202 Shear Thickening (Dilatant)
Shear thickening (dilatant) is a non-Newtonian fluid where the shear viscosity increases with applied shear stress.
A Newtonian fluid’s viscosity remains constant, no matter the amount of shear applied for a constant temperature. Examples include water, mineral oil, gasoline, and alcohol. Conversely, a dilatant is a non-Newtonian fluid whose viscosity increases when shear is applied (Figure 202.1). Dilatant behavior is typically observed in fluids with a high concentration of small solid particulates suspended within a liquid. An example of a dilatant fluid is a suspension of corn flour dissolved in water, which creates a substance called oobleck.
The general phenomenon of dilatancy ...
