The community will benefit from the project by reduced air pollution and improved health and safety. Soot is a major air pollutant, adversely effecting public health, while also contributing directly to global warming. It also dominates heat transfer and influences the emissions of NOx and CO2. The project will significantly advance detailed understanding and modelling capability of flames containing soot. Hence it will provide significantly improved capability to optimise these flames in applications spanning gas turbines, power generation, minerals processing and fires.Read moreRead less
Detailed understanding of the behaviour of soot in, and emission from, turbulent flames and fires. While combustion processes involving soot have been widely employed for many years, their great complexity puts them beyond present capacity to understand or model reliably. Within a flame, soot plays an important role in radiant heat transfer, and hence in energy efficiency. Beyond a flame, soot can either be emitted as an unwanted air pollutant or as a desirable source of nano-particles, dependin ....Detailed understanding of the behaviour of soot in, and emission from, turbulent flames and fires. While combustion processes involving soot have been widely employed for many years, their great complexity puts them beyond present capacity to understand or model reliably. Within a flame, soot plays an important role in radiant heat transfer, and hence in energy efficiency. Beyond a flame, soot can either be emitted as an unwanted air pollutant or as a desirable source of nano-particles, depending on the application. The benefits to society from improved understanding and predictive capability include reduced air pollution, improved health and safety, increased efficiency in the utilisation of both fossil and alternative fuels, the support of the rapidly growing sector employing carbon nano-particles and increased fire safety.

Investigation of Strategies to Improve the Efficiency of Industrial Radiators and Cooling Coils. Innovative strategies for improving in-service effectiveness of tube & plate-fin heat exchange 'coils' will be explored. Such coils are used throughout chemical process industries, diesel powered plant, vehicles and air-conditioning systems. Coil manufacture is a 'mature' industry, but design concepts have changed little since 1950.

Innovative strategies for improving in-service effectiveness of tube & plate-fin heat exchange 'coils' will be explored. Such coils are used throughout chemical process industries, diesel powered plant, vehicles and air-conditioning systems. Coil manufacture is a 'mature' industry, but design concepts have changed little since 1950. Fouling of diesel engine 'radiators' in dusty conditions and in marine environments is endemic. New design concepts evolved via Computational Fluid Dynamic analysis will be manufactured and tested in the unique heat and mass transfer wind tunnel on the University's Industry Liaison Campus. The major outcome will be a rugged design methodology with broad applicability.Read moreRead less
Study of hydrocarbon flames under heat and gas recirculation conditions. This project aims to study gaseous flames under heat and gas recirculation conditions.

This project aims to study gaseous flames under heat and gas recirculation conditions. This technology has been proven to reduce fuel consumption, improve thermal efficiency and substantially reduce nitric oxides emission. The effect of mixing, turbulence and temperature on the structure and stability of these flames will be investigated. The project combines experimental and computational research applied to a laboratory scale burner and a small scale furnace. The main objectives are to better understand the chemical pathways in low temperature hydrocarbon flames under heat and gas recirculation conditions and to understand the effect of mixing and turbulence on the flame structure and pollutants emission.Read moreRead less
Understanding and predicting submarine hydrofoil noise. Australia needs to develop a more sophisticated underwater flow-induced noise research and development capability if it is to achieve its ambitious naval plans set out under the Defence White Paper. This project will develop an experimentally validated model to predict submarine noise for the purposes of submarine design, operation and procurement.

This proposal seeks to establish a state-of-the-art laser diagnostics facility with unique capabilities for non-intrusive measurements in dilute multi-phase flows. Such heterogeneous flows which involve stationary surfaces, disperse suspended droplets or suspended particles are found in many applications including engines, furnaces, industrial and chemical processing and micro-combustion devices. This facility will give Australian researchers the unprecedented opportunity to perform measurements of flow, mixing, temperature and composition fields in the gas and liquid or solid phases simultaneously. The resulting data will advance current knowledge in these complex flows and lead to new and improved reactor designs.

New understanding of turbulent flames with soot and particulate fuels. This project will develop the new understanding and models required to optimise practical furnaces, boilers and combustion chambers, most of which involve soot and/or particulate fuels. This work will be performed with state-of-the-art measurement and modelling tools through a well-established partnership of international researchers.
Quantification of heat release, NOx emissions and soot from high temperature gaseous flames. The ongoing importance of Australia's minerals processing sector depends on advanced combustion technology to minimise the emission of NOx and other greenhouse gases.

The ongoing importance of Australia's minerals processing sector depends on advanced combustion technology to minimise the emission of NOx and other greenhouse gases. The heat release and NOx emissions from the high temperature flames used in such processes is known to depend strongly on the presence of soot. However their optimisation and design is limited by a lack of fundamental data under relevant conditions. To address this need, new measurements and analysis will be performed to quantify the complex relationship between turbulent mixing, soot formation, heat release and NOx emissions under high temperature conditions of both fundamental and practical significance.
