Webh is associated with the relative plastic viscosity [ 21 , 22 ]. Other models, such as the Ostwald de Waele and the Herschel–Bulkley models of equations given by Equations (3) and (4), may be used to evaluate the rheological activity of cement paste in particular: τ = kγn (3) τ = τ 0 + kγn (4) 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.
