Log polynomial

Dynamic viscosity, $\mu$ [Pa.s]

$$\ln(\mu) = \sum_{i=1}^N \left( c_i \ln(T)^{i-1} \right)$$

Thermal conductivity, $\kappa$ [W/mK]

$$\ln(\kappa) = \sum_{i=1}^N \left( c_i \ln(T)^{i-1} \right)$$

Thermal diffusivity, $\alpha_h$ [kg/ms]

$$\alpha_h = \frac{\kappa}{c_p}$$

Usage

The logPolynomial transport model is defined using the entries:

transport
{
    muCoeffs<8>     ( <c1> <c2> <c3> <c4> <c5> <c6> <c7> <c8> );
    kappaCoeffs<8>  ( <c1> <c2> <c3> <c4> <c5> <c6> <c7> <c8> );
}

Where

• muCoeffs<8> : Polynomial coefficients (x8)
• kappaCoeffs<8> : Polynomial coefficients (x8)
