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

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
A new role for vibration analysis in gear wear modelling and prediction. This project aims to improve prediction of the remaining useful life of gears. 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.

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

Research into techniques for enhancing the heat transfer performance of finned-tube heat exchangers. This project explores several methods for enhancing the heat transfer performance of mechanically bonded finned tube heat exchangers. The methods would be analysed experimentally, and using finite elements, numerically. Any increase in heat transfer efficiency would contribute to the conservation of energy, and therefore, of natural resources. An improved design of heat exchangers would give a de ....Research into techniques for enhancing the heat transfer performance of finned-tube heat exchangers. This project explores several methods for enhancing the heat transfer performance of mechanically bonded finned tube heat exchangers. The methods would be analysed experimentally, and using finite elements, numerically. Any increase in heat transfer efficiency would contribute to the conservation of energy, and therefore, of natural resources. An improved design of heat exchangers would give a definite competitive edge to the Australian manufacturer. An equally significant outcome would be the training of a research person in industry-related research and skilled both in experimental and numerical procedures.Read moreRead less
Modelling the Transient Effects in Dense Phase Gas-Solids Flow in Pipelines. Almost every physical item we use in our daily lives at some point requires the transport and handling of powdered or granular materials during the manufacturing process. Be it food (sugar, flour), chemicals (soap powders, detergents), cosmetics (talc, face powder) or electricity generation (coal and ash); each of these industries uses the flexibility of pipeline systems to transport powders and granular solids using ai ....Modelling the Transient Effects in Dense Phase Gas-Solids Flow in Pipelines. Almost every physical item we use in our daily lives at some point requires the transport and handling of powdered or granular materials during the manufacturing process. Be it food (sugar, flour), chemicals (soap powders, detergents), cosmetics (talc, face powder) or electricity generation (coal and ash); each of these industries uses the flexibility of pipeline systems to transport powders and granular solids using air as the motive force. However, the cost of poor design and the inaccurate prediction of system performance adversely affect the efficiency of many industries. Improvements to the accuracy of gas-solid flow modeling particularly for low velocity dense phase systems will have a direct impact on manufacturing efficiency.Read moreRead less
Performance of Centrifugal Chillers using Hydrocarbons. Centrifugal chillers cool most large buildings. Their energy consumption and fluorocarbon emissions are a global environmental concern. A 40% increase in rotational speed and replacement of the fluorocarbon refrigerant by a hydrocarbon is proposed. Over 4% energy savings with no performance changes is predicted. The aims are to prepare a conversion protocol, measure chiller performance before and after conversion, develop a new model of ....Performance of Centrifugal Chillers using Hydrocarbons. Centrifugal chillers cool most large buildings. Their energy consumption and fluorocarbon emissions are a global environmental concern. A 40% increase in rotational speed and replacement of the fluorocarbon refrigerant by a hydrocarbon is proposed. Over 4% energy savings with no performance changes is predicted. The aims are to prepare a conversion protocol, measure chiller performance before and after conversion, develop a new model of evaporator heat transfer and correlate the model with chiller measurements. The capital cost of compliance with the Montreal Protocol for a large building will be reduced by $10,000 with about $5,000 in annual energy cost savings.Read moreRead less

This project aims to develop a novel data-driven dynamic reliability assessment platform to improve predictive maintenance ability in complex cyberphysical systems (CPSs). This will be achieved by identifying which degradation mechanism(s) are likely to cause an impending failure, and then highlighting the event to trigger for maintenance service or control operation. The expected outcomes are new methods and tools needed to leverage failure prognostics and prognostics-informed maintenance/control for making CPSs resilient with reduced levels of redundancy. This research will produce major advancements in extending core components’ life and durability in complex CPSs, bringing economic benefit for Australia industry.Read moreRead less
