Simulations of aggregation in 2D. A study of kinetics, structure and topological properties

Colloidal aggregation in 2D has been studied using off-lattice simulations. Structural, kinetic and topological properties, these last using the Voron oi construction, have been analysed in diffusion-limited cluster aggregatio n (DLCA) and reaction-limited cluster aggregation (RLCA). The simulations s how dynamic scaling of the cluster-size distribution for large sizes and ti mes. it has been observed that when the system reaches dynamic scaling some topological properties become stationary. Furthermore, kinetic and topolog ical aspects are related among them. (C) 2000 Elsevier Science B.V. All rig hts reserved.
