Cement kilns are increasingly being used to dispose of waste and low-grade biomass fuels. Being nominally greenhouse neutral, these fuels reduce greenhouse gas emissions by displacing fossil fuels. However, their use also presents significant technical challenges, one of which will be addressed by the proposed program. In building capacity of local industry to utilise these fuels in cement kilns, it will open the door to other opportunities in the future. It will also increase the export earnings of an Australian company who will commercialise these outcomes internationally.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.

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
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.

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.

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.
