WebExample. Determine the carrying capacity index with the following: Data: ... For highly viscous, shear-thinning fluids, where the flow behavior index is less than about 0.3, a cavern forms around the impeller. Outside the cavern, little or no mixing occurs and the fluid remains stagnant. With turbine impellers, the height to diameter ratio of ... 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. It is sometimes considered synonymous for pseudo-plastic behaviour, and is usually defined as excluding See more Some authors consider shear-thinning to be a special case of thixotropic behaviour, because the recovery of the microstructure of the liquid to its initial state will always require a non-zero … See more • The Great Ketchup Mystery • NASA - The Physics of Whipped Cream NASA April 25, 2008 See more Though the exact cause of shear thinning is not fully understood, it is widely regarded to be the effect of small structural changes within the fluid, such that microscale … See more • Shear thickening – Material in which viscosity increases with the rate of shear strain • Non-Newtonian fluid – Fluid that does not follow … See more

WebA dilatant ( / daɪˈleɪtənt /, / dɪ -/) (also termed shear thickening) material is one in which viscosity increases with the rate of shear strain. Such a shear thickening fluid, also known by the initialism STF, is an example of a non-Newtonian fluid. This behaviour is usually not observed in pure materials, but can occur in suspensions .

WebAug 16, 2024 · The study of rheology is motivated by the many fluids in nature and industrial applications which exhibit non-Newtonian behavior, i.e., a nonlinear relation between the shear stress and the shear rate; the relation between these macroscopic behaviors and the microstructure is often studied assuming suspensions of objects in a …
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 ...
