Wall Effect in 3D Simulation Of Same Sized Particles Packing

In this paper, the effects of container size on the porosity of random loose packing of mono size particles have been investigated using an Event Dynamics (ED) based model. Simultaneous effects of square container walls on particles packing and their order are also investigated. Our simulation results indicate higher container size will increase the total packing factor and high density regions which can be attributed to decrease of low density regions near the walls and also the order imposed by them. By growing packing container size, reproducibility of packing factor values increases which is another indication of more packing randomness.
