Compact heat exchangers are increasingly considered for duties in many industrial applications, involving phase change processes of boiling and condensation. In many cases such applications are completely new and no previous experience or information is available for constructive design of compact heat exchangers. This project aims to develop a commercially-viable design methodology that will be innovative and novel with in mind of robust and speedy computations of key design parameters of compact boiling heat exchangers through the artificial neural networks (ANN) model and maintaining the inherent accuracy associated with the solutions of the boiling flow and heat transfer processes from computational fluid dynamics (CFD) and validated using experimental data. It will provide a cutting edge to the Industry Partner to compete successfully on the local and global market fronts in designing and manufacturing compact boiling heat exchangers.Read moreRead less
Making better decisions about built assets: learning by doing. This research will assist the built environment professions and their clients to make better decisions about new developments through a novel 'learning by doing' approach.

Decisions w ....Making better decisions about built assets: learning by doing. This research will assist the built environment professions and their clients to make better decisions about new developments through a novel 'learning by doing' approach. Used successfully in other fields such as natural resource management, this idea will capitalise on the large number of asset investments undertaken to benchmark original stakeholder intentions and aspirations against the reality of current performance. Decisions will be re-evaluated in the context of contemporary economic, social and environmental criteria to enable existing multi-criteria models to deliver more sustainable outcomes that are also feasible and in the national interest, and consequently minimise the industry's current exposure to future climate change.Read moreRead less
Defining and developing a marine cadastre for Australia. Australia's ocean territories cover an area 1.5 times larger than the nation's land mass. Systems for the management and administration of land in a spatial context have been developed over many years but no such system exists for the nation's oceans. A marine cadastre aims at providing a comprehensive spatial data infrastructure and spatial analysis tools for the assessment, administration and management of rights, restrictions and respo ....Defining and developing a marine cadastre for Australia. Australia's ocean territories cover an area 1.5 times larger than the nation's land mass. Systems for the management and administration of land in a spatial context have been developed over many years but no such system exists for the nation's oceans. A marine cadastre aims at providing a comprehensive spatial data infrastructure and spatial analysis tools for the assessment, administration and management of rights, restrictions and responsibilities in the marine environment. The objective of this project is to investigate the issues and define the problems associated with the development of a marine cadastre, thereby providing the foundation for future research.Read moreRead less
Regulation of large artery stiffness by endothelium-derived mediators and effects on the arterial pressure waveform. Stiffening of arteries is an important cardiovascular risk factor and increases with age, high blood pressure, high cholesterol and diabetes. Cells that line the blood vessels (endothelial cells), become damaged and this reduces the available amount of a dilator substance, nitric oxide, and increases the activity of a constrictor substance, endothelin-1. We have shown that nitric ....Regulation of large artery stiffness by endothelium-derived mediators and effects on the arterial pressure waveform. Stiffening of arteries is an important cardiovascular risk factor and increases with age, high blood pressure, high cholesterol and diabetes. Cells that line the blood vessels (endothelial cells), become damaged and this reduces the available amount of a dilator substance, nitric oxide, and increases the activity of a constrictor substance, endothelin-1. We have shown that nitric oxide regulates large artery stiffness and we believe that other endothelial mediators are also important regulators. Therefore, we aim to explore this in a series of studies. Regulation of stiffness of large arteries will improve treatment of age-related cardiovascular disease (eg isolated systolic hypertension)Read moreRead less
Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of g ....Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of generating air bubbles, to gain fundamental understanding of the foaming mechanism in currently used gassing techniques, and to invent ways to stabilise large bubbles within the emulsion. The project will provide scientific underpinning for the development of a new range of emulsion explosives manufactured by Orica for Australian and international markets, maintaining the Orica's position as a leader in the field of emulsion explosives.Read moreRead less
High Strength Steel Protection Bollards. Terrorist attacks cost Australians much human grief and millions of dollars. Prevention of an attack is paramount. Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards.

Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards. However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads. The investigators will apply their extensive knowledge in thin-walled tubular structures to establish the most economical means of designing high strength bollards. This knowledge will be transferred into design standards and Australia's limited defence resources.Read moreRead less

Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and ch ....Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and chemical interactions that occur between the particle and the oil-water interface, and develop a more efficient explosive that can be produced continuously on a commercial scale.Read moreRead less
