Cessation of viscoplastic Poiseuille flow with wall slip
(2014)We solve numerically the cessation of axisymmetric Poiseuille flow of a HerschelBulkley fluid under the assumption that slip occurs along the wall. The Papanastasiou regularization of the constitutive equation is employed. ...

Combined effects of compressibility and slip in flows of a HerschelBulkley fluid
(2013)In this work, the combined effects of compressibility and slip in Poiseuille flows of HerschelBulkley fluids are investigated. The density is assumed to obey a linear equation of state, and wall slip is assumed to follow ...

Article
Shear rejuvenation, aging and shear banding in yield stress fluids
(2009)The purpose of this work is to simulate shear rejuvenation and aging effects in shear thinning yield stress fluids in a typical rotational rheometer and to provide a common framework to describe the behavior of yield stress ...

Viscoplastic Poiseuille flow in a rectangular duct with wall slip
(2014)We solve numerically the Poiseuille flow of a HerschelBulkley fluid in a duct of rectangular cross section under the assumption that slip occurs along the wall following a slip law involving a nonzero slip yield stress. ...

Wall shear rates in circular couette flow of a HerschelBulkley fluid
(2009)The objective of this work is to study quantitatively the errors introduced by the standard Newtonian and powerlaw assumptions used in the determination of the material properties of viscoplastic fluids from circular ...

Weakly compressible Poiseuille flows of a HerschelBulkley fluid
(2009)In this work, we derive approximate semianalytical solutions of the steady, creeping, weakly compressible plane and axisymmetric Poiseuille flows of a HerschelBulkley fluid. Since the flow is weakly compressible, the ...
