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
