WebNewtonian Fluids Did you know that silly putty can be considered a fluid? Bingham Plastics act as a rigid body until a certain force is applied, then it acts as a liquid. Toothpaste is a Bingham Plastic. Pseudo-plastics (shear thinning) decrease in viscosity when more force is applied. Example of pseudo-plastics include: nail polish, 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 (called the shear stress) and the volumetric flow rate increases proportionally. However, for a … See more 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. 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. Once the friction factor, f, is … 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 • Rheology • Shear thinning See more Webτ = τo + μp γ where, τ is shear stress, γ is shear rate, τo is called minimum yield stress and μp is called plastic viscosity. Reynolds number for Bingham plastic fluid is defined as Re = D V ρ / μp where, D is pipe inside diameter, V is fluid velocity and ρ is fluid density. csu long beach gre code
