At a fundamental research level, Australia's active participation in this area of national priority and research strength will be advanced through our published research, which will increase our understanding of wind turbine wakes and their effects in wind farms. This understanding will then be used to produce improved methods of predicting wind turbine performance. Such methods are needed by wind energy designers to produce better wind farms. It will also be used to recommend how to improve the aerodynamic design of turbine components, such as the blades and hub. Numerical tools will be developed for industry use, and training will be provided to personnel, thereby increasing the capabilities of Australia's growing wind energy industry.Read moreRead less
Investigation into flow over complex topography and escarpments for wind turbine siting using experimental and computational methods. This project will improve national capability to optimise power production from wind turbine farms in complex terrain by improving the understanding of the flow regime. By better understanding separated regions and the turbulent structures within these regions power production can be optimised and fatigue risks associated with turbine positioning in complex sites ....Investigation into flow over complex topography and escarpments for wind turbine siting using experimental and computational methods. This project will improve national capability to optimise power production from wind turbine farms in complex terrain by improving the understanding of the flow regime. By better understanding separated regions and the turbulent structures within these regions power production can be optimised and fatigue risks associated with turbine positioning in complex sites can be reduced. This will improve confidence in wind farm site assessment techniques and consequently reduce economic risks associated with current wind farm viability assessments. By increasing national capacity to generate clean energy stationary energy emissions can be reduced. This project will also deliver high calibre graduates that will be potential future industry leaders.Read moreRead less

We will attack industrially-important problems in fluid mechanics by building new, and substantially enhancing existing, international collaborations between key complementary teams of internationally-recognised French and Australian researchers. Funding will support the exchange of 6 senior staff and 3 graduate students, which, in turn, will measurably benefit the research output of a further 20 graduate students and 7 post-doctoral fellows associated with closely-related projects. From the Australian perspective, the planned exchanges will bring new research expertise, knowledge and skills, which will be focussed on a diverse range of applications. Target industries (with existing collaborations) include Airbus and Dassault Aviation in Europe, and Aerosonde and Warman pumps in Australia. Read moreRead less
Response of Metallic Foam Core Sandwich Panels under Impact and Blast Loadings. Human or natural disasters such as vehicle crashes, terrorist attacks or tsunami take place with catastrophic consequences, including significant loss of life and considerable financial losses. For example, in Australia in 2002 over 1,700 people died as a result of vehicle crashes. Research on new materials composites and novel composite structures for use in vehicles, buildings and other man-made structures will be ....Response of Metallic Foam Core Sandwich Panels under Impact and Blast Loadings. Human or natural disasters such as vehicle crashes, terrorist attacks or tsunami take place with catastrophic consequences, including significant loss of life and considerable financial losses. For example, in Australia in 2002 over 1,700 people died as a result of vehicle crashes. Research on new materials composites and novel composite structures for use in vehicles, buildings and other man-made structures will be undertaken to evaluate their performance under extreme or disastrous conditions. This project will investigate the performance of sandwich panels with a cellular core structure under high impact or blast loading conditions. The findings will be directly applicable to structural design of military and civil vehicles and components for the aerospace industry in order to mitigate the level of impact or blast loading under extreme conditions.Read moreRead less

Cold gas-dynamic spray has the potential to revitalize and revolutionize the Australian manufacturing sector and economy. It is a technologically advanced flexible free-forming process with potential applications in the aviation, automotive, naval and bio-medical sectors. It allows for the design of functional surfaces from the nano-scale to the macro-scale that can be manufactured by spraying material coatings of arbitrary thickness and density on a substrate. The process of the spray particle delivery is crucial and not understood. This research will investigate the fluid physics and spray particle physics to gain the essential understanding necessary to make this process energy efficient and extend its range of application.Read moreRead less

The experimental information that can be gained from this infrastructure would lead to significant advances in understanding turbulent flows, which would impact a broad range of engineering and geophysical fields. Some specific examples include the development of efficient turbulence control strategies for the reduction of skin-friction drag and improved combustion processes, resulting in not only better fuel efficiency for vehicles but also reduced CO2 and pollutant emissions. Significant advances could also be made in the area of understanding the dispersion of particles, including pollutants, in the atmosphere; wind turbine design and implementation strategies, and climate change modelling.Read moreRead less

This project aims to predict the performance and scalability of viscous transfer turbines. The work will be carried out with Micromachines Ltd., a firm developing working turbines with 50 mm rotors. The goal of the research is to gain an understanding of the scaling laws for these turbines, in order to predict their performance. Viscous transfer turbines have a very simple disc construction making them ideal for manufacturing as small-scale units (with a 5 mm rotor). Small enough to replace batteries, but with a higher power output, they would provide the need for higher power output devices to replace batteries.Read moreRead less
