Optical and dynamical investigations of fractal clusters

The characterisation of particle shape has been an active research area and source of contention for over fifty years. In this paper we have reviewed the concept of fractal theory and its application to various aspects of industrial processes has been demonstrated. The application to environmental aerosols, especially those formed by combustion, has received much attention due to the increasing awareness of the global impact of aerosols on climate. Fractal analysis is a convenient framework for the description of complex morphologies and other dynamical parameters.
