WebFeb 9, 2024 · The 300- and 600-rpm shear rates are generally greater than annulus shear rates, resulting in calculated shear stresses greater than the actual values. Although the Bingham model is commonly accepted in practice, a model such as the Power Law would be more descriptive, particularly when the fluid is in turbulence. WebThe Bingham plastic model is the most common rheological model used in the drilling industry. This model is a two parameter model that includes yield stress and plastic …
WebBingham plastic is a material that behaves as rigid body at low stresses but flows as a viscous fluid at high stress. This behaviour is exhibited by slurries, suspensions of solids in liquids, paints, emulsions, foams, etc. Bingham model is described by following relation. where, τ is shear stress, γ is shear rate, τo is called minimum yield ... WebFly ash originating from the hazardous waste treatment facility in Dorog (Table 13) behaved as Bingham plastic over 10% of volumetric concentration and it was a time dependent rheopectic fluid. Even though the Dorog fly ash was Bingham plastic , Indian red mud was determined to be Newtonian over a short time period; however its shear resistance ...
