In particular, a growth mechanism has been implemented in a MC code able to describe diffusion-limited cluster aggregation (DLCA) and reaction-limited cluster aggregation (RLCA). The clusters fractal dimension is evaluated as a function of parameters such as the ratio of growth and aggregation rates, the occupied volume fraction and the particles sticking probability. The present model represents an interesting tool able to provide the fractal dimension to be employed in deterministic models to properly describe the simultaneous growth and agglomeration processes.
