Surface roughness and its effects on wall-bounded turbulence. Examples in engineering where turbulence is important are: wind tunnel model testing, numerical prediction of turbulent skin friction drag over an aircraft wing, turbulent forces and acoustic field around a submarine or a road vehicle, and the dispersion of pollutants in the atmosphere. Turbulence may also be beneficial, for example, in improving engine combustion and decreasing pollutant emissions.

Examples in engineering where turbulence is important are: wind tunnel model testing, numerical prediction of turbulent skin friction drag over an aircraft wing, turbulent forces and acoustic field around a submarine or a road vehicle, and the dispersion of pollutants in the atmosphere. Turbulence may also be beneficial, for example, in improving engine combustion and decreasing pollutant emissions. Hence this study will have national benefits in many scientific fields, for example, in fuel savings (economy and energy ), stability of road vehicles (safety and health), noise generation and acoustic signatures of submarines (transforming defence technology and safeguarding Australia).Read moreRead less
Wall Turbulence Drag: Physical Mechanisms and Practicable Control Strategies. The proposed research will build on Australia's well-established strengths in Fluid Mechanics, and aim to establish within Australia world-leading expertise in turbulence control and drag reduction technology. This will have direct benefits to the Australian economy through Tourism (among other industries) by reducing the adverse impact of rising fuel prices on long-distance air travel, on which Australia is disproport ....Wall Turbulence Drag: Physical Mechanisms and Practicable Control Strategies. The proposed research will build on Australia's well-established strengths in Fluid Mechanics, and aim to establish within Australia world-leading expertise in turbulence control and drag reduction technology. This will have direct benefits to the Australian economy through Tourism (among other industries) by reducing the adverse impact of rising fuel prices on long-distance air travel, on which Australia is disproportionately reliant due to its geographic isolation. Efficient turbulence control strategies will also lead to improved combustion processes, resulting in not only better fuel efficiency but also reduced CO2 and pollutant emissions.Read moreRead less

Control systems theory provides principles and methods for design of complex engineering systems that automatically maintain desired performance despite changes in their environment (e.g. autopilot in an aircraft). This field is facing many new exciting challenges at the dawn of new millenium, such as design of complex engineering systems in possibly networked, asynchronous and distributed environments. The network will play a major role in addressing these challenges by providing a national research focus, facilitating collaboration and the sharing of people and ideas. By delivering a National Graduate School, the network will enhance learning conditions for graduate students. Moreover, it will provide an important catalyst between Australian universities and industry. This initiative will be essential in assessing the present state of control research in Australia and drafting a detailed plan for the network's leading research role in the future.

Development of an active noise control system for sleeper seats on large commercial aircraft. Possible avenues will be investigated to actively reduce aircraft cabin noise experienced by passengers in sleeper seats, using localised active noise control (ANC). Previous work has focused on headsets and upright seat headrests which represent a different problem to the partially enclosed sleeper seats considered here.

Possible avenues will be investigated to actively reduce aircraft cabin noise experienced by passengers in sleeper seats, using localised active noise control (ANC). Previous work has focused on headsets and upright seat headrests which represent a different problem to the partially enclosed sleeper seats considered here. Efficiency and robustness problems that affect existing ANC systems will be addressed. A prototype system will be produced for a business class sleeper seat in a wide body aircraft. A second outcome is the establishment of a robust integrated system design procedure that can be used to quickly develop ANC systems for future designs.Read moreRead less
Anomalous isotope effects in atmospheric ozone and carbon dioxide. The anomalous isotopic composition of atmospheric ozone, which has been a puzzle for over twenty years, will be investigated by laboratory and atmospheric measurements. An understanding of the source of this anomaly and its effect on the isotopic composition of other trace atmospheric gases, especially CO2, would provide unique opportunities for constraining the tropospheric and stratospheric ozone budgets and determining the his ....Anomalous isotope effects in atmospheric ozone and carbon dioxide. The anomalous isotopic composition of atmospheric ozone, which has been a puzzle for over twenty years, will be investigated by laboratory and atmospheric measurements. An understanding of the source of this anomaly and its effect on the isotopic composition of other trace atmospheric gases, especially CO2, would provide unique opportunities for constraining the tropospheric and stratospheric ozone budgets and determining the history of a particular air mass. The method of detection will be high resolution FTIR spectroscopy which, in contrast to traditional mass-spectrometric methods, provides information about the position of the heavy atom in an enriched ozone molecule and requires no sample preparation.Read moreRead less
