Cessation of Couette and Poiseuille flows of a Bingham plastic and finite stopping times
(2005)We solve the onedimensional cessation Couette and Poiseuille flows of a Bingham plastic using the regularized constitutive equation proposed by Papanastasiou and employing finite elements in space and a fully implicit ...

Flow development in compression of a finite amount of a Bingham plastic
(2007)The flow and shape evolution during the compression of a finite amount of a Bingham plastic is investigated by means of numerical simulations. The problem relates to the popular compression test used for the rheological ...

Inertial, viscous and yield stress effects in Bingham fluid filling of a 2D cavity
(2001)The present study concentrates on Bingham fluid filling of a 2D cavity and examines the relative importance of inertial, viscous and yield stress effects on the filling profile. The results presented are obtained using ...

Injection molding of dilute and semidilute fiber suspensions
(Publ by ASME, 1992)The focus of this paper is unsteady flow of semidilute fiber suspensions in complex geometries. These flows are typical of injection molding problems in which the raw material in granular form, usually plastic resin mixed ...

On the stability of the simple shear flow of a JohnsonSegalman fluid
(1998)We solve the timedependent simple shear flow of a JohnsonSegalman fluid with added Newtonian viscosity. We focus on the case where the steadystate shear stress/shear rate curve is not monotonic. We show that, in addition ...

Processing of semisolid materials using a shearthickening Bingham fluid model
(Publ by ASME, 1994)Recently the importance of processing metals and metal matrix composites in semisolid state is growing rapidly. Performing the shape making operations in the semisolid state provides a better opportunity to control the ...

The timeindependent, compressible Poiseuille and extrudateswell flows of a Carreau fluid with slip at the wall
(2003)We solve the timedependent, compressible Poiseuille and extrudateswell flows of a shearthinning fluid that obeys the Carreau constitutive model, using finite elements in space and a fullyimplicit scheme in time. Slip ...

Article
Viscoplastic flow development in a channel with slip along one wall
(2017)The flow development of a Herschel–Bulkley fluid in a horizontal channel is considered assuming that slip occurs only on the upper wall due to slip heterogeneities. Hence, the velocity profile is allowed to be asymmetric ...
