Bingham plastic fluid examples
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 ... WebBingham fluid A viscous fluid that possesses a yield strength which must be exceeded before the fluid will flow. Most lava flows are examples of Bingham fluids. When an …

WebTypical examples for pseudo-plastic fluids are polymer solutions and similar solutions of high molecular weight substances. At low shear rates, these liquids will experience the formation of shear stress. The shear stress results in the reordering of the molecules in order to reduce the overall stress.

WebFlorida State University In materials science, a 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 … See more Figure 1 shows a graph of the behaviour of an ordinary viscous (or Newtonian) fluid in red, for example in a pipe. If the pressure at one end of a pipe is increased this produces a stress on the fluid tending to make it move … See more The material is an elastic solid for shear stress $${\displaystyle \tau }$$, less than a critical value $${\displaystyle \tau _{0}}$$. Once the critical shear stress (or "yield stress") is exceeded, the material flows in such a way that the shear rate, ∂u/∂y (as defined in the See more Although an exact analytical solution of the Buckingham–Reiner equation can be obtained because it is a fourth order polynomial … See more • Bagnold number • Bernoulli's principle • Bingham-Papanastasiou model • Rheology See more In fluid flow, it is a common problem to calculate the pressure drop in an established piping network.
