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

Experimental observations show that the viscosity, as measured by viscosimeters, is constant for some fluids as water or honey, that are called Newtonian fluids (see Sect. 1.6, p. 21).

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.

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 ...

Incompressible mixtures of newtonian fluids
International Journal of Engineering Science, 1966Abstract The constitutive equations are derived for an incompressible mixture of Newtonian fluids using an entropy production inequality; they involve the introduction of an arbitrary hydrostatic pressure. The derivation of Fick's Law of diffusion for an incompressible mixture of ideal fluids is presented together with an examination of helical flow,

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.

Simple Non-Newtonian Fluid Flows
1980Publisher Summary This chapter focuses on simple non-Newtonian fluid flows. Water and air, the most important fluids for life, are Newtonian fluids. However, there are many fluid materials of importance in nature and technology that are non-Newtonian fluids. Certain aspects of the flow behavior of such non-Newtonian fluids are markedly different from
