Detailed Description

This is a filter class for ThermoPhase that implements some preparatory steps for efficiently handling a variable pressure standard state for species.

Several concepts are introduced. The first concept is there are temporary variables for holding the species standard state values of Cp, H, S, G, and V at the last temperature and pressure called. These functions are not recalculated if a new call is made using the previous temperature and pressure.

To support the above functionality, pressure and temperature variables, m_Plast_ss and m_Tlast_ss, are kept which store the last pressure and temperature used in the evaluation of standard state properties.

This class is usually used for nearly incompressible phases. For those phases, it makes sense to change the equation of state independent variable from density to pressure. The variable m_Pcurrent contains the current value of the pressure within the phase.

◆ standardStateConvention()

int standardStateConvention ( ) const

virtual

This method returns the convention used in specification of the standard state, of which there are currently two, temperature based, and variable pressure based.

Currently, there are two standard state conventions:

Temperature-based activities cSS_CONVENTION_TEMPERATURE 0

◆ getdlnActCoeffdlnN_diag()

virtual void getdlnActCoeffdlnN_diag ( doublereal * dlnActCoeffdlnN_diag ) const

inlinevirtual

Get the array of log species mole number derivatives of the log activity coefficients.

Implementations should take the derivative of the logarithm of the activity coefficient with respect to the logarithm of the concentration- like variable (for example, moles) that represents the standard state. This quantity is to be used in conjunction with derivatives of that species mole number variable when the derivative of the chemical potential is taken.

units = dimensionless

Parameters

virtual

Updates the standard state thermodynamic functions at the current T and P of the solution.

If m_useTmpStandardStateStorage is true, this function must be called for every call to functions in this class. It checks to see whether the temperature or pressure has changed and thus the ss thermodynamics functions for all of the species must be recalculated.

This function is responsible for updating the following internal members, when m_useTmpStandardStateStorage is true.

m_hss_RT;
m_cpss_R;
m_gss_RT;
m_sss_R;

◆ minTemp()

double minTemp ( size_t k = npos ) const

virtual

Minimum temperature for which the thermodynamic data for the species or phase are valid.

If no argument is supplied, the value returned will be the lowest temperature at which the data for all species are valid. Otherwise, the value will be only for species k. This function is a wrapper that calls the species thermo minTemp function.

Parameters

k	index of the species. Default is -1, which will return the max of the min value over all species.

If no argument is supplied, the value returned will be the highest temperature at which the data for all species are valid. Otherwise, the value will be only for species k. This function is a wrapper that calls the species thermo maxTemp function.

Parameters

◆ 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 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.

◆ invalidateCache()

void invalidateCache ( )

protectedvirtual

Invalidate any cached values which are normally updated only when a change in state is detected.

◆ addSpecies() [2/2]

bool addSpecies ( shared_ptr< Species > spec )

virtual

Add a Species to this Phase.

Returns true if the species was successfully added, or false if the species was ignored.

Derived classes which need to size arrays according to the number of species should overload this method. The derived class implementation should call the base class method, and, if this returns true (indicating that the species has been added), adjust their array sizes accordingly.
