Carreau fluid

Carreau fluid is a type of generalized Newtonian fluid where viscosity, $mu\_\{operatorname\{eff$, depends upon the shear rate, $dot\; gamma$, by the following equation:

:$mu\_\{operatorname\{eff(dot\; gamma)\; =\; mu\_0\; left(1+left(lambda\; dot\; gamma\; ight)\; ^2\; ight)\; ^\; \{frac\; \{n-1\}\; \{2$

Where: $mu\_0$, $lambda$ and "n" are material coefficients.

At low shear rate ($dot\; gamma\; ll\; 1/lambda$)Carreau fluid behaves as a Newtonian fluid and at high shear rate ($dot\; gamma\; gg\; 1/lambda$) as a power-law fluid.

The model was first proposed by Pierre Carreau.
