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 + ηύ where τ is the shear stress
τo is the yield stress η is the apparent viscosity ύ is the shear rate ] In fluent [Define > Materials> Viscosity> Herschel Bulkey] the input parameters for the apparent viscosity involves the following defination: η = (τo + K [ ύ " (τo/ o)])/ ύ where k is the consistency factor o is the yielding viscosity As you can see it is a function of the shear rate. However I want to have a constant value for my apparent viscosity. How can I do it? |
