Witryna23 lis 2010 · The shear stress data were evaluated in the shear rate range of 0.01 s −1 to 500 s −1, and thus, modeled using the Herschel–Bulkley model Eq. 5. The Herschel–Bulkley model comprises the Newton, Bingham, and Ostwald-de-Waele (power law) models and is being widely used for describing the rheological properties … WitrynaThe viscous friction inside the foam was evaluated to analyze the stress, τ V, based on the Herschel–Bulkley model . (5) This model expresses the viscosity of a general non-Newtonian fluid and describes the shear behavior of a foam when bubbles do not slip on the surface of a frictional substrate.

The Herschel–Bulkley fluid is a generalized model of a non-Newtonian fluid, in which the strain experienced by the fluid is related to the stress in a complicated, non-linear way. Three parameters characterize this relationship: the consistency k, the flow index n, and the yield shear stress . The consistency is a simple constant of proportionality, while the flow index measures the degree to which the fluid is shear-thinning or shear-thickening.
