grown onto seed particles in both two and three dimensions using a new computer simulation.
The agglomeration process was controlled by varying the amount of diffusion influence in the
growth mechanism. The perimeter and density fractal dimensions of simulated agglomerates
comprising up to 800 particles were measured using three different automated techniques. The
perimeter dimension was found to increase with larger diffusion influence, whilst the density of the
structure, measured using the enclosing circles and radius of gyration methods, decreased as the
level of diffusion increased. The importance of these results to the characterisation of cake
filtration processes is discussed.
