Detailed Description

This phase object consists of a single component that can be a gas, a liquid, a mixed gas-liquid fluid, or a fluid beyond its critical point.

The object inherits from ThermoPhase. However, it's built on top of the tpx package.

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 199 of file PureFluidPhase.cpp.

doublereal standardConcentration ( size_t  k = 0) const
virtual

Return the standard concentration for the kth species.

The standard concentration \( C^0_k \) used to normalize the activity (i.e., 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.

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.

Note, for molality based formulations, this returns the molality based activities.

We resolve this function at this level by calling on the activityConcentration function. However, derived classes may want to override this default implementation.

void initThermo ( )
virtual

Initialize the ThermoPhase object after all species have been set up.

Initialize.

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. When importing a CTML phase description, this method is called from ThermoPhase::initThermoXML(), which is called from importPhase(), just prior to returning from function importPhase().
