Hyper-redundant manipulators can be fragile, expensive, and limited in their flexibility due to
the distributed and bulky actuators that are typically used to achieve the precision and …

During the past decades, notable improvements have been achieved in the understanding
of static and dynamic properties of granular materials, giving rise to appealing new concepts …

We present experimental results on the effect that inserting an obstacle just above the outlet
of a silo has on the clogging process. We find that, if the obstacle position is properly …

The clogging of a stream bed has a significant impact on the exchange of water between a
river and groundwater, known as hyporheic exchange. Clogging issues in orifices …

We measure the fraction F of flowing grain configurations that precede a clog, based on the
average mass discharged between clogging events for various aperture geometries. By …

Retention barriers are a common countermeasure for mitigating the hazards associated with
debris flows. With the aim to regulate sediment transport and retain large boulders, which …

The three-dimensional jamming of neutrally buoyant monodisperse, bidisperse, and
tridisperse mixtures of particles flowing through a restriction under fluid flow has been …

We present experimental results on the shape of arches that block the outlet of a two-
dimensional silo. For a range of outlet sizes, we measure some properties of the arches …

Fluids introduced into a reservoir for stimulation typically take the path of least resistance
and therefore frequently go into areas where there are open flow paths. In many cases …

In this work, we examine a quasi-2D silo that clogs due to the spontaneous formation of
stable arches. We validate a numerical scheme comparing the morphology of clogging …
