ResMed is a world leader in the technology of developing products for treating obstructive sleep apnea (OSA). ResMed provided the first successful non-invasive treatment of OSA with their sleep apnea device. Noise reduction is an important issue in the development of this product, since these devices operate on a bedside table. This project will enable the acoustic performance of these small irregularly shaped mufflers to be reliably predicted and optimised. The successful outcomes will improve the quality of the well-being of the user. This research also has relevance to the design of mufflers for use in broader applications such as locomotives and ferries.Read moreRead less

Summary
High Rate Testing System for Materials and Structures. Human or natural disasters such as terrorist attack or tsunami take place and they have catastrophic consequences, in terms of fatalities and psyche of fear among the population, as well as enormous financial loss. 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 c ....High Rate Testing System for Materials and Structures. Human or natural disasters such as terrorist attack or tsunami take place and they have catastrophic consequences, in terms of fatalities and psyche of fear among the population, as well as enormous financial loss. 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

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. 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 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
