WebDec 23, 2024 · The most popular are the Bingham Plastic, Power Law, and Herschel-Bulkley. The Bingham Plastic model is the simplest. It introduces a nonzero shear stress at zero shear rate: Me = T/y = Mp + /y where mp is dubbed the plastic viscosity and t0 the yield stress, that is, the stress required to initiate flow. mp, is analogous to m in the …

WebFeb 2, 2024 · Thus, the greater the Bingham number, the higher is the Reynolds number up to which the creeping flow conditions apply for spheres moving in Bingham plastic fluids. As mentioned previously, the three parameter Herschel-Bulkley fluid model gives a somewhat better fit of the fluid rheology than the Bingham model. WebThe Improved Bingham model and Herschel–Bulkley model are similar, both have high R2 (all R2 > 0.99), regardless of W/S ratios. And the Improved Bingham model has higher R2 than Herschel–Bulkley model. This means that the Improved Bingham model is more suitable than Herschel-Bulkley model to fit the flow curves of Kaolinite clay.

In colloid systems, phase separation during flow leads to shear thinning. In polymer systems such as polymer melts and solutions, shear thinning is caused by th…

The Herschel–Bulkley fluid is a generalized model of a non-Newtonian fluid, in which the strain experienced by the fluid is related to the stress in a complicated, non-linear way. Three parameters characterize this relationship: the consistency k, the flow index n, and the yield shear stress . The consistency is a simple constant of proportionality, while the flow index measures the degree to which the fluid is shear-thinning or shear-thickening. Ordinary paint is one example of a shear-t…
