Description
Transport package using the Andrade function for the natural logarithm of
dynamic viscosity and thermal conductivity of liquids:
\verbatim
log(mu) = muCoeffs[0] + muCoeffs[1]*T + muCoeffs[2]*sqr(T)
+ muCoeffs_[3]/(muCoeffs_[4] + T)
log(kappa) = kappaCoeffs[0] + kappaCoeffs[1]*T + kappaCoeffs[2]*sqr(T)
+ kappaCoeffs_[3]/(kappaCoeffs_[4] + T)
);
\endverbatim
