摘要
An iterative procedure according to which new spheres are inserted between existing-ones is realized for computer simulation of dense granular systems. The method is based on the rigorous geometrical Voronoi-Delaunay approach generalized for pore volume analysis inside an ensemble of polydisperse hard spheres [N.N. Medvedev, Dokl. Akad. Nauk 337, 767 (1994) [Dokl. Phys. Chem. 337, 157 (1994)]]. Models with packing fraction eta similar to 0.9 are constructed. The particle size distribution and fractal nature df the packings are investigated. The fractal dimension D = 2.45 is obtained.
