Detailed Description

Simple mass fraction weighting of transport properties.

This model weights the transport property by the mass fractions. The overall formula for the mixture viscosity is

\[ \eta_{mix} = \sum_i Y_i \eta_i + \sum_i \sum_j Y_i Y_j A_{i,j} \]

◆ 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.

◆ getMatrixTransProp()

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

Return the matrix of binary interaction parameters.

Takes the proper mixing rule for the binary interaction parameters and calculates them: Not implemented for this mixing rule.
