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

Engine manufacturers are therefore undertaking substantial research and development in order to meet future legal requirements. One technology with proven emissions performance is gasoline direct injection (GDI).
This project requests funding for the detailed study of a GDI development engine. Sophisticated, laser based diagnostics and an ?optical access? engine will be used to examine the fuel spray, fluid motion and pollutant formation inside the cylinder during operation. Numerical simulations will complement these experiments. Using these results, the mechanisms of pollutant formation in a GDI engine will be determined.

Our goal here is to acquire fundamental knowledge about the redox behaviour of metal oxide oxygen carriers which, arguably, underpins the feasibility of the Chemical Looping Combustion (CLC) concept. Although the proposed work is fundamental and will contribute to the advancement of knowledge, the results will have immediate practical applications in power generation industry at both national and international levels. This should significantly contribute to the Australian Government's efforts in producing world class solutions for abatement of greenhouse emissions (Research Priority 1: An Environmentally Sustainable Australia, Priority Goal 1.4 - Reducing and capturing emissions in transport and energy generation).Read moreRead less

Gravity obscures some of the most subtle phenomena that are key to answering outstanding questions today, including combustion phenomena. The main scientific benefit from this fundamental research stems from the fact that it addresses far-reaching issues that transcend the boundaries of combustion science. It provides a rare opportunity to observe and understand the fundamental phenomena of combustion beyond the limitation of gravity on the earth surface, thus enriching our body of knowledge in this area. This new knowledge will provide a foundation for tomorrow's combustion science and technology.Read moreRead less
Physics of combustion of multicomponent alternative transport fuels. Reducing Australian reliance on imported fuels, especially oil, will enhance the Australian long term energy outlook and the national energy security, and will assist Australia to reach future greenhouse gas emission targets. At a local level, the production of alternative transport fuels has the potential to provide rural Australia with a sustainable biomass-based industry. The establishment of fast growing wood plantations ....Physics of combustion of multicomponent alternative transport fuels. Reducing Australian reliance on imported fuels, especially oil, will enhance the Australian long term energy outlook and the national energy security, and will assist Australia to reach future greenhouse gas emission targets. At a local level, the production of alternative transport fuels has the potential to provide rural Australia with a sustainable biomass-based industry. The establishment of fast growing wood plantations to supply the needs of the new industry can assist regions of low rain-fall and high salinity to recover. Exporting advanced Australian alternative fuels technology to other countries with similar energy and environmental problems will further enhance the economic and social benefit to Australia.Read moreRead less
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

This project employs a unique combination of experimental measurements and fundamental quantum chemical calculations to study the oxides which form on the surface of carbon as it burns. Our objective is to develop a quantitative model for the kinetics of carbon combustion which will be a profound improvement over existing approaches. Such a model would provide the basis for the improved prediction of carbon combustion and gasification in current (coal-burning) power generation appliances, as well as catering for new approaches to lowering greenhouse emissions which also depend on the combustion and gasification of carbon as coal, biomass or refuse-derived fuel.Read moreRead less

Achieving targets for greenhouse gas reduction will require practical, easily implemented alternative fuels for vehicles. Converting existing truck/bus diesel engines to dual-fuel systems using natural gas is important. In particular, for long distance application, these systems need to allow flexible switching from sole diesel to dual-fuel operation and good gas substitution at low loads within cities. An earlier ARC funded project allowed UNSW to develop the world's most compact, flexible HEUI diesel injector. This project aims to develop, test and explore dual-fuel combustion using a compact single unit, combined NG/HEUI injector which will have considerable combustion and operational advantages.Read moreRead less
