WebJan 16, 2024 · To investigate whether the slurry exhibited Bingham pseudoplastic behavior, rheological measurement was carried out using a rotational rheometer … Bingham plastics require a critical shear stress to be exceeded in order to start flowing. This behaviour is usually seen in polymer/silica micro- and nanocomposites, where the formation of a silica network in the material provides a solid-like response at low shear stress. See more 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 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 require a non-zero … See more • Shear thickening – Material in which viscosity increases with the rate of shear strain • Non-Newtonian fluid – Fluid that does not follow … 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 shearing. In colloid systems, See more Modern paints are examples of pseudoplastic materials. When modern paints are applied, the shear created by the brush or roller … See more • The Great Ketchup Mystery • NASA - The Physics of Whipped Cream NASA April 25, 2008 References: See more

WebMar 20, 2024 · Bingham plastic fluid's flow behaviour index (or plastic viscosity) is a measure of the resistance of a fluid to flow. It is a dimensionless number that describes the behavior of a fluid when … WebNov 3, 2016 · The first category of fluids are the ones that exhibits pseudoplastic behavior and can be modeled as a power-law fluid, and the second category are the ones that possesses a yield stress and can be modeled as a Bingham fluid.

WebAug 2, 2024 · According to Fig. 7, the samples prepared at 160 °C fully match the Bingham pseudoplastic model. Based on these results, the suitable temperature for injection of sample in the injection molding device is 160 °C, since the feed has Bingham pseudoplastic fluid behavior. Webrelationship has been for shear thinning and for Bingham plastic fluids and Figure 3-5 Variation of critical value of the Reynolds number with 𝒏′. has been found to be accurate. Over the range of shear thinning behavior encountered in practice, 0.2 ≤ 𝒏′ < 1.0, the critical value of 𝑹 ′ is in the range 2100 ≤ 𝑹 ′ ≤ 2400.
