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 Voronoi construction, have been analysed in diffusion-limited cluster aggregation (DLCA) and reaction-limited cluster aggregation (RLCA). The simulations show dynamic scaling of the cluster-size distribution for large sizes and times. It has been observed that when the system reaches dynamic scaling some topological properties become stationary. Furthermore, kinetic and topological aspects are related among them.
