Detailed Description

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

Used for standard state species properties with equations of the form

\[ x = f[0] + f[1] T + ... + f[N] T^N \]

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

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

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

Constructor & Destructor Documentation

LTPspecies_Poly ( 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 a polynomial 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
propNodeReference to the XML node that contains the property information. This class must be parameterized by reading XML_Node information.
nameString containing the species name
tp_indenum TransportPropertyType containing the property id that this object is creating a parameterization for (e.g., viscosity)
thermoconst pointer to the ThermoPhase object, which is used to find the temperature.
