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
Development of a low emission, pulverised fuel rotary kiln burner utilising a low pressure-drop, oscillating jet nozzle. A low pressure-drop oscillating jet nozzle, developed recently by the investigators, will be applied to pulverised fuel combustion to provide an advanced, low emission burner for the cement industry. This design is expected to overcome the high pressure drop of the present design which limits its range of application. The program will apply advanced measurement techniques to ....Development of a low emission, pulverised fuel rotary kiln burner utilising a low pressure-drop, oscillating jet nozzle. A low pressure-drop oscillating jet nozzle, developed recently by the investigators, will be applied to pulverised fuel combustion to provide an advanced, low emission burner for the cement industry. This design is expected to overcome the high pressure drop of the present design which limits its range of application. The program will apply advanced measurement techniques to study the aerodynamic behaviour of particles, which control many aspects of the combustion. These will be used to advance understanding and for the development and validation of computational fluid dynamics (CFD) models. A preferred design will be assessed in FCT's model lab and then in full-scale trials.Read moreRead less
Quantification of heat release, NOx emissions and soot from high temperature gaseous flames. The ongoing importance of Australia's minerals processing sector depends on advanced combustion technology to minimise the emission of NOx and other greenhouse gases. The heat release and NOx emissions from the high temperature flames used in such processes is known to depend strongly on the presence of soot. However their optimisation and design is limited by a lack of fundamental data under relevant c ....Quantification of heat release, NOx emissions and soot from high temperature gaseous flames. The ongoing importance of Australia's minerals processing sector depends on advanced combustion technology to minimise the emission of NOx and other greenhouse gases. The heat release and NOx emissions from the high temperature flames used in such processes is known to depend strongly on the presence of soot. However their optimisation and design is limited by a lack of fundamental data under relevant conditions. To address this need, new measurements and analysis will be performed to quantify the complex relationship between turbulent mixing, soot formation, heat release and NOx emissions under high temperature conditions of both fundamental and practical significance.

Development of deformation-failure-mechanism based parameters for design of microstructured optical fibre and photonics assembly. Australia has exceptional quality and depth in photon science research, with a demonstrated capacity to found and grow commercial ventures. However, the optimal design of interconnections in a photonic package is severely restricted by a lack of detailed knowledge of their deformation and failure mechanisms. The proposed study will use novel techniques to create a bas ....Development of deformation-failure-mechanism based parameters for design of microstructured optical fibre and photonics assembly. Australia has exceptional quality and depth in photon science research, with a demonstrated capacity to found and grow commercial ventures. However, the optimal design of interconnections in a photonic package is severely restricted by a lack of detailed knowledge of their deformation and failure mechanisms. The proposed study will use novel techniques to create a basis for mechanism-based deformation and failure models that will then be used to improve the design and lifetime of new type microstructured optical fibres and adhesive assemblies, expanding and enhancing Australia's capacity in the areas.

Summary
State of Art Particle Size Analysers. Particulate materials are encountered in many different forms, sizes and environments, and vastly different areas such as biological, environmental, chemical and materials engineering. Particle size and its distribution are fundamental properties of these materials. Existing particle size measuring equipment in Australia is poor as currently available facilities cannot accurately resolve particle sizes in concentrated dispersions, nor can they visualise the ....State of Art Particle Size Analysers. Particulate materials are encountered in many different forms, sizes and environments, and vastly different areas such as biological, environmental, chemical and materials engineering. Particle size and its distribution are fundamental properties of these materials. Existing particle size measuring equipment in Australia is poor as currently available facilities cannot accurately resolve particle sizes in concentrated dispersions, nor can they visualise the in situ structure and size of fragile assemblies of particles (flocs). This proposal seeks funding for a suite of complementary particle size analysers, for use in an extensive number of research areas, to specifically address these critical current deficits.Read moreRead less
