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.

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
Plasma-Catalytist Hybrid Process for Simultaneous Removal of NOx and SOx. Coal combustion provides over 80% of the electricity produced in Australia, with the power stations being major emitters of the pollutants NOx and SOx. This project will potentially lead to a new technology to simultaneously remove NOx and SOx in a single and economical process, eliminating the secondary waste streams that disadvantage current competing technologies. This will provide: significant environmental benefits f ....Plasma-Catalytist Hybrid Process for Simultaneous Removal of NOx and SOx. Coal combustion provides over 80% of the electricity produced in Australia, with the power stations being major emitters of the pollutants NOx and SOx. This project will potentially lead to a new technology to simultaneously remove NOx and SOx in a single and economical process, eliminating the secondary waste streams that disadvantage current competing technologies. This will provide: significant environmental benefits for Australia in reducing these dangerous atmospheric pollutants; economic advantage to our power stations by enabling cheaper, more efficient technologies and consolidate Australia's leading position in the world in air pollution control.

Homogeneous Combustion Catalysts for Efficiency Improvements and Emission Reduction in Diesel Engines. Australia currently consumes about 25 billion litres of diesel annually through the mining industry, road transportation and electricity generation for remote communities which presentins a significant cost and carbon footprint. A small reduction of say 2.5% in diesel consumption nationwide by improving engine performance and energy efficiency can result in more than $0.5 billion in savings and ....Homogeneous Combustion Catalysts for Efficiency Improvements and Emission Reduction in Diesel Engines. Australia currently consumes about 25 billion litres of diesel annually through the mining industry, road transportation and electricity generation for remote communities which presentins a significant cost and carbon footprint. A small reduction of say 2.5% in diesel consumption nationwide by improving engine performance and energy efficiency can result in more than $0.5 billion in savings and a reduction of 1.75 million tonnes in greenhouse gas emission annually. The homogeneous combustion catalysts, to be developed in this research for direct doping into diesel supply system, will help realise these objectives and contribute to the development of an environmentally sustainable Australia.Read moreRead less

It will strengthen ties between UNSW and UMN and provide opportunities for further collaboration.Read moreRead less
Modelling of Slug Pneumatic Conveying with an In-situ Microprobe Sensor. This project aims to develop a particle-scale microprobe to capture the transient dynamics of particle behaviours for pneumatic conveying. Slug flow pneumatic transport of granular materials such as mineral particles and food grains is extremely popular across the processing industry.

This project aims to develop a particle-scale microprobe to capture the transient dynamics of particle behaviours for pneumatic conveying. Slug flow pneumatic transport of granular materials such as mineral particles and food grains is extremely popular across the processing industry. However, without the fundamental understanding of the conveying mechanism at the particulate level, pneumatic conveyors are over-designed and energy intensive. The project aims to enable accurate measurement of the motion, inertia and force information at the particle scale, so as to produce more accurate design protocols for such a conveying system. Improved pneumatic conveyors may have the potential to reduce the energy consumption in such systems by up to a factor of 10.Read moreRead less

Increasing the operational lifetime and optimising the design of crankcase oil-mist filters. Australia is one of the largest (per capita) users worldwide of heavy diesel engines, within sectors such as transport, mining, construction, shipping and power generation (usage of many of the above is concentrated in regional communities e.g. mining).

Australia is one of the largest (per capita) users worldwide of heavy diesel engines, within sectors such as transport, mining, construction, shipping and power generation (usage of many of the above is concentrated in regional communities e.g. mining). This work will minimise emissions from such industries, as well as reduce lubricant oil usage - thereby maximising waste oil recovery and reuse (approx 5500 tonnes p.a.). Oil mists can be regarded as volatile organic compounds (VOCs) for the purposes of CO2 equivalent emissions, so therefore, the efficient capture of oil mists will reduce carbon emissions from the above industries in Australia.Read moreRead less
Micromechanical analysis of size segregation and its prediction in granular free-surface flows. Industries often suffer from size segregation in the handling and processing of granular materials, leading to significant economic consequences. This project aims to develop a fundamental understanding of size segregation and prediction models, enabling industries to eliminate, minimise, or manage the effects to an acceptable level.
