Shear-Thickening Fluids (Dilatant)
These fluids improve their viscosity when subjected to emphasize. Think about a mix of cornstarch and water. When stirred gently, it flows comparatively simply. Nevertheless, strike it rapidly, and it hardens, performing virtually like a stable. The impression forces the particles to squeeze collectively extra tightly, creating friction and growing viscosity. That is the precept used when making an attempt to skip throughout a pool of cornstarch and water.
Shear-Thinning Fluids (Pseudoplastic)
In contrast to shear-thickening fluids, these lower in viscosity when stress is utilized. Examples embody paint, ketchup, and blood. The extra you stir or agitate them, the extra simply they stream. This property makes them helpful in purposes the place you want a cloth to be thick when nonetheless, however simply spreadable when in use.
Different notable varieties embody viscoelastic fluids, which exhibit each viscous and elastic properties (consider foolish putty) and thixotropic fluids, which turn out to be much less viscous over time when a continuing stress is utilized. Every of those totally different behaviors is because of the totally different bodily properties of the fluid itself.
