The velocity gradient in this zone was not affected by Newtonian viscosity, and it would be expected that the same should apply for non-Newtonian rheological properties.

TPVs and their nanocomposites exhibit Power Law type behavior without indication of any Newtonian viscosity plateau.

11 and 12 predict the existence of the upper Newtonian viscosity [eta][infinity] both for pseudoplastic and dilatant behavior, but it does not appear as the separate model parameter contrary to many other equations discussed later.
New Generalized Newtonian Fluid Models for Quantitative Description of Complex Viscous Behavior in Shear Flows
The peak [[alpha].sub.H] of the shear-thinning fluid is close to that of the highest Newtonian viscosity. In the low-frequency region, however, the [[alpha].sub.H] value is higher than that of Newtonian fluids.

Furthermore, the use of an effective Darcy's law by replacing the Newtonian viscosity by its shear-thinning counterpart may be also questionable, particularly for large injection rates where the most complex structures were reported.
Experimental and numerical analysis of the viscous fingering instability of shear-thinning fluids
Velocity profile predictions for the power-law viscosity model (n = 0.3) and Newtonian viscosity were much more similar for the relieved dies than for the unrelieved die.
