WebJul 20, 2024 · Based on the flow behavior index, $n$: if $0 < n < 1$: The fluid shows pseudo-plastic or shear-thinning behavior. Here a smaller value of $n$ means a greater degree of shear-thinning. if $n=1$: The fluid shows Newtonian behavior. if $n>1$: The fluid shows dilatant or shear-thickening behavior with a higher value of $n$ resulting in ... WebFeb 1, 1995 · The elongational viscosity of two different cooked cornmeal dough was determined as a function of moisture content (55-70% wet basis) and differences in cornmeal structure using the lubricated squeezing flow technique. When the flow regime was not governed by the viscoelastic effect, cooked cornmeal dough could be described … Webflow behavior depends on the history of what forces were applied to the fluid. Such fluids include thixotropic (shear-thinning over time) and rheopectic (shear-thickening over time) types. Viscoelastic fluids exhibit elastic or solid-like behavior when forces are first applied, and then transition to viscous flow under continuing force. crystal resonator翻译
