Detailed Description

Class LTPspecies holds transport parameterizations for a specific liquid-phase species.

Subclasses handle different means of specifying transport properties like constant, Arrhenius or polynomial temperature fits. In its current state, it is primarily suitable for specifying temperature dependence, but the adjustCoeffsForComposition() method can be implemented to adjust for the composition dependence.

Mixing rules for computing mixture transport properties are handled separately in the LiquidTranInteraction subclasses.

Constructor & Destructor Documentation

LTPspecies	(	const XML_Node *const	propNode = `0`,
		const std::string	name = `"-"`,
		TransportPropertyType	tp_ind = `TP_UNKNOWN`,
		const thermo_t *	thermo = `0`
	)

Construct an LTPspecies object for a liquid transport property.

The species transport property is constructed from the XML node, <propNode> that is a child of the <transport> node in the species block and specifies a type of transport property (like viscosity)

Parameters

propNode	Pointer to the XML node that contains the property information. A default value of 0 is allowed for the base class, but not for classes which are assumed to be parameterized by reading XML_Node information.
name	String containing the species name
tp_ind	enum TransportPropertyType containing the property id that this object is creating a parameterization for (e.g., viscosity)
thermo	const pointer to the ThermoPhase object, which is used to find the temperature.

LTPspecies * duplMyselfAsLTPspecies ( ) const

virtual

Duplication routine.

(virtual from LTPspecies)

Returns: Returns a copy of this routine as a pointer to LTPspecies

Reimplemented in LTPspecies_ExpT, LTPspecies_Poly, LTPspecies_Arrhenius, and LTPspecies_Const.

doublereal getSpeciesTransProp ( )

virtual

Returns the vector of standard state species transport property.

The standard state species transport property is returned. Any temperature and composition dependence will be adjusted internally according to the information provided by the subclass object.

Returns: Returns a single double containing the property evaluation at the current ThermoPhase temperature.

bool checkPositive ( ) const

virtual

Check to see if the property evaluation will be positive.

doublereal getMixWeight ( ) const

Return the weight mixture.

void adjustCoeffsForComposition ( )

privatevirtual

Internal model to adjust species-specific properties for the composition.

Currently just a place holder, but this method could take the composition from the thermo object and adjust coefficients according to some yet unspecified model.

doublereal m_mixWeight

protected

Weighting used for mixing.

This weighting can be employed to allow salt transport properties to be represented by specific ions. For example, to have Li+ and Ca+ represent the mixing transport properties of LiCl and CaCl2, the weightings for Li+ would be 2.0, for K+ would be 3.0 and for Cl- would be 0.0. The transport properties for Li+ would be those for LiCl and the transport properties for Ca+ would be those for CaCl2. The transport properties for Cl- should be something innoccuous like 1.0–note that 0.0 is not innocuous if there are logarithms involved.
