Detailed Description

template<class Thermo, int PolySize = 8>
class Foam::logPolynomialTransport< Thermo, PolySize >

Transport package using polynomial functions of the natural logarithm of temperature for the natural logarithm of dynamic viscosity and thermal conductivity: 

    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)

The polynomial function is templated on the order of the polynomial which defaults to 8.

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);
    }
