Process studies for photocatalytic rejuvenation of spent industrial Bayer liquor. A new low-energy photocatalytic process for the continuous treatment of spent liquor from the Bayer process for alumina production has been demonstrated. This new technology can process up to 1500 litres of industrial caustic effluent per day with a reduction in carbon dioxide release. The photo-treated refinery wastewater also provides water savings of 30 per cent.
Application of tuneable nanofluids in regenerative supercritical power generation. The proposed project combines the simplicity, flexibility, robustness and thermodynamic effectiveness of GRANEXTM cycle with the advances recently made in nanotechnology.

Conjugate natural convection boundary layers. Conjugate natural convection systems occur when a conducting vertical wall separates fluids at different temperatures (that is at a window separating the interior of a room from the outside or when a container of fluid is placed in a refrigerator). This project will provide accurate predictions of such flows together with scaling relations.

The project intends to develop tools to accurate predict fountain flows. Volcanic eruptions, building ventilation and brine discharge from desalination plants are all examples of turbulent fountains and negatively buoyant jets. The project aims to conduct an investigation into the turbulent structure of fountains and negatively buoyant jets using numerical simulation and laboratory experiments, and to assess the accuracy of the commonly used integral models and test the effect of the use of more accurate entrainment relations. This may have a range of applications – enabling better prediction of environmental impacts, reduction of the adverse effects of the discharge of pollutants, and reduction in energy consumption in building ventilation and other industrial applications.Read moreRead less
