These fluids have a linear relationship between viscosity and … WebNon-settling slurries can be modeled with Power Law, Bingham Plastic or Homogeneous Scale-Up correlations and will thus behave differently than common Newtonian fluids. Non-settling, non-Newtonian fluid modeling is part of the standard AFT Fathom and AFT Impulse (for waterhammer) packages. AFT Fathom and AFT Impulse can model settling solid ...
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 $${\displaystyle \tau _{0}}$$.
