Discrete particle modelling and analysis of complex particle-fluid flows. Multiphase processes are widely used in both conventional and modern industries in Australia and worldwide, however rarely reach more than 60% of design capacity because of a poor understanding of their fundamental characteristics. This project aims to overcome this problem using an extensive combined fundamental and applied approach. The resulting theories, computer models and simulation techniques will be applied to imp ....Discrete particle modelling and analysis of complex particle-fluid flows. Multiphase processes are widely used in both conventional and modern industries in Australia and worldwide, however rarely reach more than 60% of design capacity because of a poor understanding of their fundamental characteristics. This project aims to overcome this problem using an extensive combined fundamental and applied approach. The resulting theories, computer models and simulation techniques will be applied to improve process design, control and optimisation. Consequentially, productivity and Australian competitiveness will be significantly enhanced in its most important industries such as minerals, metallurgical, chemical, energy, and materials.Read moreRead less
Flow field evaluation of AusIron top submerged injection system. The top submerged gas injection system is widely used in the metallurgical industry in many metal refining processes. The AusIron process, which uses dual top submerged lances injection, has been developed recently for direct smelting of iron ore to produce pig iron using low quality coal as fuel and reductant. Successful implementation of the process requires optimum furnace design. This project aims to study fluid flow within the ....Flow field evaluation of AusIron top submerged injection system.

The AusIron process, which uses dual top submerged lances injection, has been developed recently for direct smelting of iron ore to produce pig iron using low quality coal as fuel and reductant. Successful implementation of the process requires optimum furnace design. This project aims to study fluid flow within the furnace using a laboratory scale model, plant trials and numerical analysis. The project will enhance our fundamental understanding of the top submerged injection processes and assist in optimising AusIron furnace design.Read moreRead less
Multiscale modelling of the transport phenomena of liquid iron and slag in ironmaking blast furnace. Blast furnace ironmaking is a key operation in the steel industry which, with an annual turnover around $11 billion, is a significant manufacturing sector in Australia. This project, focused on the behaviour of liquid iron and slag, can generate computer models that can reliably describe the complicated multiphase flow and thermochemical processes in the furnace. The implementation of the resulta ....Multiscale modelling of the transport phenomena of liquid iron and slag in ironmaking blast furnace. Blast furnace ironmaking is a key operation in the steel industry which, with an annual turnover around $11 billion, is a significant manufacturing sector in Australia. This project, focused on the behaviour of liquid iron and slag, can generate computer models that can reliably describe the complicated multiphase flow and thermochemical processes in the furnace. The implementation of the resultant models and the new understanding should lead to long life campaigns, better operational control, decreased fuel consumption, improved productivity and reduced environmental impact. This, together with the proposed research training, is important to the development of Australia's competitive steel industry.Read moreRead less
