A particle can be defined as a discrete object or quantity of matter that is
separated from the surrounding environment by an interface. Suspension of solid or
liquid particles in a gas is referred to as an aerosol particle or simply an aerosol.
Dust, smoke, mists, fog, haze, and smog are various forms of common
aerosols/particles.
We use laser imaging techniques — PIV, LDA, and PDPA — combined with high-speed
filming to obtain detailed images of fluid–particle systems. For example, high-speed
filming was used to capture spray atomisation and measure averaged droplet diameters.
We have also introduced a new visualisation technique to look at wake flows from
moving objects. These results are used as the basis for further detailed analysis
using CFD techniques.
