The model and extensions applied to granular material in silo with inserts

Samuel K Irvine, Luke A Fullard, Daniel J Holland +3

Granular material is often handled using silos with inserts in industrial processes to prevent "rat-holing" and similar behaviour, optimise mixing behaviour, and prevent segregatio…

Capturing the dynamics of a two orifice silo with the μ(I) model and extensions

Samuel K Irvine, Luke A Fullard, Daniel J Holland +3

Granular material in a silo with two openings can display a `flow rate dip', where a non-monotonic relationship between flow rate and orifice separation occurs. In this paper we st…

Frictional weakening induced by cohesion: the numerical case of cohesive granular failures

Lydie Staron, Laurent Duchemin, Anais Abramian +1

The failure of 2D numerical cohesive granular steps collapsing under gravity are simulated for a large range of cohesion. Focussing on the cumulative displacement of the grains, an…

A pressure impulse theory for hemispherical liquid impact problems

Julien Philippi, Arnaud Antkowiak, Pierre-Yves Lagrée

Liquid impact problems for hemispherical fluid domain are considered. By using the concept of pressure impulse we show that the solution of the flow induced by the impact is reduce…

One-dimensional Arterial Network Model for Bypass Grafts Assessment

Arthur Ghigo, Salam Abou Taam, Xiaofei Wang +2

We propose an arterial network model based on 1D blood hemodynamic equations to study the behavior of different vascular surgical bypass grafts in case of an arterial occlusive pat…

Towards a new friction model for shallow water equations through an interactive viscous layer

François James, Pierre-Yves Lagrée, Hoang-Minh Le +1

The derivation of shallow water models from Navier-Stokes equations is revisited yielding a class of two-layer shallow water models.An improved velocity profile is proposed, based…

The granular silo as a continuum plastic flow: the hour-glass vs the clepsydra

Lydie Staron, Pierre-Yves Lagrée, Stéphane Popinet

The granular silo is one of the many interesting illustrations of the thixotropic property of granular matter: a rapid flow develops at the outlet, propagating upwards through a de…

Reproduction of hypopnea phenomenon using a physical and numerical model

Franz Chouly, Annemie Van Hirtum, Pierre-Yves Lagrée +2

Obstructive sleep apnea syndrome is now considered as a major health care topic. An in-vitro setup which reproduces and simplifies upper airway geometry has been the basis to study…

Granular Pressure and the Thickness of a Layer Jamming on a Rough Incline

Christophe Josserand, Pierre-Yves Lagrée, Daniel Lhuillier

Dense granular media have a compaction between the random loose and random close packings. For these dense media the concept of a granular pressure depending on compaction is not u…
