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
Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. Thi ....Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. This information will be input to comminution and wear models to predict pulveriser performance and wear patterns. Simulation results will be validated using measurements from scale visualisation and working models.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
Production of a compact disk summarising the evolution and impact of Boger fluids. In 1977 the discovery of a unique class of materials, now called Boger fluids, was reported in the Journal of Non-Newtonian Fluid Mechanics. These materials have had a huge impact in the development of non-Newtonian fluid mechanics, to the extent that the Institute of Non-Newtonian Fluid Mechanics in the UK have offered to make a cd documenting the impact of these materials.

Large amounts of waste plastics go to landfill daily. Landfill simply buries our wastes for future generations and can contribute to the contamination of ground water. This project aims to develop an advanced pyrolysis technology to produce transport diesel from waste plastics. This technology is an economically attractive and environmentally friendly way for the disposal of waste plastics without any environmental problems associated with the landfill or direct incineration of waste plastics. As this technology is based on advances in Australian research and development, exporting this to other countries will further enhance its economic and social benefits to Australia.Read moreRead less

This project aims to develop Mineral Looping Plastic Reforming (MLPR), a chemical looping reforming process for tonnage production of carbon nanofibers from plastic waste. This efficient process uses naturally occurring minerals (limestone, dolomite and ilmenite) to convert plastic waste to carbon nanofibers. The project will research the inner working of the MLPR process and the reforming reactions of plastics in the presence of naturally occurring mineral mixtures. This project is expected to make Australia a leader in waste use, facilitate the uptake of abundant waste streams to produce high value products, and resolve sustainability, energy and environmental issues in Australia.Read moreRead less

Many chemical reactions occurring in solid materials during heating significantly affect the materials' stability, and subsequently affects the processes of production of clean energy, material synthesis, catalyst preparation, and nanotechnology. No equipment currently exists in Australia that will mitigate the wide range of conditions in such reactions in materials processing. This situation impedes research progress in Australia, disadvantages Australian research students, and ultimately makes our research less competitive internationally. The establishment of the proposed apparatus will increase the competitiveness of Australian science and engineering, and contribute to the development of new Australian technologies that are important to the Australian economy and to environmental sustainability.Read moreRead less
