This project will provide knowledge for Australian industry to develop new energy efficient refrigerated display cabinets, putting Australia in the forefront of commercial refrigeration display cabinet technologies. This will have a significant impact on sustainability of our environment and will assist Australia to meet present and future international climate obligations by contributing to the reduction of greenhouse emissions. The Government has already introduced new MEPS levels, and are planning to increase these to more stringent levels in 2007. The development of the techniques proposed in this application will be essential for manufacturers if they are to economically meet these MEPS level requirements. Read moreRead less
Heat Transfer Enhancement Techniques for Air Conditioning and Refrigeration Equipment. The proposed Project will make significant contribution towards the both fundamental understanding of heat transfer enhancement using dimpled surfaces and the design of heat exchangers and, in particular to the application of dimpled surfaces in air conditioning and refrigeration industries.

The proposed Project will make significant contribution towards the both fundamental understanding of heat transfer enhancement using dimpled surfaces and the design of heat exchangers and, in particular to the application of dimpled surfaces in air conditioning and refrigeration industries. Unlike the previous CFD studies which have been made on the assumptions that the flow is steady and decoupled from the heat transfer calculations in this Project the fully coupled problem will be solved, in which unsteady flows are allowed to occur over a dimpled surfaces. As a result we will be able to more accurately determine the resultant effects on the pressure drop and heat transfer. Read moreRead less
Enhanced Waste Heat Recovery from Low-grade Heat Sources Using a Novel Supercritical Power Cycle. Compared with conventional technologies for waste heat recovery, GRANEX cycle offers higher thermal efficiencies, better economics and a greater degree of robustness. If deployed ascross the country to recover even 10% of the nation's waste heat, it would reduce greenhouse emissions by 9 mega tonne which is roughly 1.6% of the annual national emissions. That is equivalent to the yearly CO2 emissions ....Enhanced Waste Heat Recovery from Low-grade Heat Sources Using a Novel Supercritical Power Cycle. Compared with conventional technologies for waste heat recovery, GRANEX cycle offers higher thermal efficiencies, better economics and a greater degree of robustness. If deployed ascross the country to recover even 10% of the nation's waste heat, it would reduce greenhouse emissions by 9 mega tonne which is roughly 1.6% of the annual national emissions. That is equivalent to the yearly CO2 emissions from 648,000 houses or 2 million cars. The proposed research will place Australia within the forefront of the research and development activities in the field of waste heat recovery and will clearly contribute to the Federal Government’s effort in the National Research Priority 1, An Environmentally Sustainable Australia.Read moreRead less
Development of a fuel control system for small two-stroke engines. The two-stroke engine is well known not only for its mechanical simplicity and power-to-weight advantages, but also for its high hydrocarbon emission caused by fuel short-circuiting. Driven by new regulations, developing new technologies for small two-stroke engines to meet pollutant emission standards has become urgent.

The two-stroke engine is well known not only for its mechanical simplicity and power-to-weight advantages, but also for its high hydrocarbon emission caused by fuel short-circuiting. Driven by new regulations, developing new technologies for small two-stroke engines to meet pollutant emission standards has become urgent. This project aims to develop a fuel control system for reducing hydrocarbon and other emissions of a two-stroke engine designed and produced by Australia's leading lawnmower manufacturer. The knowledge and technology developed will be broadly applicable. By reducing engine pollutant emissions and improving fuel energy efficiency, this research addresses environmental and energy efficiency imperatives.Read moreRead less

This project aims to develop a library of novel and two-dimensional Ruddlesden−Popper phases layered perovskites with controlled architecture and tunable bandgaps for high-performance energy harvesting applications. The as-synthesized perovskites are highly crystalline and sandwiched with staggered organic and inorganic layers, which are compatible with layer-by-layer manner to build vertical heterostructure, satisfying the premise of a solar cell with both high power conversion efficiency and low-cost. Apart from springing out a series of high impact publications and patents, a few of these demonstrations have a great potential to be substituted for fossil fuels which will help address clean energy generation and environmental problems.

Through the proposed theoretical and experimental studies, new electro-magneto-mechanical phenomena of the MR materials under various vectorial magnetisations will be observed. Based on the in-depth understanding of the complex vectorial magneto-rheological mechanisms, an accurate coupled model will be developed for design and analysis of novel dampers. These outcomes will greatly enhance the design capacity of Australian industry in smart structures, i.e. using novel dampers to reduce harmful vibrations and protect people in vehicles, buildings, and bridges. This will help Australians to live in a safer and healthier environment, and could save billions of dollars per year nationwide for treatment, recovery, and insurance claims.Read moreRead less

Gears are widely used in industry and transport. This project aims to integrate the two main methods of gear condition monitoring, vibration and oil analysis, and perform model-based wear prediction with the tribology and dynamic models continually updated on the basis of measured wear debris and vibration. New signal processing tools should allow estimation of relatively weak friction forces, previously neglected, as an important prognostic tool. This would allow detailed root cause analysis and prediction of remaining useful life. Improvements in gear prognosis would have safety and economic benefits by eliminating unforeseen catastrophic failures and optimising maintenance schedules.Read moreRead less
