Fluids give and flow under stress. Newtonians are the simplest of fluids, and they are characterized by the property that the velocity gradient at a point is proportional to the shear stress at that point, thus $$({\rm{Shear\;rate}})\alpha ({\rm{shear\;stress}})\;\;{\rm{or}}\;\;{{du} \over {dy}}\alpha \tau$$ All other fluids are called non ...

A model equation for Non‐Newtonian fluids
Mathematical Methods in the Applied Sciences, 1981AbstractA one‐dimensional model for the equations of motion of a “simple fluid” according to Noll is proposed. An exterior problem for the model equation is solved by means of a transform method.

Sound Propagation in Non-Newtonian Fluids
Journal of Applied Mechanics, 1973A perturbation analysis is applied to the basic hydrodynamic equations and developed to determine the non-Newtonian effects of a small-signal plane wave propagating through a viscous fluid which is continuous, homogeneous, and isotropic. With the emphasis on liquids, the analysis is applied to the case of a Powell-Eyring fluid (which specializes to the

Viscous fingering in non-Newtonian fluids
Journal of Fluid Mechanics, 2002We study the viscous fingering or Saffman–Taylor instability in two different dilute or semi-dilute polymer solutions. The different solutions exhibit only one non-Newtonian property, in the sense that other non-Newtonian effects can be neglected. The viscosity of solutions of stiff polymers has a strong shear rate dependence.

How could you characterize a liquid? You could start with its color, maybe talk about its smell or taste (watch out!) and consider its acidity (lime juice or soap). But sooner or later you will think about the liquid’s viscosity. The viscosity quantifies what we use to call a “thick” or “thin” liquid.

Entrance Flows of Non-Newtonian Fluids
Transactions of the Society of Rheology, 1973The creeping flow of a Powell-Eyring fluid through a sudden tubular contraction is considered, and finite difference solutions of the vorticity transport and stream function equations are obtained for a range of contraction ratios, fluid properties, and apparent shear rates.

Abstract A new branch of fluid mechanics,Rheology, has rapidly been developed. It deals with non-Newtonian fluids which behave anomalously in comparison with Newtonian fluids. The anomaly is the variation in viscosity with the applied stress while the viscosity is constant for all Newtonian fluids.
