This project aims to develop a particle-scale microprobe to capture the transient dynamics of particle behaviours for pneumatic conveying. Slug flow pneumatic transport of granular materials such as mineral particles and food grains is extremely popular across the processing industry. However, without the fundamental understanding of the conveying mechanism at the particulate level, pneumatic conveyors are over-designed and energy intensive. The project aims to enable accurate measurement of the motion, inertia and force information at the particle scale, so as to produce more accurate design protocols for such a conveying system. Improved pneumatic conveyors may have the potential to reduce the energy consumption in such systems by up to a factor of 10.Read moreRead less

Micromechanical analysis of size segregation and its prediction in granular free-surface flows. Industries often suffer from size segregation in the handling and processing of granular materials, leading to significant economic consequences. This project aims to develop a fundamental understanding of size segregation and prediction models, enabling industries to eliminate, minimise, or manage the effects to an acceptable level.

Particle-scale modelling of particle-fluid flows in gas and oil extraction. This project aims to develop a particle scale model to study the pipeline transport of petroleum fluids. It will use a combined theoretical and experimental program, involving state-of-the-art discrete element modelling and simulation techniques, to describe the complex particle-fluid flow and erosion of pipeline transport in gas and oil extraction, quantify the effects of key variables, and formulate strategies for optimum process control under different conditions. The research outcomes are expected to be useful for the process control of pipeline transport in Australia’s important petroleum and energy-related industries.Read moreRead less
Combined Ozonation-Flotation for the Treatment of Potable Water. Water Authorities are tightly regulated to guarantee removal of pollutants such as algal cells and toxins, cryptosporidium oocysts, and geosmin from drinking water. Processing options such as membrane filtration are effective but become very expensive when continuously operated to protect against occasional contamination events. This project aims to develop a fully-integrated process combining flotation and ozonation which can be ....Combined Ozonation-Flotation for the Treatment of Potable Water. Water Authorities are tightly regulated to guarantee removal of pollutants such as algal cells and toxins, cryptosporidium oocysts, and geosmin from drinking water. Processing options such as membrane filtration are effective but become very expensive when continuously operated to protect against occasional contamination events. This project aims to develop a fully-integrated process combining flotation and ozonation which can be operated continuously when required in a number of different modes to provide a barrier against a range of contamination events. The process utilises much of the existing water treatment infrastructure reducing capital and operating costs.Read moreRead less

Combined ozonation/biologically active carbon filtration provides effective contaminant removal while minimizing disinfection by-product formation. However, the cost of installation in conventional water treatment plants is very high. This project will investigate the beneficial influence of ozonation on the micro-flocculation of small particles, with the aim to optimising particle removal by sedimentation prior to filtration. To do this, requires a clear understanding of how dissolved ozone interacts with particle surfaces for different water chemistries. The ideal outcome would be to develop a robust water treatment system that required BAC filtration only and eliminated the need for a conventional sand filtration stage as well.Read moreRead less
