Quasi-Three-Dimensional Simulation of Equal-Sized Sphere Packing Based on Rhombohedral Tetragonal Ordination

Abstract

Random packing phenomena of equal sized spheres (of micron or submicron size) were simulated assuming a quasi-three-dimensional packing structure based on rhombohedral tetragonal ordination. In the simulation, the probability of particle movement through a packed layer was determined with simple rules in accordance with the contact pattern of particles. The calculated average void fraction was 0.37, a value which agreed with that of random close packing and many previous experimental results with equal spheres.
