Bingham plastic

[′biŋ·əm ‚plas·tik]
(fluid mechanics)
A non-Newtonian fluid exhibiting a yield stress which must be exceeded before flow starts; thereafter the rate of shear versus shear stress curve is linear.

A common example of a visco-plastic material is the Bingham fluid [10, 38].
In this paper, we consider the augmented formulation of the Bingham fluid, further referred to as the ABF problem, introduced in [3].
Hence the study of Bingham fluid flow through a conical tube with permeable wall is of considerable importance in medicine.
Bird et al [5] investigated the Bingham fluid flow in a rigid circular tube.
According to the description of the Bingham rheological model, the TBAB CHS, including types A and B, is verified as Bingham fluid in the range of 0 [less than or equal to] [chi] [less than or equal to] 22.
For the Bingham fluids, the effective viscosity [[mu].
In view of these, the effect of magnetic field on the peristaltic pumping of a Bingham fluid through a porous medium in an inclined channel is studied under long wavelength and low Reynolds number assumptions.
We consider the peristaltic flow of a conducting Bingham fluid flow through a porous medium in a channel of half-width a.
Afterward flow will occur, and the fluid becomes a Bingham fluid having a yield stress (1, 7-9).
When m is equal to zero, the Newtonian shear rate is obtained, but for m values approaching infinity the Bingham fluid occurs.
As the constant time m is related to the particles concentration C in the carrier fluid, we can say according to the figure 5, that the paraffin slurry behaves as Newtonian fluid for low concentration values and as a Bingham fluid for higher values.
Concrete and mortar are generally accepted to be Bingham fluids [6].
