Three: Conical Hopper

The flow of spherical particles in a conical hopper with the cone angle 45° is studied. Density and size of particles are 2500 kg/m³ and 9 mm, respectively. Diameter of the hopper is 20 cm and diameter of the exit orifice is 8 cm. A wide, flat wide plate is located 14 cm below the exit orifice on which a pile of discharged particles is formed. The simulation consists of two stages: the first stage is filling of hopper in which the exit gate is closed, the second stage is discharging the hopper in which the exit gate is removed and particles are allowed to exit the hopper under the gravity.
