grown onto seed particles 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 markedly 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.
