Effect of rectangular container's sides on porosity for equal-sized sphere packing

Containers have a crucial role in determining the porosity of packed spheres. The new gravitational sphere packing method is applied for loose packed particles based on Monte-Carlo simulation. The model is simulated in a cylindrical container by considering the effect of the wall. A new method is employed to examine the porosity of spheres in the inner part of the cylinder without the effect of boundaries, where spheres can be packed in different rectangular containers to show the structure of packing within sides of different sizes.

The loosely packed mono-sized spheres have symmetric porosity values within the different virtual rectangular containers. It is shown that spherical particles have high potential to be packed inside the square container with lowest value of the porosity. Subsequently, spherical particles can be packed by high value of the porosity within the rectangular container with significant difference in its sides.Figure optionsDownload as PowerPoint slideHighlights
