Cessation of Newtonian circular and plane Couette flows with wall slip and non-zero slip yield stress
(2017)We solve analytically the cessation flows of a Newtonian fluid in circular and plane Couette geometries assuming that wall slip occurs provided that the wall shear stress exceeds a critical threshold, the slip yield stress. ...

Unsteady circular Couette flow of a Bingham plastic with the Augmented Lagrangian Method
(2010)Numerical simulations are undertaken for unsteady flows of an ideal Bingham fluid in a circular Couette viscometer. The main difficulties in such simulations are caused by the non-differentiability of the constitutive ...

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