Bingham plastic - Wikipedia
WebFor laminar flow of a Bingham plastic in a horizontal pipe of radius R, the velocity profile is given as u (r) = (ΔP/4? L) (r2 − R2) + (?y /? ) (r − R), where ΔP/L is the constant pressure drop along the pipe per unit length, ? is the dynamic viscosity, r is the radial distance from the centerline, and ?y is the yield stress of Bingham plastic. WebFlow of a Bingham Plastic in a Couette Viscometer Figure 1 shows the flow of a fluid between inner and outer cylinders in a Couette Viscometer and its velocity profile. Figure 2 shows the stress acting on the fluid element for such fluid flow. In a Couette Viscometer, there is an angular flow of a fluid of viscosity 𝜇 between two cylinders of 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 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 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 different pipe-flow problems, viz. calculating the pressure drop for evaluating … See more Darby–Melson equation In 1981, Darby and Melson, using the approach of Churchill and of Churchill and Usagi, developed an expression to get a single friction factor … See more high cpu zoom
