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

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.

Constructor & Destructor Documentation

This doesn't do much more than initialize constants with default values for water at 25C. Water molecular weight comes from the default elements.xml file. It actually differs slightly from the IAPWS95 value of 18.015268. However, density conservation and therefore element conservation is the more important principle to follow.

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.

Reimplemented from VPStandardStateTP.

Reimplemented in PhaseCombo_Interaction, MargulesVPSSTP, MixedSolventElectrolyte, RedlichKisterVPSSTP, IonsFromNeutralVPSSTP, MolarityIonicVPSSTP, and PseudoBinaryVPSSTP.

Definition at line 51 of file GibbsExcessVPSSTP.cpp.

void setPressure ( doublereal  p)
virtual

Set the internally stored pressure (Pa) at constant temperature and composition.

This method sets the pressure within the object. The water model is a completely compressible model. Also, the dielectric constant is pressure dependent.

Parameters
pinput Pressure (Pa)
Todo:
Implement a variable pressure capability

Reimplemented from VPStandardStateTP.

Reimplemented in IonsFromNeutralVPSSTP.

Definition at line 89 of file GibbsExcessVPSSTP.cpp.

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 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.

Definition at line 94 of file GibbsExcessVPSSTP.cpp.

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 127 of file GibbsExcessVPSSTP.cpp.

doublereal standardConcentration ( size_t  k = 0) const
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
kspecies index. Defaults to zero.

Reimplemented from ThermoPhase.

Reimplemented in PseudoBinaryVPSSTP.

Definition at line 132 of file GibbsExcessVPSSTP.cpp.

doublereal logStandardConc ( size_t  k = 0) const
virtual

Returns the natural logarithm of the standard concentration of the kth species.

Parameters
kspecies index

Reimplemented from ThermoPhase.

Definition at line 137 of file GibbsExcessVPSSTP.cpp.

void getUnitsStandardConc ( double *  uA,
int  k = 0,
int  sizeUA = 6 
) const
virtual

Returns the units of the standard and generalized concentrations Note they have the same units, as their ratio is defined to be equal to the activity of the kth species in the solution, which is unitless.

This routine is used in print out applications where the units are needed. Usually, MKS units are assumed throughout the program and in the XML input files.

Parameters
uAOutput vector containing the units uA[0] = kmol units - default = 1 uA[1] = m units - default = -nDim(), the number of spatial dimensions in the Phase class. uA[2] = kg units - default = 0; uA[3] = Pa(pressure) units - default = 0; uA[4] = Temperature units - default = 0; uA[5] = time units - default = 0
kspecies index. Defaults to 0.
sizeUAoutput int containing the size of the vector. Currently, this is equal to 6.
