Class
    Foam::polynomialTransport

Description
    Transport package using polynomial functions for \c mu and \c kappa.

Usage

    \table
        Property        | Description
        muCoeffs<8>     | Dynamic viscosity polynomial coefficients
        kappaCoeffs<8>  | Thermal conductivity polynomial coefficients
    \endtable

    Example of the specification of the transport properties:
    \verbatim
    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 );
    }
    \endverbatim

    The polynomial expressions are evaluated as so:

        \f[
            \mu    = 1000 - 0.05 T + 0.003 T^2
        \f]

        \f[
            \kappa = 2000 - 0.15 T + 0.023 T^2
        \f]
