Detailed Description

Class SolidTransport implements transport properties for solids.

Definition at line 21 of file SolidTransport.h.

Member Function Documentation

Transport * duplMyselfAsTransport ( ) const
virtual

Duplication routine for objects which inherit from Transport.

This virtual routine can be used to duplicate objects derived from Transport even if the application only has a pointer to Transport to work with.

These routines are basically wrappers around the derived copy constructor.

Reimplemented from Transport.

Definition at line 69 of file SolidTransport.cpp.

virtual int model ( ) const
inlinevirtual

Transport model.

The transport model is the set of equations used to compute the transport properties. This method returns an integer flag that identifies the transport model implemented. The base class returns 0.

Reimplemented from Transport.

Definition at line 29 of file SolidTransport.h.

doublereal ionConductivity ( )
virtual

Returns the ionic conductivity of the phase.

The thermo phase needs to be updated (temperature) prior to calling this. The ionConductivity calculation is handled by subclasses of LTPspecies as specified in the input file.

Reimplemented from Transport.

Definition at line 132 of file SolidTransport.cpp.

References LTPspecies::getSpeciesTransProp(), and SolidTransport::m_ionConductivity.

doublereal thermalConductivity ( )
virtual

Returns the thermal conductivity of the phase.

The thermo phase needs to be updated (temperature) prior to calling this. The thermalConductivity calculation is handled by subclasses of LTPspecies as specified in the input file.

There is also a legacy method to evaluate

\[ \lambda = A T^n \exp(-E/RT) \]

Reimplemented from Transport.

Definition at line 156 of file SolidTransport.cpp.

References LTPspecies::getSpeciesTransProp(), SolidTransport::m_Alam, SolidTransport::m_Elam, SolidTransport::m_Nlam, SolidTransport::m_thermalConductivity, Transport::m_thermo, and Phase::temperature().

doublereal electricalConductivity ( )
virtual

Returns the electron conductivity of the phase.

The thermo phase needs to be updated (temperature) prior to calling this. The ionConductivity calculation is handled by subclasses of LTPspecies as specified in the input file.

There is also a legacy multicomponent diffusion approach to electrical conductivity.

Reimplemented from Transport.

doublereal defectDiffusivity ( )
virtual

The diffusivity of defects in the solid (m^2/s). The thermo phase needs to be updated (temperature) prior to calling this. The defectDiffusivity calculation is handled by subclasses of LTPspecies as specified in the input file.

Definition at line 168 of file SolidTransport.cpp.

References LTPspecies::getSpeciesTransProp(), and SolidTransport::m_defectDiffusivity.

doublereal defectActivity ( )
virtual

The activity of defects in the solid.

At some point this should be variable and the diffusion coefficient should depend on it.

The thermo phase needs to be updated (temperature) prior to calling this. The defectActivity calculation is handled by subclasses of LTPspecies as specified in the input file.

Definition at line 174 of file SolidTransport.cpp.

References LTPspecies::getSpeciesTransProp(), and SolidTransport::m_defectActivity.

void getMixDiffCoeffs ( doublereal *const  d)
virtual

Returns a vector of mixture averaged diffusion coefficients.

Mixture-averaged diffusion coefficients [m^2/s]. If the transport manager implements a mixture-averaged diffusion model, then this method returns the array of mixture-averaged diffusion coefficients. Otherwise it throws an exception.

Parameters
dReturn vector of mixture averaged diffusion coefficients Units = m2/s. Length = n_sp

Reimplemented from Transport.

Definition at line 191 of file SolidTransport.cpp.

Referenced by SolidTransport::getMobilities().

void getMobilities ( doublereal *const  mobil_e)
virtual

Get the Electrical mobilities (m^2/V/s).

This function returns the mobilities. In some formulations this is equal to the normal mobility multiplied by faraday's constant.

Frequently, but not always, the mobility is calculated from the diffusion coefficient using the Einstein relation

\[ \mu^e_k = \frac{F D_k}{R T} \]

Parameters
mobil_eReturns the mobilities of the species in array mobil_e. The array must be dimensioned at least as large as the number of species.

Reimplemented from Transport.

void setParameters ( const int  n,
const int  k,
const doublereal *const  p 
)
virtual
bool initSolid ( SolidTransportData tr)
protectedvirtual

Initialize the transport object.

Here we change all of the internal dimensions to be sufficient. We get the object ready to do property evaluations. A lot of the input required to do property evaluations is contained in the SolidTransportParams class that is filled in TransportFactory.

Parameters
trTransport parameters for all of the species in the phase.
