The long-term integrity of engineering assets depends on the quality of their maintenance which runs into billions of dollars per year in Australia. This project aims to develop a new fundamental automated technique for the detection and diagnosis of machinery faults. The innovation lies in the ability of this technique to not depend on knowledge of fault components in the discrete wavelet packet analysis. All other work conducted to date depends on knowledge of these components and their location. The results of this work will vastly improve the costly manually based diagnostics procedures in the maintenance of plant and industrial assets.Read moreRead less
Development of Canonical Mist Filter Models. Over one million tonnes of oil (mist) is wasted every year – and emitted to the atmosphere through inefficient filtration. Over 50 per cent of energy usage in most process industries is for filtration and separation processes, yet mist filters and separators are largely designed by trial and error, resulting in sub-optimal, inefficient designs. Recent advances by the research team have, only now, made it possible to develop accurate models for such sy ....Development of Canonical Mist Filter Models. Over one million tonnes of oil (mist) is wasted every year – and emitted to the atmosphere through inefficient filtration. Over 50 per cent of energy usage in most process industries is for filtration and separation processes, yet mist filters and separators are largely designed by trial and error, resulting in sub-optimal, inefficient designs. Recent advances by the research team have, only now, made it possible to develop accurate models for such systems. This work intends to be the first to develop accurate, broadly applicable models for all processes in mist filters, thereby providing immense process efficiency benefits, together with improved worker and environmental protection, and less wastage of dwindling oil resources.Read moreRead less

This project aims to create a research capacity for direct printing of femtolitre volumes of functional liquids onto devices and surfaces. This project expects to enable the development of new sensing and electronic devices that require a novel fabrication step with delicate materials that cannot be deposited using existing processes. Expected outcomes include new chemical and biological sensors created through collaborative research between the partner institutions and researchers. The benefits of this project should include the creation of a new rapid prototyping facility for Australian researchers, and the application of these capabilities for the development of new low-cost sensors for environmental gas sensing and glucose monitoring.Read moreRead less
The study of wear debris using advanced technologies. A large portion of the operating cost of machinery is associated with wear due to the interaction between moving surfaces, which generates wear particles as by-products. The wear particles thus carry information regarding the wearing process, and can be used to assess the machine's condition and further facilitate failure prediction and minimise maintenance. This project will explore the mechanisms and possible influence of corrosion on the w ....The study of wear debris using advanced technologies.

The wear particles thus carry information regarding the wearing process, and can be used to assess the machine's condition and further facilitate failure prediction and minimise maintenance. This project will explore the mechanisms and possible influence of corrosion on the wearing process. A new methodology will be developed to quantify the wearing process. This research will significantly advance our understanding with respect to wear and provide innovative means for identifying wear mechanisms/phases.Read moreRead less
Optimising gaseous and particulate emissions from diesel engines. About $3.7 billion is spent annually in Australia on respiratory diseases. Diesel vehicle emissions of nano- and ultra-fine urban air particulate pollution are a significant factor in this disease. This project will directly addresses this problem by developing a technology to monitor and reduce diesel particulate emissions.

This project aims to investigate and develop a novel air flow enhancement concept, induced plume swirl, and its engineering approaches to boost the cooling capacity of natural draft cooling towers (NDCTs). These towers are widely used in thermal power plants due to their low operating costs. The project will explore why and how the artificial natural convective air swirls (vortices) significantly increase the updraft inside NDCTs and identify effective, low-energy cost swirl inducement methods to increase the efficiency of operation. A wide application of this technology will result in economic and environmental benefits, including increases in overall energy conversion efficiencies, cuts in operational costs in the order of billions, and reductions in carbon emissions in the thermal power sector.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

Vibration and wear debris analyses are the two main condition monitoring techniques for machinery maintenance and fault diagnosis. However, they can diagnose less than 50% of faults. A series of experimental and theoretical studies on the correlation of the two techniques will be conducted. This project will integrate advanced technologies including 3D microscopy, neural networks and expert systems to develop an artificial intelligent system based on the dependent and independent roles of the two condition monitoring techniques. Successful outcomes will result in an improved maintenance program and reduction in human involvement, and will provide significant economic benefit to engineering industries.Read moreRead less

The proposed project promotes a conceptual advance in the application of plate waves for the quantitative reconstruction of laminar defects by investigating fundamental experimental and analytical aspects of a novel approach in plate wave ultrasonic tomography. A successful development will have a comparable significance in the area of health monitoring of thin structures as computer tomography had in medical imaging. Previous attempts have ignored wave scattering effects, and therefore do not describe the correct physics of the problem. With its combined experimental-numerical approach, the proposed fundamental studies will help to identify the potential of plate wave ultrasonic tomography for in-situ health monitoring of realistic structures and smart materials design.Read moreRead less
