Journal ArticleDOI
Bouncing motion of spherical particles in fluids
TL;DR: In this article, the bouncing motion of solid spheres onto a solid plate in an ambient fluid which is either a gas or a liquid was investigated and the coefficient of restitution e was measured as a function of the Stokes number, St, ratio of the particle inertia to the viscous forces.
Journal ArticleDOI
Granular avalanches in fluids.
TL;DR: Three regimes of granular avalanches in fluids are put in light depending on the Stokes number St which prescribes the relative importance of grain inertia and fluid viscous effects and on the grain/fluid density ratio r.
Journal ArticleDOI
Shear instability of two-fluid parallel flow in a Hele–Shaw cell
Philippe Gondret,Marc Rabaud +1 more
TL;DR: In this paper, the authors study the parallel flow in a Hele-Shaw cell of two immiscible fluids, a gas and a viscous liquid, driven by a given pressure gradient.
Journal ArticleDOI
Influence of confinement on granular penetration by impact
TL;DR: The presence of close lateral walls reduces the penetration depth of impacting spheres into a granular medium contained in a finite cylindrical vessel, and the characteristic distance for these lateral wall effects is found to be of the order of one sphere diameter.
Journal ArticleDOI
Experiments on the motion of a solid sphere toward a wall: From viscous dissipation to elastohydrodynamic bouncing
TL;DR: In this article, the authors investigate experimentally the motion of a macroscopic (non-Brownian and noncolloidal) solid sphere falling under gravity into a viscous liquid toward a solid wall, and observe the transition from a nonbouncing to a bouncing regime when increasing the Stokes number St which characterizes the particle inertia.
