WebWhere du/dy is the shear rate (or velocity gradient), τ is the applied shear stress, τo is the yield stress, K is the consistency coefficient, and n is the flow behavior index. The … 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.
