Experimental and numerical studies of the packing and piling of coal. This project is oriented to the coal and steel industries, which are important to Australia. In fact, the coal industry creates a significant employment and produces 80% of electricity in Australia. Australia is also the world's biggest coal exporter. This project will develop methods to control the packing and piling processes of coal, which are of fundamental importance to many granular processes. The benefits from the proje ....Experimental and numerical studies of the packing and piling of coal. This project is oriented to the coal and steel industries, which are important to Australia. In fact, the coal industry creates a significant employment and produces 80% of electricity in Australia. Australia is also the world's biggest coal exporter. This project will develop methods to control the packing and piling processes of coal, which are of fundamental importance to many granular processes. The benefits from the project include improvements in productivity, coke quality and fuel efficiency, which will lead reduced energy consumption and pollution emission and thereby improve the competitiveness of Australia's coal and steel industries.

Fundamental studies of screening processes in coal preparation. Screening is a most important unit operation widely used in industries but not well understood. This project will investigate the fundamentals governing the dynamic behaviour of coal slurry on desliming screens by a combined theoretical and experimental program. Its aim is to develop and validate a computer model that can simulate the operation under various conditions at a particle level, providing a cost effective way to quantify ....Fundamental studies of screening processes in coal preparation. Screening is a most important unit operation widely used in industries but not well understood. This project will investigate the fundamentals governing the dynamic behaviour of coal slurry on desliming screens by a combined theoretical and experimental program. Its aim is to develop and validate a computer model that can simulate the operation under various conditions at a particle level, providing a cost effective way to quantify the screening performance in relation to materials, machine and operation conditions. It will generate a basis for developing better design and control strategies of screen operation, resulting in an improved competitiveness of Australia's mineral industry.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.

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
Model studies of the flow and thermal behaviour of non-spherical particles in fluid bed reactors. The Australian steel industry has a turnover of around $11 billion (5% of total manufacturing), being a largest manufacturing sector in Australia. Iron ore sintering and blast furnace ironmaking are two important processes in an integrated steel works. This project aims to understand and model the particle-fluid flow and thermal behaviour of non-spherical particles in the two processes, formulating ....Model studies of the flow and thermal behaviour of non-spherical particles in fluid bed reactors. The Australian steel industry has a turnover of around $11 billion (5% of total manufacturing), being a largest manufacturing sector in Australia. Iron ore sintering and blast furnace ironmaking are two important processes in an integrated steel works. This project aims to understand and model the particle-fluid flow and thermal behaviour of non-spherical particles in the two processes, formulating strategies for improving the process control and productivity and energy saving. The research outcomes (theory/model/understanding) are useful to fluid bed reactors which are widely used in mineral/metallurgical/chemical industries. Their application can improve the competitiveness of the steel and other industries in Australia.Read moreRead less
