The long term motivation of the project is to reduce the considerable energy consumption of aeration in wastewater treatment. The research develops numerical computational fluid dynamics (CFD) models to provide detailed understanding of the performance of Wessex Water's aeration systems. It studies the factors that affect the hydrodynamics, dissolved oxygen (DO) and aeration performance in an oxidation ditch. The flow pattern and dissolved oxygen distribution are evaluated tangibly by comparison between computation and on-site measurement. CFD simulations are used to evaluate aeration system design. The novelty of the research are the distributions of Biochemical Oxygen Demand (BOD) and bubble size.

I am considering working in either academic research or in industry. My general interests are computational fluid dynamics (CFD) modelling of engineering, computer animation fluid simulation and 3D graphical visualisation. My project interests are fluid dynamics in water and wastewater treatment, environmental hydraulics (water pollution, flooding, water distribution networks), building physics, sports science fluid dynamics (swimming, cycling, athletics, winter sports), fluid simulation of visual effects in films and games, 3D graphical visualisation of fluids and 3D graphical visualisation of large scale engineering infrastructure design.
