Shear Thickening Fluid's (STFs) are examples of Non-Newtonian fluids, a rare set of materials and fluids who's behavior deviates from Newton's law - … Modern paints are examples of pseudoplastic materials. When modern paints are applied, the shear created by the brush or roller will allow them to thin and wet out the surface evenly. Once applied, the paints regain their higher viscosity, which avoids drips and runs. Ketchup is a prominent example of a shear … See more In rheology, shear thinning is the non-Newtonian behavior of fluids whose viscosity decreases under shear strain.

In view of the large volume of the mixtures considered in the experiments, all the shear-thinning fluids were prepared using tap water.

WebThis makes blood a shear-thinning fluid. Other examples of shear thinning fluids are paint, ketchup, and whipped cream. Paint flows quickly while it is being spread (sheared) on a wall, but once you stop moving it, the paint does not flow down the wall because its viscosity increases. Ketchup and whipped cream flow quickly out of their ... WebAt a given shear rate, the viscosity evolves towards a steady-state value. A non-thixotropic shear-thinning fluid, in contrast, would (almost) immediately reach its steady-state viscosity in response to a change in shear rate. ...

WebThixotropy. Thixotropy is the property of some non-newtonian pseudoplastic fluids to show a time-dependent change in viscosity; the longer the fluid undergoes shear stress, the lower its viscosity. A thixotropic fluid is a fluid which takes a finite amount of time to attain equilibrium viscosity when introduced to a step change in shear rate.
