Multi-disciplinary research and applications of CFD focusing on three main projects - Inhalation Project; Indoor and Built Environment; Fluid-Particle Dynamics. My research also extends to topics linked with Industry Partners, and International Collaborations. Projects range from wood dust particle exposure to diesel particle deposition in reactors.

Investigating respiratory function from the environment into the upper respiratory airway including the nasal cavity, pharynx, larynx, and tracheobronchial airway. The inhaled air may also contain airborne particles which we account for. We seek to understand the behaviour of biological fluids such as mucus, and physiological functions such as olfaction, inhalation, and clearance of foreign particles in the airway.
Investigating indoor air and particle flow behaviour for improving energy efficiency, and thermal comfort in building designs and; inhalation exposure to contaminants. The ventilated air is typically accompanied by buoyancy forces due to temperature differences in the room. Any occupants inside a room introduces additional heat flux, while contaminants in the enclosed environment become prone to re-dispersion from any occupant movement.
We use laser imaging techniques such as 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 a spray atomization to capture the averaged droplet diameters. We have also introduced a new visualisation technique to look at wake flows from moving objects. These results are used as basis for further detailed analysis using CFD techniques
