Detailed Description

Bird-Carreau generalized Newtonian viscosity model.

The Bird-Carreau-Yasuda form is also supported if the optional a coefficient is specified. a defaults to 2 for the Bird-Carreau model.

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

Kinematic viscosity [m^2/s]

or

Example specification for a polymer:

     viscosityModel BirdCarreau;

     nuInf       0;
     tauStar     90;
     n           0.5;
