Summary
Resolving flame stabilisation mechanisms in the transition to moderate or intense low oxygen dilution (MILD) combustion. Next-generation combustion technologies are required in the transition to more efficient, and less polluting, energy production. This project will address the important issue of understanding flame stabilisation on a fundamental level to facilitate the design and development of more efficient and sustainable combustion systems.

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

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.

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
