The creation of new and advanced materials and composites will underpin the growth in many industrial and economic activities in Australia. This project will meet the substantial scientific and technological challenges in exploring and finding optimal microstructures for materials and composites with desired functional properties. The proposed research will significantly extend a topological optimization technique known as ESO/BESO - an Australian initiative that has earned a widespread international recognition. Its further development and applications will enable the Australian researchers and engineers to maintain and enhance the national capacity to exploit a niche market in the design of novel materials and composites.Read moreRead less
Viscous extensional flow and drop breakoff. Honey falling from a spoon is an everyday example of a viscous fluid in a free extensional flow which may eventually break up into drops. Such flows are important in modern technologies including ink-jet printing, welding, soldering and molten metal processing, polymer and glass fibre spinning, and for rheological measurement. We seek to increase understanding of the mechanisms governing such flows, particularly the role of initial conditions and the ....Viscous extensional flow and drop breakoff. Honey falling from a spoon is an everyday example of a viscous fluid in a free extensional flow which may eventually break up into drops. Such flows are important in modern technologies including ink-jet printing, welding, soldering and molten metal processing, polymer and glass fibre spinning, and for rheological measurement. We seek to increase understanding of the mechanisms governing such flows, particularly the role of initial conditions and the geometry of the original containing vessel, together with balances between forces such as inertia, gravity, viscosity, viscoelasticity, and surface tension, through a theoretical, computational and experimental study of the fluid mechanics.Read moreRead less

This project aims to characterise probabilistically the severe convective wind storm risk (thunderstorm and tornado) to Australia under current and future climates. This will be achieved using a new coupled analysis-simulation based approach to wind hazard analysis. It will also characterise the complex wind structure within these wind storms by integrating three-dimensional data from novel high-resolution observation networks into a unifying wind field model. The project aims to generate the requisite information that allows convective wind storms to be explicitly accounted for in national and international wind-resistant design standards, thus acting to mitigate the devastating impacts of future events.Read moreRead less
Versatile dosimetry systems for radiotherapy and industrial applications: novel storage phosphor and associated reader technologies. Radiotherapy is an important procedure in the treatment of cancer, and it is essential that the radiation dosage can be accurately measured. This project will develop technology which will enable us to monitor radiation dosage in real time and very accurately. This will be of importance in medical science and also for industrial applications.

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
Energy dissipation and vibration-assisted self-healing in structures with topological interlocking. High dissipation of impact and vibration energy, vibration-assisted self-healing, high tolerance to block failure and an ease of assembly/disassembly make topological interlocking structures ideal for safety barriers, protective shields and floating structures.

High dissipation of impact and vibration energy, vibration-assisted self-healing, high tolerance to block failure and an ease of assembly/disassembly make topological interlocking structures ideal for safety barriers, protective shields and floating structures. The theory of these phenomena will open a way for more efficient protection of infrastructure against both natural and human perpetrated impacts and for developing new methodology in constructing mobile marine bases. This constitutes the main benefit of the project. Furthermore, understanding the resonance structure of travelling waves will improve methods of non-destructive monitoring by back analysing spectral signatures of the waves.Read moreRead less

Current approval methods for determining fire properties of construction materials are often incorrect in yielding properties that can be used in situations removed from test conditions. The main aim of this project is to obtain fundamental fire properties by examining the ignition and extinction processes of diffusion flames near solid surfaces. The project undertakes detailed study of flame spread in the direction opposite to the flow of air, which defines the initial fire growth and is important in fire propagation. Results from this project will provide scientific underpinning for the development of approval standards for new materials, which are needed to support Australia's transition from prescriptive to performance based building codes.Read moreRead less
