Étude sur la forme d'un tas de billes dans un silo bidimensionnel
We experimentally confirm an expression derived by Boutreux and de Gennes for the shape of a granular pile filling a two-dimensional silo. The analytical formula is retrieved from a model of kinks using the vertical translational invariance of the heap surface. We also look at the dependence of the shape on the energy of the particles poured into the cell.
