Bingham plastic fluid examples
WebBingham plastic Several examples are clay suspensions, drilling mud, toothpaste, mayonnaise, chocolate, and mustard. The surface of a Bingham plastic can hold peaks when it is still. By contrast Newtonian fluids have flat featureless surfaces when still. WebBingham plastics are fluids which remain rigid under the application of shear stresses less than a yield stress, Ty, but flow like a. simple Newtonian fluid once the applied shear …

WebThe Bingham plastic model describes the flow characteristics of different kinds of mud and is described mathematically as: T - shear stress, γ - shear rate, YP - yield point and PV - plastic viscosity. Fluids that obey this model are called Bingham plastic fluids. PV should be low by minimizing colloidal solids to enable fast drilling while YP ... WebA Bingham plastic is a viscoplastic material that behaves as a rigid body at low stresses but flows as a viscous fluid at high stress. It is named after Eugene C. Bingham who proposed its mathematical form. It is used as a common mathematical model of mud flow in drilling engineering, and in the handling of slurries.

WebJan 7, 2024 · Familiar examples of such fluids are fruit purées, mayonnaise, mustard, and ketchup. These two first fluids (dilatant and pseudoplastic) can be mathematically described by eqn (1.4), known as the Ostwald–de Waele model or power law model. In this equation k represents the consistency coefficient and n represents the flow behavior index.
