Diffusion-Limited Aggregation: a Model for Computer Simulation of Fractal Growth
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
Diffusion-limited aggregation (DLA) is a model for computer simulation of particle aggregation.
It is known to generate aggregates with a characteristic appearance with
many branches spreading in all directions and a specic fractal dimension. The aggregates
resemble many created by processes in nature such as crystallization, uid ow and
growth of bacteria colonies. In this thesis the DLA model and a few variations of it are
investigated to illuminate its exibility. The variations investigated are a noise-reduced
model, introducing surface tension and increasing the ux of particles. The fractal dimension
is calculated in each case and compared to the results of similar experiments,
both simulated and real.
