Abstract
Random aggregates of hard spheres can be formed either by aggregation or by dynamic reorganization. The resulting two broad families of aggregates present different geometrical structures that have not been studied in a systematic fashion to this day. We investigate various structural indicators (contact coordination number, Delaunay tetrahedra, Voronoi polyhedra, pair distribution functions,…) of aggregates belonging to these two broad families, building them by using Lubachevsky–Stillinger algorithm for the aggregates formed by dynamic reorganization and a family of aggregation algorithms. This comparison takes place over a large range of packing fraction, from 0.370 up to 0.640. This allows distinguishing significant differences between random aggregates formed by aggregation or in a dynamic manner, or according to the contacting status of the spheres. Various structural commonalities are also investigated by different structural indicators. An evaluation of the parameters that could distinguish between all studied aggregates is also proposed.
