We investigate mixing mechanism in a rotating drum operating in rolling regime. To this end, a drum with the diameter of 0.2 m and depth of 0.03 m is half-filled with 19000 3-mm spherical particles. Rotation speed of the drum is 10 RPM. This rotation speed creates the cascading regime…
The flow of spherical particles in a conical hopper with the cone angle 45° is studied using DEM. Density and size of particles are 2500 kg/m3 and 9 mm, respectively. Diameter of the conical hopper is 20 cm and diameter of the exit orifice is 8 cm. A wide, flat…
In this DEM simulation, we create a random packed bed of spherical particles in a cylindrical container with the diameter of 15 cm and height of 20 cm. Particles are a mixture of spherical particles with similar density (2500 kg/m3) and uniform sizes distribution between 3 and 7.5 mm. In…
In this simulation, we create a random packed bed of particles (packed bed of spheres) in a cylindrical container with the diameter of 15 cm and length of 20 cm. To create this bed, 8000 7-mm spherical particles with the density of 2500 kg/m3 are used. In the followings, we…
