WebJan 15, 2002 · Analytical formulations for determining the size of the imaginary channel for flows of Newtonian, power law fluids, and Bingham plastics under prescribed tape-casting conditions are presented. Mathematical expressions for obtaining velocity profiles and flow rates are included, which are then used to estimate the thickness of a dried ceramic tape.
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 $${\displaystyle \tau _{0}}$$.
