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.

[11] investigated the flow of a Newtonian fluid and Bingham fluid in a Rayleigh step bearing.
Therefore, the material can be modeled as a Bingham fluid to predict the final shape.

A common example of a visco-plastic material is the Bingham fluid [10, 38].
Hence the study of Bingham fluid flow through a conical tube with permeable wall is of considerable importance in medicine.
Such a Bingham fluid [19] has a so-called yield stress ([[tau].sub.0]).
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] 22.2% and 0 [less than or equal to] [chi] [less than or equal to] 25.0%, respectively.
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.
This behaviour occurs primarily because the foam fluid is a time-varying Bingham fluid, resulting in the viscosity increasing from 4360 MPa-s at 60 s to 4451 MPa-s at 360 s, causing the foam fluid flows to slow.
When m is equal to zero, the Newtonian shear rate is obtained, but for m values approaching infinity the Bingham fluid occurs.
Afterward flow will occur, and the fluid becomes a Bingham fluid having a yield stress (1, 7-9).
