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.

A fluid can be defined as a material that deforms continually under the application of an external force. In other words, a fluid can flow and has no rigid three-dimensional structure. An ideal fluid may be defined as one in which there is no friction.

In this chapter we concentrate on a large class of problems arising from the dynamics of incompressible non-Newtonian fluids with nonstandard rheology. By non-Newtonian fluids we mean here fluids which do not satisfy Newton’s law of viscosity, i.e. viscosity is constant and independent of stress.

New types of robots inspired by biological principles of assembly, locomotion, and behavior have been recently described. In this work we explored the concept of robots that are based on more fundamental physical phenomena, such as fluid dynamics, and their potential capabilities. We report a robot made entirely of non-Newtonian fluid, driven by shear

Publisher Summary This chapter reviews non-Newtonian lubrication. Newton's law of viscous shear states that the shear stress is proportional to the velocity gradient, or loosely, to the sliding speed divided by the film thickness. Under elastohydrodynamic lubrication (EHL) conditions, where the fluid viscosity is enormously higher by a factor of at ...

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 ...
