There is a widespread need throughout the Australian transport, defence and construction industries for high performance energy absorption devices. Data from the Australian Transport Safety Bureau show that in 2002 there were 1,715 people killed in 1,525 crashes in Australia. The proposed research will develop advanced techniques for improving crashworthiness of vehicles, roadside barriers and other energy absorption devices. This will lead to significant reductions in injury to people and damage to structures caused by impact; and thus substantial savings for the nation from the enormous costs associated with the fatalities, injuries and structural damages.

Prediction and control of fluid-structure interactions. Fluid-flows create a pressure that can deform the surface of a structure or cause it to vibrate; an extreme example is the fluttering of a flag. Flow-induced vibration of the external panels of vehicles causes damage, noise and can adversely affect performance. This project will develop a wholly new approach for the analysis of these interactions. The versatility and completeness of the approach permits a step-change in the design of panels ....Prediction and control of fluid-structure interactions. Fluid-flows create a pressure that can deform the surface of a structure or cause it to vibrate; an extreme example is the fluttering of a flag. Flow-induced vibration of the external panels of vehicles causes damage, noise and can adversely affect performance. This project will develop a wholly new approach for the analysis of these interactions. The versatility and completeness of the approach permits a step-change in the design of panels, reducing material and manufacturing costs without compromise to safety and performance - an immense benefit for the myriad engineered products or structures that feature flow over a deformable surface.

Taming turbulence: Hydrodynamic stability and flow-structure interaction using grid-free computation. Turbulence is characterized as seemingly disordered fluctuations that impede the progress of an object through a fluid by creating increased frictional or drag forces. Using a new type of fluid-flow simulation, this project will generate advanced understanding of turbulence in the flow over the surface of a vehicle, be it a ship, car, aircraft or within a pipe, with the technological objective o ....Taming turbulence: Hydrodynamic stability and flow-structure interaction using grid-free computation. Turbulence is characterized as seemingly disordered fluctuations that impede the progress of an object through a fluid by creating increased frictional or drag forces. Using a new type of fluid-flow simulation, this project will generate advanced understanding of turbulence in the flow over the surface of a vehicle, be it a ship, car, aircraft or within a pipe, with the technological objective of reducing drag by adhering a compliant skin to the surface. While the correct choice of compliance relies upon understanding very complex flow-structure dynamics, the resulting technology is simple, robust and has low capital and maintenance costs. Clearly, drag reduction reduces fuel costs and lower fuel consumption is environmentally beneficial. Read moreRead less

An experimental and theoretical programme of research to resolve major obstruction-to-flow problems in bins and stockpiles. Many of Australia's industries rely on the efficient storage and handling of bulk solids materials such as minerals, chemicals, food-stuffs, agricultural products and pharmeceuticals. Often the handling processes are inefficient to the extent of affecting the economics of the industry. Here we propose two projects addressing those inefficiences resulting from stable obstr ....An experimental and theoretical programme of research to resolve major obstruction-to-flow problems in bins and stockpiles. Many of Australia's industries rely on the efficient storage and handling of bulk solids materials such as minerals, chemicals, food-stuffs, agricultural products and pharmeceuticals. Often the handling processes are inefficient to the extent of affecting the economics of the industry. Here we propose two projects addressing those inefficiences resulting from stable obstructions, such as "rat-holes", and those experimental arising from the unusual flow characteristics of fine powders. The major objectives are to use experimental and advanced mathematical modelling techniques, to produce reliable design models which minimise the occurrence of stable obstructions and provide reliable methods for increasing fine powder flow rates.Read moreRead less
Mathematical modelling of two-phase industrial granular flows. In many industrial processes involving flowing granular materials, the effect of air pressure can be significant. Such examples include pneumatic conveying, lock hoppers and air-impact moulding. The effect of pressurised air on a granular material can either compact it, or can cause sudden large flows. To model such complex phenomena, the frictional effects between the air and the solid granules must be accurately incorporated into a ....Mathematical modelling of two-phase industrial granular flows.

The effect of pressurised air on a granular material can either compact it, or can cause sudden large flows. To model such complex phenomena, the frictional effects between the air and the solid granules must be accurately incorporated into a two-phase continuum mechanical model for granular materials. This proposal will develop advanced mathematical models and computational procedures to predict complex two-phase granular flows for industrial problems.Read moreRead less

Vehicle accident is another example. In Australia, 1636 people were killed in 1481 road crashes, in 2005 alone. There is a great demand for research into devising novel materials and structures for optimum performance under such circumstances. The proposed new high rate testing system will significantly advance research in this area. The facility will directly support a range of research projects in material and structural design in military and civil vehicles, aerospace industry and defence.Read moreRead less
