Characterising Components and Flocculation Structure of Sediment in a Diffusion-Limited Cluster-Cluster Aggregation Model

K. A. Hawick

Abstract

A simulation model based upon diffusion limited cluster-cluster aggregation is developed with an applied drift force so that sedimentary behaviour of aggregating clusters can be studied. Metrics for the size and number of aggregates and their compactness and nature are applied to numerical simulations on three-dimensional systems. The model is parameterised in terms of particulate density and a dimension-less Peclet number which are shown to both have critical values and corresponding regimes of differing behaviour. We discuss the potential and limitations of the model for simulating flocculation in water treatment systems.

Keywords: simulation; diffusion-limited cluster-cluster aggregation; component cluster; complex system
