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.

This project aims to protect distribution networks by reducing harmonics and electromagnetic Interference generated by modern power electronics equipment. Due to global demand for energy savings and reductions in greenhouse gas emissions, the utilisation of renewable energy sources and efficient loads using power electronics technology in distribution networks is increasing. Aspects of this technology are highly complex and not well understood and the robustness of existing and future power grids will be affected. The project will minimise risk factors associated with high frequency noise and resonances in low voltage grids both of which are very important for power electronics manufacturers and utility companies in Australia.Read moreRead less
Entrainment and Mixing in Turbulent Negatively Buoyant Jets and Fountains. 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 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
Towards energy-efficient lighting based on light-emitting diodes: the role of silicon carbide grown on Si Wafers. This project will investigate a potential solution to the problems of cost and quality of light-emitting diodes for solid-state lighting. The expected outcome is knowledge to underpin future development of solid-state lighting that is suitable for a wide replacement of the much less efficient and effective incandescent bulbs and fluorescent tubes.

Rational design of light-emitting materials for lighting and displays. This project aims to solve the most pressing problem in organic light emitting diodes - the lack of highly efficient, phosphorescent blue emitters. The project expects to generate new understanding of energy loss mechanisms in such devices from multiscale quantum mechanical models, which describe the interaction of the emitter with its environment, and to design new materials via big data approaches.

The project expects to generate new understanding of energy loss mechanisms in such devices from multiscale quantum mechanical models, which describe the interaction of the emitter with its environment, and to design new materials via big data approaches. Expected outcomes include a fundamental understanding of non-radiative decay processes in organometallic complexes and more efficient lighting and display technologies. This project should provide significant benefits in reducing energy use, as lighting and displays consume around a quarter of the energy generated in developed countries.Read moreRead less
Reactivity of Carbon-Carbon Composites. This project investigates the reactivity of pitch-coke carbon composites with the aim of minimising oxidative carbon loss from anodes during aluminium smelting. Such carbon loss accounts for about 15 percent of the total carbon consumption in smelting, and its reduction will provide considerable economic benefit besides contributing to mitigation of greenhouse gas emission.

Such carbon loss accounts for about 15 percent of the total carbon consumption in smelting, and its reduction will provide considerable economic benefit besides contributing to mitigation of greenhouse gas emission. In the present project the effect of coke calcination and composite baking temperatures on the relationship between anode microstructure and reactivity in oxygen as well as carbon dioxide will be investigated, and optimum process conditions determined for minimum reactive carbon loss during smelting.Read moreRead less

Iron flow batteries are one of the most promising choices for clean, reliable and cost effective long-duration energy storage. The main obstacle for large scale commercial deployment is the low round-trip energy efficiency caused by the competitive side reaction that occurs at the negative electrode during battery charging. The project aims to address this issue by engineering the negative electrode-electrolyte interface with functional materials to improve battery performance and thus further reduce the cost of energy storage. Expected outcomes include new materials and methods for advanced battery technology and manufacturing. The success of the project will significantly support the national priority of net-zero carbon emissions by 2050.Read moreRead less

Understanding rock failure is of vital interest to researchers and practitioners across a wide range of productive activities, including those of critical importance to the Australian economy such as mining and civil engineering design and contracting. The failure of rocks is a complex function of interactions between pre-existing micro-cracks and loading conditions. This project will develop a much-needed understanding of the mechanisms leading to rock failure and damage. The project will explore micro and macro-scale mechanisms under both static and cyclic loading conditions. Laboratory testing and micro-analysis will be combined with discrete element modelling to achieve this end.Read moreRead less
