Pseudoplastic non-newtonian fluid

WebMay 26, 2024 · Conversely, pseudoplastic are non-Newtonian fluids that get thinner under a similar condition. Although their viscosity is variable; however, while one gets thicker under pressure, the other gets thinner with the same pressure. Furthermore, these non-Newtonian fluid categories can be broken down as follows – rheopectic and thixotropic. WebApr 17, 2024 · Non-Newtonian fluids may be dependent on shear rate (force) or time.

WebShear thinning, or pseudoplastic, fluids are characterized by consistency and flow behavior indices, K and n. These values are determined experimentally by measuring the fluid viscosity at different shear rates, satisfying the power law relationship: (16-9) Where: = apparent viscosity = consistency index = shear rate, s −1 = flow behavior index WebINTRODUCTION The largest and probably most important class of non-Newtonian fluids are those which exhibit pseudoplastic flow, i.e., which show a decrease in viscosity with increasing rate of shear. Familiar examples are found in paint systems, printing inks, and disperse systems generally. WebThixotropy is a time-dependent shear thinning property.

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 time-dependent effects, such as thixotropy. Shear thinning is the most common type of non … 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 geometries within the fluid rearrange to facilitate 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 … See more • Shear thickening – Material in which viscosity increases with the rate of shear strain • Non-Newtonian fluid – Fluid that does not follow Newton's Law of Viscosity See more Modern paints are examples of pseudoplastic materials.
