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.
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 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 ....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 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.
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. In the present project the effect of coke calcination and composite baking temper ....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. 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
Design tools for optimising data centre layout to minimise energy usage. Data centres are major consumers of energy worldwide, mainly through the need to cool the equipment. It has become imperative to develop the science for reducing this consumption. Rising computing demand, increasing power density, and increasing infrastructure and energy costs are major issue for data centres around the world. Our research will provide a powerful alternative to conventional thermal management techniques for ....Design tools for optimising data centre layout to minimise energy usage. Data centres are major consumers of energy worldwide, mainly through the need to cool the equipment. It has become imperative to develop the science for reducing this consumption. Rising computing demand, increasing power density, and increasing infrastructure and energy costs are major issue for data centres around the world. Our research will provide a powerful alternative to conventional thermal management techniques for cooling high-density heat loads in mixed-density environments. We will address the key issue of energy minimisation through a detailed flow analyses by the use of numerical simulations and optimisation algorithms.Read moreRead less

Summary
Micro-mechanical and micro-structural aspects of strength variation in rocks under various loading conditions. 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 d ....Micro-mechanical and micro-structural aspects of strength variation in rocks under various loading conditions. 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

A large percentage of the old train systems in Australia have old equipment which decreases the efficiency and reliability of the system and they can be replaced by high power smart converters with minimum losses and electromagnetic interference. This project aims to improve the efficiency of train systems by intelligent distributed control systems which reduces fuel consumption and greenhouse gas emissions. The outcomes can be applied to other transport systems in Australia. Another benefit is the production of a PhD graduand with significant experience in the use of smart power converters to improve efficiency of all types of transport systems. Read moreRead less

The socio-economic benefits to Australia from the project include (i) a novel holistic modelling tool to building design that maximises indoor comfort and provides acceptable air quality for the inhabitants whilst minimising energy usage in transit oriented urban developments; and (ii) estimation of energy consumption for different building designs and operation with respect to air quality and thermal comfort. The ultimate economic benefit of this research will be a reduction in health care costs and lost productivity as well as reduction of energy used and associated emissions. The research will also place Australia in the forefront of international progress and the race towards better methods for achieving environmental sustainability.Read moreRead less
Insulated sandwich panels in high temperature environments. A robust model comprising pyrolysis of polymeric material coupled with gas combustion will be developed to predict the burning behaviour of expanded polystyrene insulated sandwich panels. These models will provide an effective design tool for fire safety engineering design and the assessment of a wide range of polymeric materials in fire conditions.
