess Gibbs free energy as a function of the mole fractions (or pseudo mole fractions) of constituents. This category is the workhorse for describing molten salts, solid-phase mixtures of semiconductors, and mixtures of miscible and semi-miscible compounds.
It includes
- regular solutions
- Margules expansions
- NTRL equation
- Wilson's equation
- UNIQUAC equation of state.
This class adds additional functions onto the ThermoPhase interface that handles the calculation of the excess Gibbs free energy. The ThermoPhase class includes a member function, ThermoPhase::activityConvention() that indicates which convention the activities are based on. The default is to assume activities are based on the molar convention. That default is used here.
All of the Excess Gibbs free energy formulations in this area employ symmetrical formulations.
Chemical potentials of species k, \( \mu_o \), has the following general format:
\[ \mu_k = \mu^o_k(T,P) + R T ln( \gamma_k X_k ) \]
where \( \gamma_k^{\triangle} \) is a molar based activity coefficient for species \(k\).
GibbsExcessVPSSTP contains an internal vector with the current mole fraction vector. That's one of its primary usages. In order to keep the mole fraction vector constant, all of the setState functions are redesigned at this layer.
Activity Concentrations: Relationship of ThermoPhase to %Kinetics Expressions
As explained in a similar discussion in the ThermoPhase class, the actual units used in kinetics expressions must be specified in the ThermoPhase class for the corresponding species. These units vary with the field of study. Cantera uses the concept of activity concentrations to represent this. Activity concentrations are used directly in the expressions for kinetics. Standard concentrations are used as the multiplicative constant that takes the activity of a species and turns it into an activity concentration. Standard concentrations must not depend on the concentration of the species in the phase.
Here we set a standard for the specification of the standard concentrations for this class and all child classes underneath it. We specify here that the standard concentration is equal to 1 for all species. Therefore, the activities appear directly in kinetics expressions involving species in underlying GibbsExcessVPSSTP phases.
SetState Strategy
All setState functions that set the internal state of the ThermoPhase object are overloaded at this level, so that a current mole fraction vector is maintained within the object.

Member Function Documentation
◆ 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 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 is a non-virtual function, which is not a member of the ThermoPhase base class.
Reimplemented from VPStandardStateTP.
Reimplemented in IonsFromNeutralVPSSTP.
Definition at line 32 of file GibbsExcessVPSSTP.cpp.
◆ standardConcentrationUnits()
|
virtual |
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 45 of file GibbsExcessVPSSTP.cpp.
◆ getActivityConcentrations()
|
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
-
c Output array of generalized concentrations. The units depend upon the implementation of the reaction rate expressions within the phase.
Reimplemented from ThermoPhase.
Definition at line 50 of file GibbsExcessVPSSTP.cpp.
◆ standardConcentration()
|
virtual |
The standard concentration \( C^0_k \) used to normalize the 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.
The standard concentration for defaulted to 1. In other words the activity concentration is assumed to be 1.
- Parameters
-
k species index. Defaults to zero.
Reimplemented from ThermoPhase.
Definition at line 55 of file GibbsExcessVPSSTP.cpp.
◆ logStandardConc()
|
virtual |
Natural logarithm of the standard concentration of the kth species.
- Parameters
-
k index of the species (defaults to zero)
Reimplemented from ThermoPhase.
Definition at line 60 of file GibbsExcessVPSSTP.cpp.
◆ getActivities()
|
virtual |
Get the array of non-dimensional activities (molality based for this class and classes that derive from it) at the current solution temperature, pressure, and solution concentration.
\[ a_i^\triangle = \gamma_k^{\triangle} \frac{m_k}{m^\triangle} \]
This function must be implemented in derived classes.
- Parameters
-
ac Output vector of molality-based activities. Length: m_kk.
Reimplemented from ThermoPhase.
Definition at line 65 of file GibbsExcessVPSSTP.cpp.
◆ getActivityCoefficients()
|
virtual |
Get the array of non-dimensional molar-based activity coefficients at the current solution temperature, pressure, and solution concentration.
- Parameters
-
ac Output vector of activity coefficients. Length: m_kk.
Reimplemented from ThermoPhase.
Reimplemented in IonsFromNeutralVPSSTP.
Definition at line 74 of file GibbsExcessVPSSTP.cpp.
◆ getdlnActCoeffdT()
|
inlinevirtual |
Get the array of temperature derivatives of the log activity coefficients.
This function is virtual, and first appears in GibbsExcessVPSSTP.
units = 1/Kelvin
- Parameters
-
dlnActCoeffdT Output vector of temperature derivatives of the log Activity Coefficients. length = m_kk
Reimplemented in RedlichKisterVPSSTP, and MargulesVPSSTP.
Definition at line 180 of file GibbsExcessVPSSTP.h.
Referenced by IonsFromNeutralVPSSTP::s_update_dlnActCoeffdT().
◆ getdlnActCoeffdlnN()
|
inlinevirtual |
Get the array of derivatives of the log activity coefficients with respect to the log of the species mole numbers.
Implementations should take the derivative of the logarithm of the activity coefficient with respect to a species log mole number (with all other species mole numbers held constant). The default treatment in the ThermoPhase object is to set this vector to zero.
units = 1 / kmol
dlnActCoeffdlnN[ ld * k + m] will contain the derivative of log act_coeff for the m-th species with respect to the number of moles of the k-th species.
\[ \frac{d \ln(\gamma_m) }{d \ln( n_k ) }\Bigg|_{n_i} \]
- Parameters
-
ld Number of rows in the matrix dlnActCoeffdlnN Output vector of derivatives of the log Activity Coefficients. length = m_kk * m_kk
Reimplemented from ThermoPhase.

◆ getdlnActCoeffdlnX()
|
inlinevirtual |
Get the array of log concentration-like derivatives of the log activity coefficients.
This function is a virtual method. For ideal mixtures (unity activity coefficients), this can return zero. Implementations should take the derivative of the logarithm of the activity coefficient with respect to the logarithm of the concentration-like variable (i.e. number of moles in in a unit volume. ) that represents the standard state. This quantity is to be used in conjunction with derivatives of that concentration-like variable when the derivative of the chemical potential is taken.
units = dimensionless
- Parameters
-
dlnActCoeffdlnX Output vector of derivatives of the log Activity Coefficients. length = m_kk
Definition at line 205 of file GibbsExcessVPSSTP.h.
◆ getPartialMolarVolumes()
|
virtual |
Return an array of partial molar volumes for the species in the mixture.
Units: m^3/kmol.
Frequently, for this class of thermodynamics representations, the excess Volume due to mixing is zero. Here, we set it as a default. It may be overridden in derived classes.
- Parameters
-
vbar Output vector of species partial molar volumes. Length = m_kk. units are m^3/kmol.
Reimplemented from ThermoPhase.

Reimplemented from VPStandardStateTP.

Definition at line 111 of file GibbsExcessVPSSTP.cpp.
◆ compositionChanged()
|
protectedvirtual |
Apply changes to the state which are needed after the composition changes.
This function is called after any call to setMassFractions(), setMoleFractions(), or similar. For phases which need to execute a callback after any change to the composition, it should be done by overriding this function rather than overriding all of the composition- setting functions. Derived class implementations of compositionChanged() should call the parent class method as well.
