Detailed Description

Transport package using polynomial functions of ln(T) for mu and kappa:

\[ ln(mu) = \sum_{i=1}^N \left( a[i] * ln(T)^{i-1} \right) \]

\[ ln(kappa) = \sum_{i=1}^N \left( b[i] * ln(T)^{i-1} \right) \]

Usage
Property Description
muCoeffs<8> Dynamic viscosity polynomial coefficients
kappaCoeffs<8> Thermal conductivity polynomial coefficients

Example of the specification of the transport properties: 

    transport
    {
        muCoeffs<8>     ( 1000 -0.05 0.003 0 0 0 0 0 );
        kappaCoeffs<8>  ( 2000 -0.15 0.023 0 0 0 0 0 );
    }

The polynomial expressions are evaluated as so:

\[ \mu = 1000 - 0.05 ln(T) + 0.003 ln(T)^2 \]

\[ \kappa = 2000 - 0.15 ln(T) + 0.023 ln(T)^2 \]

Note
  • Dynamic viscosity polynomial coefficients evaluate to an expression in [Pa.s], but internally uses [Pa.s/kmol].
  • Thermal conductivity polynomial coefficients evaluate to an expression in [W/m/K], but internally uses [W/m/K/kmol].
