Abstract
Packed beds of spheres are simulated through discrete element method in
cylinders with different geometric configurations of internal walls to
evaluate their effects on bed porosity. Numerical simulations are
validated using well-known literature data. Three containing systems,
namely concentric cylinders, angular walls, and a combination of both,
are generated. The resulting bulk porosities and porosity profiles of
the sphere beds are analyzed. The increase in porosity is proportional
to the incorporated wall support, that is, the combination of
cylindrical and angular inserts displays the greatest effect. The
sinusoidal porosity values near the inserted walls are exhibited. In
conclusion, the obtained behaviors and profiles can be used to explore
additional effects and further systems.
