Scaling Properties of Cluster and Particle Aggregation

Abstract

The model of cluster aggregation and several variants of it serve to describe different disordered aggregation processes and their scaling properties. Here, the basic model is introduced and its properties are briefly discussed. Some more recent results are then presented in more detail : simplifying features in high dimension, gelation in cluster aggregation, the role of reaction kinetics, the problem of cluster readjustment and the internal structure of clusters in relation to the growth process. Finally a film, produced to illustrate how clusters aggregate, is described.
