Bingham fluid example
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") … See more Although an exact analytical solution of the Buckingham–Reiner equation can be obtained because it is a fourth order polynomial equation in f, due to complexity of the solution it is … See more In fluid flow, it is a common problem to calculate the pressure drop in an established piping network. Once the friction factor, f, is known, it becomes easier to handle … See more Darby–Melson equation In 1981, Darby and Melson, using the approach of Churchill and of Churchill and Usagi, developed … See more • Bagnold number • Bernoulli's principle • Bingham-Papanastasiou model • Rheology See more WebA 10.5-ppg Herschel-Bulkley fluid with a consistency index of 20 cp equivalent, a flow behavior index of 0.8, and a yield stress of 5 lb/100 ft2 is circulating at 250 gpm in an 8¾-in-diameter wellbore.
