The Herschel-Bulkley model describes describes η, the apparent viscosity of the fluid as: Webwhere p characterizes the flow behavior: p < 1 for shear-thinning (pseudo-plastic) flow behavior and p > 1 for shear-thickening (dilatants) flow behavior. For ideal viscous …
WebApr 14, 2024 · Due to the zeta potential heterogeneity at the obstacle surface, vortical flow is formed near the obstacle surface, which can significantly improve the mixing efficiency. The results show that, the mixing efficiency can be improved by increasing the obstacle surface zeta potential, the flow behavior index, the obstacle height, the EDL thickness.

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.
