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.
The flow surrounded by the porous medium is governed by the Bingham model, and the flow in the porous medium is governed by the Darcy's law.
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.
Reader should be aware that the Bingham model
classification for Yuma King does not imply nor infer that the resource potential at Yuma King will be similar in size or grades to that at the Bingham Canyon Mine.
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 Herschel-Bulkley model is a generalized form of the Bingham model
, where the linear shear-rate dependence is replaced by a power-law behaviour.
