DROP DEFORMATION IN CONFINED MICROFLUIDIC GEOMETRIES. Increasingly, high technology applications in biotechnology and microtechnology industries need to process complex (non-Newtonian) fluids with dispersed particles/droplets in channels as small as several microns (microfluidics). A computational fluid dynamic model of non-Newtonian droplet deformation in microfluidic geometries will be developed, and validated using experimental measurements of the flow field in this project. The aim is to und ....DROP DEFORMATION IN CONFINED MICROFLUIDIC GEOMETRIES. Increasingly, high technology applications in biotechnology and microtechnology industries need to process complex (non-Newtonian) fluids with dispersed particles/droplets in channels as small as several microns (microfluidics). A computational fluid dynamic model of non-Newtonian droplet deformation in microfluidic geometries will be developed, and validated using experimental measurements of the flow field in this project. The aim is to understand and quantify factors influencing droplet deformation. Coupling non-Newtonian characteristics with microfluidic geometries will allow the continuous manufacture of micro-particles of specified size and shape for existing and new applications, and will provide guidance for further extending the process to nano-particle manufacture.Read moreRead less
The Evolution of Gas in Galaxy Groups. The evolution of gas in galaxy groups is poorly understood, but is crucial to understanding galaxy evolution. This project provides a training opportunity for a talented postdoc to conduct the first `multiwavelength census' of southern galaxy groups, perform simulations and make predictions of group properties at early times. We will better understand the evolutionary processes in groups and provide a `local anchor' for future surveys. The knowledge gained ....The Evolution of Gas in Galaxy Groups. The evolution of gas in galaxy groups is poorly understood, but is crucial to understanding galaxy evolution. This project provides a training opportunity for a talented postdoc to conduct the first `multiwavelength census' of southern galaxy groups, perform simulations and make predictions of group properties at early times. We will better understand the evolutionary processes in groups and provide a `local anchor' for future surveys. The knowledge gained will feed directly into the design of the future Square Kilometre Array, and raise Australia's profile in this $1B project. We exploit Australia's best astronomical facilities, and establish a new University-CSIRO collaboration.

Star Formation at Millimetre Wavelengths with the CSIRO Australia Telescope. The newly-upgraded CSIRO Australia Telescope Compact Array, together with the CSIRO Mopra Telescope, provide a unique and powerful combination for studying the millimetre-wave emission from molecules and cold dust in star formation regions. We propose to combine the astrophysical expertise of UNSW with the instrumental expertise of CSIRO to use these instruments to study the processes of star formation. There are two pa ....Star Formation at Millimetre Wavelengths with the CSIRO Australia Telescope. The newly-upgraded CSIRO Australia Telescope Compact Array, together with the CSIRO Mopra Telescope, provide a unique and powerful combination for studying the millimetre-wave emission from molecules and cold dust in star formation regions. We propose to combine the astrophysical expertise of UNSW with the instrumental expertise of CSIRO to use these instruments to study the processes of star formation. There are two parallel themes to this research: to commission and develop optimal techniques for using the new instruments, and to make use of them to explore the poorly-understood processes that cause stars to form.Read moreRead less
Photonic Crystal Signal Processing and Antenna Technologies. The information society in which we live requires increasingly high bandwidth, low cost communications. This project addresses two critically important technologies needed to meet these demands: signal processing devices and antennas. These devices will be designed using three-dimensional photonic crystals, which provide excellent possibilities for low-cost, highly integrated photonic circuits.

The information society in which we live requires increasingly high bandwidth, low cost communications. This project addresses two critically important technologies needed to meet these demands: signal processing devices and antennas. These devices will be designed using three-dimensional photonic crystals, which provide excellent possibilities for low-cost, highly integrated photonic circuits. Working prototypes will be built at microwave frequencies, but due to the scalability of electromagnetic theory these results are also valid in the optical domain. The outcomes of this project will be accurate theoretical models and empirical tests for new technologies that satisfy the future needs of the information society.Read moreRead less
Atomisation and Combustion Physics of Australian Bio-oils. Australia is highly dependent on fossil fuels for energy production and transport, and this dependence is growing. Wide spread substitution of liquid hydrocarbon fuels by indigenous renewable bio-oil has the potential to improve Australian's energy outlook and assist in reaching greenhouse gas targets. Understanding the interrelationships between the physical and chemical properties of bio-oil, its atomisation, droplet formation and com ....Atomisation and Combustion Physics of Australian Bio-oils. Australia is highly dependent on fossil fuels for energy production and transport, and this dependence is growing. Wide spread substitution of liquid hydrocarbon fuels by indigenous renewable bio-oil has the potential to improve Australian's energy outlook and assist in reaching greenhouse gas targets. Understanding the interrelationships between the physical and chemical properties of bio-oil, its atomisation, droplet formation and combustion physics is fundamental to the delivery of an efficient and reliable combustion process using this fuel. Measurements using laser based diagnostics of the atomisation flow, droplet formation and combustion process will provide the experimental data to understand this complex interrelationship.Read moreRead less
