Detailed Description

Class LTPspecies_ExpT holds transport parameters for a specific liquid- phase species (LTPspecies) when the transport property is expressed as an exponential in temperature.

Used for standard state species properties with equations of the form

\[ x = f[0] \exp( f[1] T + ... + f[N] T^{N} ) \]

where f[i] are elements of the float array passed in.

As an example of the input required for LTPspecies_ExpT consider the following XML fragment

*    <species>
*      <!-- thermodynamic properties -->
*      <transport>
*        <thermalConductivity model="expT">
*           <floatArray size="2">  0.6, -15.0e-5 </floatArray>
*        </thermalConductivity>
*        <!-- other transport properties -->
*      </transport>
*    </species>
*

Constructor & Destructor Documentation

◆ LTPspecies_ExpT()

LTPspecies_ExpT	(	const XML_Node &	propNode,
		const std::string	name,
		TransportPropertyType	tp_ind,
		const thermo_t *	thermo
	)

Construct an LTPspecies object for a liquid transport property expressed as an exponential in temperature.

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

Parameters

propNode	Reference to the XML node that contains the property information. This class must 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.

Member Function Documentation

◆ duplMyselfAsLTPspecies()

LTPspecies * duplMyselfAsLTPspecies ( ) const

virtual

Duplication routine.

(virtual from LTPspecies)

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

Reimplemented from LTPspecies.

Definition at line 200 of file LTPspecies.cpp.

References LTPspecies_ExpT::LTPspecies_ExpT().

◆ getSpeciesTransProp()

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

Reimplemented from LTPspecies.
