摘要: Abstract The free settling model is presented for aggregates of multilevel structure. Primary aggregates, formed by primary particles, join together to produce larger objects, which are treated as monomers bigger clusters until the final aggregate obtained. objects at each structural level have specific size and fractal dimension. obtained velocity normalized that particles can be expressed dependent on ratio their sizes total number particles. Some experimental data quoted support dependence. They kaolin flocs two-level structure measured light-scattering technique test.
