Abstract
A comparison of aggregate properties grown via three aggregation schemes– diffusion-limited cluster-cluster aggregation (DLCA), diffusion limited aggregation (DLA), and percolation–is presented. For a statistically significant number of aggregates grown via these three schemes, their volume fractions versus radii of gyration are compared against their structure factors. Results show that independent of aggregate size, the different methods of aggregate formation yielded the same power law behaviors. The only distinguishing feature between the three aggregation schemes was the scaling of the structure factor.
