Bingham fluid definition
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, … 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 … 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 equation valid for all flow regimes: See more WebAug 26, 2024 · A fluid is a substance that flows under the influence of shear forces. Liquids, gases, and plasmas are all examples of fluids. Plastic solids are considered fluids to some extent. Fluids can be classified as one of the following based on the relationship between shear stress and the rate of strain and its derivatives: Newtonian fluid

WebAn exception to the rule is Bingham plastics, which are fluids that require a minimum stress to be applied before they flow. These are strictly non-Newtonian, but once the flow starts they behave essentially as … WebBingham Plastic Models: Bingham plastic fluids can be defined as the fluids that have a linear stress-strain relationship and which require a finite yield stress before they start to …

WebFor a power law fluid, the entry length is determined based on the classical definition. In order to obtain the corrected Reynolds number Re*, Ito’s method is employed in this study. It is shown that the entry lengths of Newtonian, Bingham and power law fluids are correlated by the same equations in the range of Re* 20. WebIn contrast to a Bingham fluid, a pseudoplastic fluid is a fluid that increases viscosity as force is applied. A typical example is a suspension of cornstarch in water with a concentration of one to one. This cornstarch behaves like water when no force is applied; however, it is solidified as force is applied.
