Management of water resources and water distribution networks is important as Australia and the world face increasing water shortages. A significant aspect of water management is prevention of supply losses in urban and non-urban water distribution networks - a vital factor in improving water security of Australian cities and agricultural production regions. This research will develop ultrasonic flow-velocity technology, which can be retrofitted to existing water distribution networks, providing distributed high precision water flow measurement systems that can prevent the loss each year of more than 155GL of water through leaks and burst in Australia's capital cities alone.Read moreRead less

Dynamic input adjustment to improve the stability of transient swirling flows in spray dryers. This project will use leading-edge numerical techniques to advance the science of flow stabilisation using dynamic flow modulation techniques. Improved sustainable processing will be enabled using this flow modulation in spray dryers to reduce processing problems due to the depositon of particles on dryer walls.

Engineering suspended particle sprays through controlled cavitation. This project aims to use cavitation to engineer particle size in sprays of micronised particles suspended in a propellant, and develop a physical mechanism for this process. Understanding how cavitation affects the size of agglomerates in the liquid phase and droplet size in a spray is critical to developing spray devices that require precise control over the final particle size. This will be achieved through high-resolution op ....Engineering suspended particle sprays through controlled cavitation. This project aims to use cavitation to engineer particle size in sprays of micronised particles suspended in a propellant, and develop a physical mechanism for this process. Understanding how cavitation affects the size of agglomerates in the liquid phase and droplet size in a spray is critical to developing spray devices that require precise control over the final particle size. This will be achieved through high-resolution optical imaging techniques and synchrotron X-ray diagnostics. This project is expected to provide physical insight with applications for inhaled and topical pharmaceutical sprays, and industry spray drying of food products.Read moreRead less

Novel modelling of fluid-structure interactions in biological flows. The objective of this project is to develop a novel method to model fluid-structure interactions and turbulence in cardiovascular systems. The cardiovascular system is essential in providing nutrient and waste transport throughout the body.

The objective of this project is to develop a novel method to model fluid-structure interactions and turbulence in cardiovascular systems. The cardiovascular system is essential in providing nutrient and waste transport throughout the body. Because blood vessels and red blood cells are flexible, they are subjected to large deformations with significant effects on physiological functions such as blood distribution and oxygen release. Fluid-structure interactions are critical for understanding the intricacies of such systems but it is still a challenge to model these systems realistically using numerical methods. Expected outcomes of the project include better simulations of three-dimensional fluid-structure interactions and improved understanding of the behaviours of biological systems.Read moreRead less

Oil,litter and sediment are serious pollutants in stormwater which go hand in hand with human and industrial activity. An outcome of this research will be to develop a device capable of removing such gross pollutants from stormwater at higher efficiencies than that currently commercially available. Vital wetland resources such as Moreton Bay near Brisbane, a wetland of international significance that contributes around $400 million to the local economy,are under threat from polluted stormwater. Similar problems are occuring right around the entire coast of Australia and also in some inland waterways.Read moreRead less
