Intermittent dry granular flow in a vertical pipe
Yann Bertho, Frederique Giorgiutti-Dauphine, Jean-Pierre Hulin
The intermittent compact flow of glass beads in a vertical glass pipe of small diameter is studied experimentally by combining particle fraction, pressure, and air and grain flow r…
Dense bubble flow in a silo: an unusual flow of a dispersed medium
Yann Bertho, Christophe Becco, Nicolas Vandewalle
The dense flow of air bubbles in a two-dimensional silo (through an aperture D) filled with a liquid is studied experimentally. A particle tracking technique has been used to bring…
Influence of humidity on granular packings with moving walls
Y. Bertho, Th. Brunet, F. Giorgiutti-Dauphine +1
A significant dependence on the relative humidity H for the apparent mass (Mapp) measured at the bottom of a granular packing inside a vertical tube in relative motion is demonstra…
