WebFeb 25, 2024 · The Bingham Plastic model is used primarily to compute friction pressure associated with laminar flow. This restriction is based on its inability to accurately … WebThe Bingham plastic model does not accurately predict fluid flow behavior at low shear rates but is useful for continuous monitoring and treating of drilling fluids. Unlike the Bingham plastic model, the power-law model assumes a non - linear relationship between the shear stress and the shear rate.
WebIn the Bingham plastic model, flow will not begin until the shear stress attains a minimum value, the yield stress, after which the flow is similar to that of a Newtonian fluid because the viscosity is constant and does not vary with shear rate. Pseudoplasticity, or shear thinning, is a non-Newtonian behavior that is desirable for drilling fluids.
