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 ...
Solution of viscoplastic flows with the finite volume / multigrid method
(National Technical University of Athens, 2013)
We investigate the performance of the finite volume method in solving viscoplastic flows. The square lid-driven cavity flow of a Bingham plastic is chosen as the test case and the constitutive equation is regularised as ...
Performance of the finite volume method in solving regularised Bingham flows: Inertia effects in the lid-driven cavity flow
(2014)
We extend our recent work on the creeping flow of a Bingham fluid in a lid-driven cavity, to the study of inertial effects, using a finite volume method and the Papanastasiou regularisation of the Bingham constitutive model ...
Thixotropic flow past a cylinder
(2014)
We study the flow of a thixotropic fluid around a cylinder. The rheology of the fluid is described by means of a structural viscoplastic model based on the Bingham constitutive equation, regularised using the Papanastasiou ...
