Bingham plastic non-newtonian fluid
WebA 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 the handling of slurries.

WebThe non-Newtonian fluids can be divided into two groups: (1) fluids without yield stress τ0 and the flow curve passes through the origin (as presented in Figure 6.3) and (2) fluids that exhibit yield stress τ0 and flows when the shear rate exceeds a value τ0. In this section, the non-Newtonian flow behavior without yield stress is presented.

WebBingham Plastic Example. Drilling mud has to be pumped down into an oil well that is 8000 ft deep. The mud is to be pumped at a rate of 50 GPM to the bottom of the well and back to the surface through a pipe having an effective diameter of 4 in. The pressure at the bottom of the well is 4500 psi. The viscosity of a shear thickening fluid, or dilatant fluid, appears to increase when the shear rate increases. Corn starch suspended in water ("oobleck", see below) is a common example: when stirred slowly it looks milky, when stirred vigorously it feels like a very viscous liquid. A familiar example of the opposite, a shear thinning fluid, or pseudoplastic flui…
