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 ...
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 ...
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 ...
