A fluid that departs from the classic linear newtonian relation between stress and shear rate. In a strict sense, a fluid is any state of matter that is not a solid, and a solid is a state of matter that has a unique stress-free state. A conceptually simpler definition is that a fluid...
Figure 2. Scheme of typical non-Newtonian behavior. Red curve: Bingham fluid, σy≠ 0, n = 1. Fluids with no yield stress: yellow curve, Newtonian fluid, n = 1; blue curve, shear thinning (pseudoplastic) fluid, n = 0.8; green curve, shear-thickening (dilatant) fluid, n = 1.2. ...
Prandtl assumed that for a Newtonian fluid: Reδ=v∗δν=const. Analogously, we assume that for a pseudoplastic fluid: (14.71)Repδ=v∗2−nδnρK8(6n+2n)nconst. Using Eqs. (14.71) and (14.33), the thickness of the laminar sublayer can be expressed as: (14.72)δ=(RepδRep)...
Synonyms Complex fluids ; Polymer solutions ; Rheology ; Suspensions Definition Non-Newtonian fluids exhibit complex flow behavior, typically because they contain additives such as polymers or particles that alter the response of the fluid. Unlike Newtonian fluids, which have constant viscosity (...

This exploration reports the analysis of thermal and species transportation to yields manifesting non㎞ewtonian material flowing over the linear stretching sheet. Phenomena of heat transport are presented via Cattaneo–Christov heat flux definition. Mass transportation is modeled by engaging the traditional...
The power law model of non Newtonian fluid represents the fluid phase according to the drill mud definition. The particles and the fluid properties and specifications are selected from previous works. The results characterized the scenario of solid in liquid settling behavior obtained from Chein's ...
The objective of this chapter is to introduce and to illustrate the frequent and wide occurrence of non-Newtonian fluid behaviour in a diverse range of applications, both in nature and in technology. Starting with the definition of a non-Newtonian fluid, different types of non-Newtonian characteri...
