Friction and the oscillatory motion of granular flows
Lydie Staron
This contribution reports on numerical simulations of 2D granular flows on erodible beds. The broad aim is to investigate whether simple flows of model granular matter exhibits spo…
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…
Non-symmetric localized fold of a floating sheet
Marco Rivetti
An elastic sheet lying on the surface of a liquid, if axially compressed, shows a transition from a smooth sinusoidal pattern to a well localized fold. This wrinkle-to-fold transit…
Electrostatic interactions mediated by polarizable counterions: weak and strong coupling limits
Vincent Démery, David S. Dean, Rudolf Podgornik
We investigate the statistical mechanics of an inhomogeneous Coulomb fluid composed of charged particles with static polarizability. We derive the weak- and the strong-coupling app…
An approach to anomalous diffusion in the n-dimensional space generated by a self-similar Laplacian
Thomas Michelitsch, Gérard Maugin, Andrzej F. Nowakowski +2
We analyze a quasi-continuous linear chain with self-similar distribution of harmonic interparticle springs as recently introduced for one dimension (Michelitsch et al., Phys. Rev.…
A "well-balanced" finite volume scheme for blood flow simulation
Olivier Delestre, Pierre-Yves Lagrée
We are interested in simulating blood flow in arteries with a one dimensional model. Thanks to recent developments in the analysis of hyperbolic system of conservation laws (in the…
