The key items of infrastructure in our cities are seen to be in crisis. Yet despite a growing willingness to fund new infrastructure, governments at all levels struggle to devise, rank and deliver infrastructure projects. The project will recover and rebuild a language for understanding the role of infrastructure in Australian cities and then devise criteria for better enactment of the infrastructure procurement and provisioning processes. The project's prime outcomes will intersect with a growing need for better ways to build and operate large economic infrastructure and thus contribute to building cities that perform better economically, are more liveable, and contribute to long term environmental sustainability goals.Read moreRead less
A high performance, robust and sensorless Natural Field Oriented controller for induction machine drives. Natural Field Orientation (NFO) is a technique of field oriented control of AC machines that is potentially very robust, able to operate at low speeds, and inherently sensorless. However, it is a little known fact that under regenerative conditions the algorithm is unstable. The primary aim of this project is to develop a NFO algorithm that is stable under regeneration, and has minimum depen ....A high performance, robust and sensorless Natural Field Oriented controller for induction machine drives. Natural Field Orientation (NFO) is a technique of field oriented control of AC machines that is potentially very robust, able to operate at low speeds, and inherently sensorless. However, it is a little known fact that under regenerative conditions the algorithm is unstable. The primary aim of this project is to develop a NFO algorithm that is stable under regeneration, and has minimum dependence on machine parameters. If these aims are achieved the NFO algorithm would be a significant addition to control algorithms for AC machines, allowing their use in a broader range of applications.

Traditional two level converters have significant problems in high voltage applications - high output dv/dt damages insulation and motor bearings, and the semiconductor switches have high switching losses.
Multilevel converters hold the promise of alleviating these problems. This project will research and develop multilevel converter technology for static VAR compensators and medium voltage drives, initially targeted at mining applications.Read moreRead less

This new heat exchanger overcomes the practical implementation problems of previous latent energy heat exchangers such as heat-wheels. The main application of this innovative heat exchanger will be to improve the capacity and efficiency of air conditioning systems. As the new heat exchanger is very compact it will be ideally suited for integration with air conditioning coils. Existing latent heat wheels are very bulky and are difficult to integrate into standard air conditioner installations.Read moreRead less
Stability, transition and heat transfer in thermally coupled natural convection boundary layers. Thermally coupled natural convection systems occur when a conducting vertical wall separates two fluids at different temperatures. Such configurations occur, for example, at a window separating the interior of a room from the outside or when a container of fluid is placed in a refrigerator. Improved building heating/cooling and ventilation, and more efficient refrigeration systems, require a thoroug ....Stability, transition and heat transfer in thermally coupled natural convection boundary layers. Thermally coupled natural convection systems occur when a conducting vertical wall separates two fluids at different temperatures. Such configurations occur, for example, at a window separating the interior of a room from the outside or when a container of fluid is placed in a refrigerator. Improved building heating/cooling and ventilation, and more efficient refrigeration systems, require a thorough understanding and predictive capability for these flows. This project will develop experimental, numerical and analytic tools to predict these flows and provide simple scaling relations for bulk flow parameters such as the heat transfer across the wall, which will be of immediate use in the associated industries.Read moreRead less

The project aims to develop computational models to predict emissions of nitric oxides and carbon monoxide from sugar-mill boilers burning bagasse. Bagasse combustion does not contribute to greenhouse gas emissions and clean and efficient combustion of this fuel has become very important for the sugar industry and for Australia. The project combines the opportunity of direct boiler measurements by SRI with the modelling expertise at the University to develop combustion-kinetics models for these species. The models will be incorporated into the previously developed computational fluid dynamics - combustion code of the furnace to give the capability of emission prediction as a function of burner operating conditions and fuel parameters.Read moreRead less

The aim of this project is to increase the heat transfer from heated vertical surfaces to an ambient fluid by stimulating an early transition to turbulence. Such passive heat transfer occurs in heat transfer devices, natural ventilation systems and in many environmental settings. Enhanced heat transfer will greatly improve the performance of these systems. The project will provide the length scales, frequency and amplification rate for the occurence of the secondary spanwise mode that is the primary mechanism for turbulent transition. This will provide guidance for the development of appropriate roughness elements and heating length and time scales.Read moreRead less
Cue Acquisition as a Mediator of Cognitive Skills Development. As the Australian workforce ages and there is a consequent reduction in the availability of experienced practitioners, organisations are going to be faced with the dilemma of placing relatively inexperienced staff in positions that were once occupied by experts. The result is a potential increase in the risks to critical infrastructure, such as electricity transmission. In this project, we expect to develop a set of principles that c ....Cue Acquisition as a Mediator of Cognitive Skills Development. As the Australian workforce ages and there is a consequent reduction in the availability of experienced practitioners, organisations are going to be faced with the dilemma of placing relatively inexperienced staff in positions that were once occupied by experts. The result is a potential increase in the risks to critical infrastructure, such as electricity transmission. In this project, we expect to develop a set of principles that can ensure that scenario based training is targeted to those aspects of the situation that are most important in maintaining the integrity of the system. The outcome is not only a safer system, but one that provides a structured approach to the acquisition of skills amongst employees.Read moreRead less
