ABSTRACT

The porosity of 0.377 far away from the wall of cylindrical containers is deduced based on three possible stable and quasi-stable packed configurations, and the probability of each configuration is assumed the same. A model considering the bulk porosity 0.377 and the influence of column-to-sphere diameter ratio D/d is proposed to predict the radial porosity distribution in cylindrical containers packed with uniformly sized spheres. The model is validated by available experimental data in the literature and the present experimental work.
