Pseudoplastic non-newtonian fluid
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. 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 … See more • The Great Ketchup Mystery • NASA - The Physics of Whipped Cream NASA April 25, 2008 References: See more WebFluid mechanics Fluids Statics ·Dynamics Archimedes' principle ·Bernoulli's principle Navier–Stokes equations Poiseuille equation ·Pascal's law Viscosity (Newtonian ·non-Newtonian) Buoyancy ·Mixing ·Pressure …

A friction factor correlation for laminar, hydrodynamically … The viscosity of a shear thickening fluid, or dilatant fluid, appears to increase when the shear rate increases. Corn starch suspended in water ("oobleck", see below) is a common example: when stirred slowly it looks milky, when stirred vigorously it feels like a very viscous liquid.
