Cessation flows of bingham plastics with slip at the wall
(National Technical University of Athens, 2013)We use finite elements in space and a fully implicit scheme in time in order to solve the cessation of axisymmetric Poiseuille flow of a Bingham plastic under the assumption that slip occurs along the wall. The Papanastasiou ...

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. ...

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

Stopping times in cessation flows of Bingham plastics with slip at the wall
(2012)We solve numerically the cessation of axisymmetric Poiseuille flow of a Bingham plastic assuming that slip occurs along the wall. A power-law expression is used to relate the wall shear stress to the slip velocity. The ...
