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 nonzero 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 in a square duct with wall slip
(2015)We solve numerically the cessation of the pressuredriven Poiseuille flow of a Bingham plastic under the assumption that slip occurs along the wall following a generalized Navierslip law involving a nonzero slip yield ...

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. ...

Article
Newtonian flow in a triangular duct with slip at the wall
(2013)We consider the Newtonian Poiseuille flow in a tube whose crosssection is an equilateral triangle. It is assumed that boundary slip occurs only above a critical value of the wall shear stress, namely the slip yield stress. ...

Article
Newtonian Poiseuille flows with slip and nonzero slip yield stress
(2013)The Newtonian Poiseuille flow is considered for various geometries, under the assumption that wall slip occurs above a critical value of the wall shear stress known as, the slip yield stress. In the axisymmetric and planar ...

Article
Slip yield stress effects in startup Newtonian Poiseuille flows
(2013)Analytical solutions are derived for various startup Newtonian Poiseuille flows assuming that slip at the wall occurs when the wall shear stress exceeds a critical value, known as the slip yield stress. Two distinct regimes ...

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. ...
