Cessation of Couette and Poiseuille flows of a Bingham plastic and finite stopping times
(2005)We solve the one-dimensional 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 instabilities of Herschel-Bulkley fluids
(2003)We investigate numerically the interactions of two-dimensional jets of Bingham plastic and Herschel-Bulkley fluids with a vertical surface at a distance from the die exit. This problem simulates the early stages of filling ...

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

On the transition to turbulence of a viscoplastic fluid past a confined cylinder: A numerical study
(2015)Three-dimensional direct numerical simulations of a Bingham fluid flowing past a confined circular cylinder have been used in order to investigate viscoplastic effects in the wake-transition regime. The case of a cylinder ...
