Ultimately, a non-Newtonian fluid will change under force to be either more liquid or more solid. We’ve outlined all the steps and supplies needed to create your own super-liquid below, but be ...
Viscoelasticity is a type of non-Newtonian flow, characterizing a material that acts as a viscous liquid over a long time period but as an elastic solid over a short time period. [7] Because its apparent viscosity increases directly with respect to the amount of force applied, Silly Putty can be characterized as a dilatant fluid. [5]
In a non-Newtonian fluid, the relation between the shear stress and the shear rate is different. The fluid can even exhibit time-dependent viscosity. Therefore, a constant coefficient of viscosity cannot be defined. Although the concept of viscosity is commonly used in fluid mechanics to characterize the shear properties of a fluid, it can be ...
The episode followed the original format of the program, supported by extra internet resources, with Hutton and Morrison performing experiments related to cereal, including making homemade cornflakes and cornflour-based non-Newtonian fluid. The episode was praised by the channel's followers. [15]

Classification of fluids with shear stress as a function of shear rate: Pseudoplastic, Bingham plastic and Bingham pseudoplastic all show reduction in apparent viscosity with increasing shear rate. In rheology , shear thinning is the non-Newtonian behavior of fluids whose viscosity decreases under shear strain .
The viscous behavior of a liquid can be either Newtonian or non-Newtonian. A Newtonian liquid exhibits a linear strain/stress curve, meaning its viscosity is independent of time, shear rate, or shear-rate history. Examples of Newtonian liquids include water, glycerin, motor oil, honey, or mercury. A non-Newtonian liquid is one where the ...
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. A dilatant is a non-Newtonian fluid where the shear viscosity increases with applied shear stress.
