We study the outflow of soft particles through quasi-two-dimensional hoppers with both experiments and simulations. The experiments utilize spheres made with hydrogel, silicone rubber, and glass. The hopper chamber has an adjustable exit width and tilt angle (the latter to control the magnitude of gravitational forcing). Our simulation mimics the experiments using purely two-dimensional soft particles with viscous interactions but no friction. Results from both simulations and experiments…

Clogging and avalanches in quasi-two-dimensional emulsion hopper flow.
We experimentally and computationally study the flow of a quasi-two-dimensional emulsion through a constricting hopper shape. Our area fractions are above jamming such that the droplets are always in


Clogging of soft particles in two-dimensional hoppers.
The results suggest that prior studies using hard particles were in a limit where the role of softness is negligible, which causes clogging to occur with significantly larger openings, and that with stiffer particles or a weaker gravitational force, clogging is easier.
Silo outflow of soft frictionless spheres
Outflow of granular materials from silos is a remarkably complex physical phenomenon that has been extensively studied with simple objects like monodisperse hard disks in two dimensions (2D) and hard
Flow in an hourglass: particle friction and stiffness matter
Granular flow out of a silo is studied experimentally and numerically. The time evolution of the discharge rate as well as the normal force (apparent weight) at the bottom of the container is
Intermittent flow and transient congestions of soft spheres passing narrow orifices.
This work studies the statistics of silo discharge of soft hydrogel spheres and finds the outflow is found to become increasingly fluctuating and even intermittent with decreasing orifice size, and with decreasing fill height.
Clogging of granular materials in silos: effect of gravity and outlet size.
The role of the driving force in the clogging of inert particles passing through a constriction is disclosed and the probability that an arch gets destabilized is obtained, which is shown to primarily depend on the square root of the kinetic energy.
Effect of hopper angle on granular clogging.
The probability of clogging can be reduced by three orders of magnitude by increasing the hopper angle, and for very large hopper angles, the avalanche size grows with the outlet size stepwise, in contrast to the case of a flat-bottom silo for which 〈s〉 grows smoothly with D.
Flow of magnetic repelling grains in a two-dimensional silo
During a typical silo discharge, the material flow rate is determined by the contact forces between the grains. Here, we report an original study concerning the discharge of a two-dimensional silo
Granular discharge and clogging for tilted hoppers
We measure the flux of spherical glass beads through a hole as a systematic function of both tilt angle and hole diameter, for two different size beads. The discharge increases with hole diameter in
Pore-size dependence and slow relaxation of hydrogel friction on smooth surfaces
It is shown that when hydrogel is dragged along a smooth, wet solid surface, the friction is controlled by hydrodynamic interactions within the gel’s polymer network, and is inversely proportional to the characteristic pore size.
Statistics of shear-induced rearrangements in a two-dimensional model foam.
It is found that for dry foams, there is a well-defined quasistatic limit at low shear rates where localized rearrangements occur at a constant rate per unit strain, independent of both system size and dissipation mechanism.
