The uniform mixing of particles is crucial in many industrial
applications. In industries, most granular materials are nonspherical,
with ellipsoids being a common deviation from the sphere. The study
employs the DEM model to investigate the mixing of a binary mixture in a
vibrated packed bed with fixed amplitude and frequency. The study
explores the behavior of the binary mixture of coarse and fine
particles, with one particle being ellipsoid of aspect ratios (0.25-3.0)
and the other being a sphere. The subdomain mixing index quantifies the
mixing. The mixing of binary mixtures is determined by the aspect ratio
of coarse and fine particles. The mixing efficiency is indicated by the
average velocity of reference spherical particles, reflecting the
convection strength within the bed. The results show higher average
velocity in an ellipsoidal-sphere mixture than in a sphere-sphere
mixture. The DEM results are validated with an identical experimental
system.
