Bingham model

Bing·ham mod·el

(bing'ăm),
a model representing the flow behavior of a Bingham plastic, in the idealized case.

Bingham,

E.C., U.S. chemist, 1878-1945.
Bingham flow - the flow characteristics exhibited by a Bingham plastic.
Bingham model - a model representing the flow behavior of a Bingham plastic, in the idealized case.
Bingham plastic - a material that, in the idealized case, does not flow until a critical stress (yield stress) is exceeded, and then flows at a rate proportional to the excess of stress over the yield stress.

Similarly, magnetic liquid also conforms to Bingham model [14].
As far as Bingham model is adequate to characterize rheological properties of fresh mortar and concrete, characterization of rheological properties of cement paste demands more complex models.
That proves that Bingham model is adequate to describe rheological properties of mortars.
To describe concrete flow behavior, both yield stress and plastic viscosity, as defined by the Bingham model, are key properties that should be determined.
The slope of this resulting curve according to the Bingham model will give the plastic viscosity and the intercept at zero shear rate will give the yield stress.
The resulting data were analyzed based on the Bingham model, whereby a straight line was fit to the plot of torque, T(N * m), versus rotation speed, N (rad/s):
The values of the yield stress and plastic viscosity are deduced from these flow curves, as described by the Bingham model, by calculating the intercept of the linear fit for the yield stress and the slope as the plastic viscosity.
The Herschel-Bulkley model is a generalized form of the Bingham model, where the linear shear-rate dependence is replaced by a power-law behaviour.
One of the models for yield stress fluids is Bingham model.
The flow in the channel is assumed to be governed by Bingham model.
The flow in the channel is described by Bingham model, whereas the flow in the permeable bed is according to Darcy's law.
