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…
This the DEM code developed in FORTRAN standard. It can perform DEM simulations for spherical particles. This DEM code benefits from various optimization algorithms giving rise to its execution speed, though it not parallel. Therefore, simulating tens of thousand particles within a reasonable time is possible. This code can be…
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…
