Bingham plastic fluid
WebNov 5, 2024 · Bingham fluid is a material characterized by a yield stress; it flows with a constant plastic viscosity when an applied shear stress exceeds the yield stress, and does not flow otherwise. Such a flow has many practical applications such as transport of sewage, underground drainage, oil and fresh concrete/cement in pipes or pumping systems. WebDec 23, 2024 · The Bingham Plastic Model is the most widely used mathematical rheological model in the oil field. All data are generated from the 600 and 300 readings on a VG Meter. The model assumes that the …

WebFeb 19, 2024 · Bingham plastic is a non-Newtonian fluid that exhibits time-dependent rheological behaviour, so the viscosity of the fluid changes over time. This means that it will flow more easily when exposed to higher … WebNov 9, 2024 · Bingham plastic fluid medium has a higher viscosity and yield stress than normal media, which might prevent the mixing of the culture medium and limit the transportation of substrate and oxygen. Generally, pluripotent stem cells generate their energy via glycolysis, which does not require oxygen, so their oxygen requirement is low.
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 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 equation valid for all flow regimes: See more In fluid flow, it is a common problem to calculate the pressure drop in an established piping network.
