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 • 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. 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 WebBingham Plastic - Friction Factor Formulae Friction Factor Formulae In fluid flow, it is a common problem to calculate the pressure drop in an established piping network.
WebBingham Plastic Fluid. This web application calculates pressure drop in a straight pipe due to flow of a non-Newtonian Bingham plastic fluid. where, D is pipe inside diameter, V is …
WebThe solution methodology is general in scope, does not put any restrictions on the Bingham number and thus. Steady flow of the viscoplastic Bingham and Herschel-Bulkley (H-B) fluids in tubes of noncircular cross-section is investigated analytically. The solution methodology is general in scope, does not put any restrictions on the Bingham ... WebThe Bingham Plastic model uses a constant value for plastic viscosity, meaning a value for μ∞ of 0 would result in a Newtonian fluid. Some fluids may see Bingham …
WebThe friction factor for a Bingham plastic can be calculated for any Reynolds number from the equation. f = ( fLm + fTm ) 1/m where, fL is laminar flow friction factor and fT is …
WebFluids that have a linear shear stress/shear strain relationship but require a finite yield stress before they begin to flow (the plot of shear stress against shear strain does not pass through the origin) are called Bingham plastics. Several examples are clay suspensions, drilling mud, toothpaste, mayonnaise, chocolate, and mustard. try hotel mattressWebIn chemical engineering, the following definition of Fanning friction factor is popular [1]: f ¼ F k =ðAKÞ ð1Þ where F k is the force on the object due to relative motion between object and fluid, A is the characteristic area (usually wet- ted surface area), K is the kinetic energy per unit volume and f is the friction factor. tryhrtyhWebThe Bingham plastic model is the most common rheological model used in the drilling industry.
