Detailed Description

Transport properties that act like pairwise interactions as in binary diffusion coefficients.

This class holds parameters for transport properties expressed as a matrix of pairwise interaction parameters. Input can be provided for constant or Arrhenius forms of the separate parameters.

Sample input for this method is

*    <transport model="Liquid">
*       <speciesDiffusivity>
*          <compositionDependence model="pairwiseInteraction">
*             <interaction speciesA="LiCl(L)" speciesB="KCl(L)">
*                <Dij units="m/s"> 1.0e-8 </Dij>
*                <Eij units="J/kmol"> 24.0e6 </Eij>
*             </interaction>
*          </compositionDependence>
*       </speciesDiffusivity>
*    </transport>

Member Function Documentation

◆ getMixTransProp()

doublereal getMixTransProp ( doublereal *  valueSpecies,
doublereal *  weightSpecies = 0 
)
virtual

Return the mixture transport property value.

Takes the separate species transport properties as input (this method does not know what transport property it is at this point.

Reimplemented from LiquidTranInteraction.

Definition at line 412 of file LiquidTranInteraction.cpp.

◆ getMatrixTransProp()

void getMatrixTransProp ( DenseMatrix mat,
doublereal *  speciesValues = 0 
)
virtual

Return the matrix of binary interaction parameters.

Takes the proper mixing rule for the binary interaction parameters and calculates them
