Particle percolation through a porous medium

Abstract : In this paper we study transport of particles due to gravity in a porous medium simulated by a packing of large beads. We determine the dependency of the mean transit time for different percolating particle batches and for different packing heights. We compare our results with numerical simulations based on the Discrete Element Method to extend experimental studies and to analyze the part play by the coefficient of restitution and the aspect ratio between the two size of beads.
