Detailed Description

Standard power-law generalised Newtonian viscosity model.

The power-law model provides a function for viscosity, limited by minimum and maximum values $\nu_{\min}$ and $\nu_{\max}$ respectively.

Kinematic viscosity [m^2/s]

\[ \nu = k\gamma^{n - 1}, \nu_{\min} \le \nu \le \nu_{\max} \]

Example specification:

     viscosityModel powerLaw;

     nuMax      1e-3;
     nuMin      1e-5;
     k          1;
     n          0.5;
