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 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 ...
Steady Herschel-Bulkley fluid flow in three-dimensional expansions
(2001)
In this paper we study steady flow of Herschel-Bulkley fluids in a canonical three-dimensional expansion. The fluid behavior was modeled using a regularized continuous constitutive relation, and the flow was obtained ...
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 ...
