Non-Newtonian Viscosities

Bird et al. (Bll), 1960 Brief theoretical treatments of various cases of film flow (on cone, with variable viscosity, non-Newtonian liquids, etc.) and of heat and mass transfer to films. 

Newtonian Flow Fluid flow that obeys Newton s law of viscosity. Non-Newtonian fluids may exhibit Newtonian flow in certain shear rate or shear stress regimes. See also Newtonian Fluid.

Hi) Shear Dependence of Viscosity, Non-Newtonian Behavior The presence of reinforcing fillers also increases the non-Newtonian behavior of elastomers. This effect is mainly due to the fact that the incorporation of fillers in elastomers decreases the volume of the deformable phase. As discussed in the following text, this decrease is not limited to the actual volume of the filler, but must also include the existence of occluded mbber. So, when filled mixes are submitted to shear forces, because of the lower deformable volume, the...

This still applies when taking the law of intrinsic viscosity (Non-Newtonian behavior of the melt, viscosity dependent on the shear rate) into account. Not included, however are the cooling effects, forming of solidified layers in the cooled mold and heat dissipation during the flow process. These influences can only be sufficiently considered in a simulation system by newly determining the conditions from element to element.
