Discharge of a silo in hypergravity

Last year, we performed a series of experiments to investigate the flow of an assembly of non-cohesive spherical grains in high gravity conditions. We studied the flow of beads out of a  silo that was loaded in one of the … Continue reading

Breaking arches with vibrations : the role of defects

A characteristic feature of granular materials is the existence of arches. These force chains alter the isotropy of a granular packing and can stop the flow of grains during the discharge of a silo. Therefore, the knowledge of the arches … Continue reading

Interlocking of non-convex particles

Grain sizes and shapes are relevant features when studying the physical properties of granular systems. This is the reason why many industries focus their efforts into technologies for controlling / measuring particle morphologies. In a recent article, we demonstrate that … Continue reading

Physics of ice cube melting

During summertime, a physical phenomenon can be observed in a fresh drink. Consider your favorite cocktail in a long drink glass you filled with a lot of ice cubes. The packing of the ice blocks is slowly melting. Suddenly, this … Continue reading

Hypergravity at ESTEC

Our team has recently performed a series of experiments on silo discharge in low gravity environments. The paper is now published in Phys. Rev. E (see below). We prove that gravity plays an important role on the behavior of granular … Continue reading
