Witryna22 sty 2009 · Modeling Herschel-Bulkey Model. Hi guys, I am trying to model Herschel-Bulkey Model in fluent. [Specifically Bingham Plastic whose shear stress - rate relation is given by: τ = τo + ηÏ where τ is the shear stress. As you can see it is a function of the shear rate. However I want to have a constant value for my apparent viscosity.
Witryna6 mar 2024 · 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 [math]\displaystyle{ \tau_0 }[/math].The … WitrynaI am trying to model a process in which there is a flow of non-newtonian Herschel-Bulkley fluid. to derive equations of pressure drop, wall shear stress and drag …
