This project aims to research the unsteady aerodynamic wakes of cars, trucks, athletes, turbines and micro-air vehicles. Researchers will use the flow measurement system for large-scale industrial aerodynamics to resolve high speed and large scale industrial flows. The system’s primary objective will be the characterisation of complex, three-dimensional turbulent flows. It is anticipated that the research will lead to reduced aerodynamic drag in transport and improve wind power generation, ultimately reducing emissions and improving efficiency and national competitiveness in sport. The advanced system will strengthen Australia’s position as an advanced engineering design hub.Read moreRead less

Delivering a better understanding of unsteady wakes has real potential to further our future capabilities of reducing bluff body parasitic drag. The national benefit derived from this project is the advancement of knowledge of a complex fluid mechanics problem, with secondary benefits arising from the specific and practical application to sports aerodynamics. By better understanding the wake structure and its interaction with a locally oscillating bluff body this knowledge can feed into the field of active flow control in the transport sector. The potential for emissions mitigation by lowering aerodynamic losses in the ground transportation section through active aerodynamic control is significant.Read moreRead less
WAKE FLOWS WITH UPSTREAM TURBULENCE IN MARINE, ATMOSPHERIC AND BUILT ENVIRONMENTS. Through improved understanding of turbulent wakes the project will have applications across aeronautics and hydrodynamics, leading to more efficient engineering designs to reduce flow drag. In marine environments our findings will improve coastal ocean models and the prediction of pollutant dispersal, nutrient fluxes and sediment transport, and contribute to the management of biological productivity (NRP 1.5).

In marine environments our findings will improve coastal ocean models and the prediction of pollutant dispersal, nutrient fluxes and sediment transport, and contribute to the management of biological productivity (NRP 1.5). In the atmospheric boundary layer, the results will assist planners to improve wind environments near large buildings or clusters of buildings, benefiting the safety of aircraft at takeoff and landing. The project will develop collaboration and help maintain the strength of Australian research in environmental flows.Read moreRead less
Atomisation and Combustion Physics of Australian Bio-oils. Australia is highly dependent on fossil fuels for energy production and transport, and this dependence is growing. Wide spread substitution of liquid hydrocarbon fuels by indigenous renewable bio-oil has the potential to improve Australian's energy outlook and assist in reaching greenhouse gas targets. Understanding the interrelationships between the physical and chemical properties of bio-oil, its atomisation, droplet formation and com ....Atomisation and Combustion Physics of Australian Bio-oils. Australia is highly dependent on fossil fuels for energy production and transport, and this dependence is growing. Wide spread substitution of liquid hydrocarbon fuels by indigenous renewable bio-oil has the potential to improve Australian's energy outlook and assist in reaching greenhouse gas targets. Understanding the interrelationships between the physical and chemical properties of bio-oil, its atomisation, droplet formation and combustion physics is fundamental to the delivery of an efficient and reliable combustion process using this fuel. Measurements using laser based diagnostics of the atomisation flow, droplet formation and combustion process will provide the experimental data to understand this complex interrelationship.Read moreRead less
Enabling low greenhouse gas emissions from road vehicles through the proper use of alternative fuels. A major increase in alternative transport fuel use appears necessary in our response to the challenges of climate change and energy security. This proposal will advance our fundamental understanding of key aspects of the combustion of particular alternative fuels, thus enabling proper engine design and so maximising greenhouse and energy security benefits. Further, the Australian automotive indu ....Enabling low greenhouse gas emissions from road vehicles through the proper use of alternative fuels. A major increase in alternative transport fuel use appears necessary in our response to the challenges of climate change and energy security. This proposal will advance our fundamental understanding of key aspects of the combustion of particular alternative fuels, thus enabling proper engine design and so maximising greenhouse and energy security benefits. Further, the Australian automotive industry is a major employer and exporter, and needs to develop and/or maintain international leadership in low emission technologies to ensure its long term viability. This proposal builds a consortium of local organisations with common interests, thus helping local industry respond to several, significant challenges that they presently face.Read moreRead less
Airports of the Future. This project will enhance the capabilities of Australian airport operators to design and manage complex airport systems.

This project will enhance the capabilities of Australian airport operators to design and manage complex airport systems. Research outcomes will enable the identification of patterns of behaviour and will provide tools to manage airport effectiveness and balance conflicting security, economic and passenger-driven pressures. Outcomes will improve productivity, enhance capabilities for critical infrastructure protection, and lessen the cost of mandated security, estimated to grow to $152M by 2010 for the five major Australian airports. The deliverables of this project will be transferable to other complex socio-technical systems providing the potential to transform a range of Australian critical infrastructure and transportation hubs.Read moreRead less
Environmentally sustainable shipping through improved understanding and management of wall-bounded turbulence. The thin region of turbulent flow that is pulled along by a ship's hull as it moves through the water accounts for up to 90 per cent of the overall resistance and a large amount of the fuel burnt. This project aims to control or tame recurrent flow patterns within these turbulent regions to reduce resistance, overall fuel cost and emissions from shipping.
Precision inertial sensing with cold atoms. Many advances in our technology-driven society rely on precision measurement. The project will provide the Australian industrial and government sectors with new and better inertial sensors to measure acceleration, rotation and gravity. The technology will find application in navigation, defence, mineral exploration, earth science and fundamental physics.
Aerodynamic interaction of bluff bodies with applications to sports aerodynamics. Numerical modelling and experiments will be combined by this project to characterise the flow and reduce drag on a set of objects in the wake of another object. The Olympic pursuit cycling team is a typical application, with small improvements leading to major competitiveness gains. Findings will also apply to Paralympic team sports, and potentially transportation.
Towards an event based model of combustion generated sound. This proposal will develop new tools for predicting combustion generated sound. Since combustion noise often limits system performance, these new tools could be used to significantly reduce emissions of greenhouse gases and other pollutants from power generation and transportation.
