FIG. 1. Sketch of the experimental setup.
FIG. 2. Number of grains N(t) vs. time t for V = 9.6 mm/s and different initial packing fractions C i
FIG. 4. Packing fraction C in the outlet region vs. time t. We observe that the temporal evolution of C depends strongly on its initial value C i (V = 9.6 mm/s).
FIG. 6. Velocity V g of the grains upstream of the outlet vs.
