Shear thickening suspensions - Principles and applications

Everyday experience teaches us that fluids resist being moved, and that this resistance varies greatly according to the nature of the fluid. For example, it's much harder to move a spoon through honey than through a glass of water. The physical quantity that characterizes this resistance is the fluid's viscosity. This is defined as follows. In the case of a simple shear flow, as shown in figure 1 a, a layer of fluid of thickness h is sheared between a fixed and a moving plate at constant speed U. In the stationary regime, the velocity profile is linear and allows the shear rate $\dot{\gamma }=U\text{/}h$...
