*More importantly, what does it matter? If you're sizing or selecting pumps , mixers, or any other type of equipment that applies shear to fluid, these are all terms you should know. A Newtonian fluid's viscosity remains constant, no matter the amount of shear applied for a constant temperature..*

Successful characterization of viscosity is key in determining if a fluid is Newtonian or non-Newtonian. Each unique material has its own behavior when subjected to flow, deformation or stress. Depending on their viscosity behavior as a function of shear rate, stress, deformation history Some examples of Newtonian fluids include water, organic solvents, and honey. For those fluids viscosity is only dependent on temperature.

This means that the viscosity of Newtonian fluids will remain a constant see Figure 2 no matter how fast they are forced to flow through a pipe or channel i. An exception to the rule is Bingham plastics, which are fluids that require a minimum stress to be applied before they flow. A great example of this kind of behavior is mayonnaise.

A common example of shear thickening fluids is a mixture of cornstarch and water. You have probably seen examples of this on TV or the internet, where people can run over this kind of solutions and yet, they will sink if they stand still. Fluids are shear thinning if the viscosity decreases as the shear rate increases.

Shear thinning fluids, also known as pseudo-plastics, are ubiquitous in industrial and biological processes. Common examples include ketchup, paints and blood. For all these fluids, the shear rate at the walls i. Successful characterization of viscosity is key in determining if a fluid is Newtonian or non-Newtonian, and what range of shear rates needs to be considered for an specific application. Therefore, proper characterization of viscosity must be carried out at a shear rate that is relevant to the specific process.

Applied Rheology Volume 21 Issue 5 Abstract: The influence of short fibre addition on the rheological behaviour of different non-Newtonian fluids is investi-gated experimentally. Two types of suspending fluids are considered: power-law shear thinning fluids and yield-stress shear-thinning babyky. Morrison, Michigan Tech U.

A Non-Newtonian fluid is a fluid whose flow viscosity properties differ from those of Newtonian fluids, described by Sir Isaac Newton. Newtonian fluids [1] [2] have a constant viscosity flow. Viscosity, measures a fluids ability to resist gradual deformation by shear or tensile stresses, in other words, is a propriety that measures how easily a fluid move: if a fluid has high viscosity, then the fluid will move slower; if a fluid has low viscosity, then it will move faster. For example: fluids like water, have lower viscosity unlike fluids such as honey or syrup. For Newtonian fluids , changing the force you apply to the fluid will not change their viscosity.

Rheological constitutive equations of non-Newtonian liquids are discussed in detail in Chap. Skip to main content. This service is more advanced with JavaScript available.

A non-Newtonian fluid is a fluid that does not follow Newton's law of viscosity , i. In non-Newtonian fluids, viscosity can change when under force to either more liquid or more solid. Ketchup , for example, becomes runnier when shaken and is thus a non-Newtonian fluid. Many salt solutions and molten polymers are non-Newtonian fluids, as are many commonly found substances such as custard , [1] honey , [1] toothpaste , starch suspensions, corn starch , paint , blood , melted butter , and shampoo. Most commonly, the viscosity the gradual deformation by shear or tensile stresses of non-Newtonian fluids is dependent on shear rate or shear rate history. Some non-Newtonian fluids with shear-independent viscosity, however, still exhibit normal stress-differences or other non-Newtonian behavior.
