Class
    Foam::logPolynomialTransport
 
Description
    Transport package using polynomial functions of the natural logarithm of
    temperature for the natural logarithm of dynamic viscosity and thermal
    conductivity:
 
    \verbatim
        log(mu) = muCoeffs[0] + muCoeffs[1]*log(T)
           + muCoeffs[2]*sqr(log(T)) + muCoeffs[3]*pow3(log(T))
           + muCoeffs[4]*pow4(log(T)) + muCoeffs[5]*pow(log(T), 5)
           + muCoeffs[6]*pow(log(T), 6) + muCoeffs[7]*pow(log(T), 7)
 
        log(kappa) = kappaCoeffs[0] + kappaCoeffs[1]*log(T)
           + kappaCoeffs[2]*sqr(log(T)) + kappaCoeffs[3]*pow3(log(T))
           + kappaCoeffs[4]*pow4(log(T)) + kappaCoeffs[5]*pow(log(T), 5)
           + kappaCoeffs[6]*pow(log(T), 6) + kappaCoeffs[7]*pow(log(T), 7)
    \endverbatim
 
    The polynomial function is templated on the order of the polynomial which
    defaults to 8.
 
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
