Detailed Description

Cross-Power law generalized Newtonian viscosity model.

The strain rate coefficient can be specified either as the constant m or the critical stress level at the transition to shear thinning tauStar if tauStar is provided:

Kinematic viscosity [m^2/s]

$\‍[ \nu = \nu_\infty + \frac{(\nu_0 - \nu_\infty)}{1 + (m\gamma)^n} \‍]$

or

$\‍[ \nu = \nu_\infty + \frac{(\nu_0 - \nu_\infty)} {1 + \left(\frac{\nu_0\gamma}{\tau^*}\right)^n} \‍]$

Example specification:

     viscosityModel CrossPowerLaw;

     nuInf      10;
     m          0.4;
     n          3;
