A novel approach to controlling boundary-layer separation. This project will involve fundamental research into the control of the fluid dynamical phenomena of boundary-layer separation and transition to turbulence. The project will be built upon a firm foundation of mathematical modelling of the complex behaviour of fluid flows that are near the onset of flow separation or turbulence. The project will produce results that will permit the development of control strategies that can be implemented ....A novel approach to controlling boundary-layer separation. This project will involve fundamental research into the control of the fluid dynamical phenomena of boundary-layer separation and transition to turbulence. The project will be built upon a firm foundation of mathematical modelling of the complex behaviour of fluid flows that are near the onset of flow separation or turbulence. The project will produce results that will permit the development of control strategies that can be implemented in a wide variety of important technological applications, such as drag reduction in the aerospace and ship industries as well as the control of stall (or loss of lift) in modern aircraft.Read moreRead less
Systematically model the large-scale complexity of turbulent floods and thin film flows. This project continues development of new models, and computer
simulation, of turbulent flood, river and estuarine flow. The models
will be based systematically upon established turbulence models to
resolve accurately the complex physical processes. The development of
new and robust computer models for thin layers of coating fluid will
aid many industrial processes. We also aim to provide correct ini ....Systematically model the large-scale complexity of turbulent floods and thin film flows. This project continues development of new models, and computer

will be based systematically upon established turbulence models to
resolve accurately the complex physical processes. The development of
new and robust computer models for thin layers of coating fluid will
aid many industrial processes. We also aim to provide correct initial
conditions and boundary conditions for simpler cases of the above
flows. The approach leads to a greater understanding of the range of
applicability of the models through better estimating the errors in the
modelling process. The project develops a fundamental enabling
methodology for engineering and the sciences.

The effect of diffusive mass transfer on interfacial fluid instabilities. A wide variety of industrial and physiological fluid flows fall into the general class of two-layer fluids wherein a fluid of one density/viscosity flows over another of a different density/viscosity. Such flows can ultimately become turbulent (that is, chaotic) through the growth of small background disturbances. An understanding of this process is important in controlling fluid dynamical mixing. This project will conside ....The effect of diffusive mass transfer on interfacial fluid instabilities. A wide variety of industrial and physiological fluid flows fall into the general class of two-layer fluids wherein a fluid of one density/viscosity flows over another of a different density/viscosity. Such flows can ultimately become turbulent (that is, chaotic) through the growth of small background disturbances. An understanding of this process is important in controlling fluid dynamical mixing. This project will consider two layer flows in the case when diffusive mass transfer acts at the fluid interface with the aim of determining how diffusion affects the process of transition-to-turbulence.Read moreRead less
Aerodynamic enhancement of the capture of fine particle emissions and gaseous pollutants by sorbents. Fine particulate emissions alone, and just within Australia's four largest cities, are estimated to be responsible for some 1600 deaths annually, and are a leading cause of asthma and other lung disease. Hence the economic and social benefits of greatly reducing fine particulate emissions is enormous. Similar benefits can be expected to arise from the enhanced capture of SOx, NOx and heavy metal ....Aerodynamic enhancement of the capture of fine particle emissions and gaseous pollutants by sorbents. Fine particulate emissions alone, and just within Australia's four largest cities, are estimated to be responsible for some 1600 deaths annually, and are a leading cause of asthma and other lung disease. Hence the economic and social benefits of greatly reducing fine particulate emissions is enormous. Similar benefits can be expected to arise from the enhanced capture of SOx, NOx and heavy metals. Many of these pollutants also contribute to the greenhouse effect, so the international exploitation of the technology will also help to mitigate climate change. Should suitable sorbents be developed for CO2 capture, the technology will also enhance carbon capture and storage.Read moreRead less
Assessment and Optimisation of Mixing and Aerodynamic Characteristics of Multi-Fuel Burners for Rotary Kilns. Cement kilns are increasingly being used to dispose of waste and low-grade biomass fuels. Being nominally greenhouse neutral, these fuels reduce greenhouse gas emissions by displacing fossil fuels. However, their use also presents significant technical challenges, one of which will be addressed by the proposed program. In building capacity of local industry to utilise these fuels in ceme ....Assessment and Optimisation of Mixing and Aerodynamic Characteristics of Multi-Fuel Burners for Rotary Kilns. Cement kilns are increasingly being used to dispose of waste and low-grade biomass fuels. Being nominally greenhouse neutral, these fuels reduce greenhouse gas emissions by displacing fossil fuels. However, their use also presents significant technical challenges, one of which will be addressed by the proposed program. In building capacity of local industry to utilise these fuels in cement kilns, it will open the door to other opportunities in the future. It will also increase the export earnings of an Australian company who will commercialise these outcomes internationally.Read moreRead less

A thermally stratified sea ice wave interaction facility: Predictions of climate change now impact all levels of society as future political, social and environmental plans are made on the basis of these models. Predictions require models of many complex dynamical processes with a wide range of parameters. An important process is the Marginal Ice Zone (MIZ) dynamics. The MIZ is the region between the open ocean and the fully ice-covered ocean where waves and ice interact, causing ice-breaking and wave attenuation. This unique facility will enable experiments in sea-ice-wave interactions in a controlled environment. Water and air temperature, thermal stratification, water waveform and ice properties will be adjusted in order to preserve key characteristics of the complex ocean environment.Read moreRead less
