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
Bio-oil from woody biomass - a sustainable fuel for Australia. At present many alternative energy supply systems suffer from factors like high costs, inefficiency and in some cases inappropriate application of immature technology and so are unsustainable. To overcome these problems, this research proposes the development of an integrated biomass solution to energy supply as well as dry land salinity. By doing so a sustainable and cost effective industry can be developed. Furthermore, if such an ....Bio-oil from woody biomass - a sustainable fuel for Australia.

To overcome these problems, this research proposes the development of an integrated biomass solution to energy supply as well as dry land salinity. By doing so a sustainable and cost effective industry can be developed. Furthermore, if such an industry is based on advances in Australian research and development, exporting this to other countries with similar problems, will further enhance its economic and social benefit to Australia.Read moreRead less

Summary
Integrated Combustion Research Facility for Biomass Derived Fuels. Bio-mass derived fuels are gaining in importance because they can contribute to solving the problems arising from the world wide decline in the reserve to production ratio of crude oil, the emission of greenhouse gases and energy security. In Australia they can also assist in mitigating dry-land salinity by increasing the viability of large-scale plantation of locally indigenous trees. However significant technical and political ....Integrated Combustion Research Facility for Biomass Derived Fuels. Bio-mass derived fuels are gaining in importance because they can contribute to solving the problems arising from the world wide decline in the reserve to production ratio of crude oil, the emission of greenhouse gases and energy security. In Australia they can also assist in mitigating dry-land salinity by increasing the viability of large-scale plantation of locally indigenous trees. However significant technical and political issues remain to be addressed before this potential can be realised. The Integrated Combustion Research Facility for Biomass Derived Fuels to be established by this grant will provide the necessary infrastructure to address these issues.Read moreRead less
Turbulent wall-bounded flow in adverse pressure gradient environments. This research will create additional research capacity in turbulence control and drag reduction. It will have direct benefits to the Australian economy via the transport industry by reducing the adverse impact of the carbon tax and rising fuel prices on long-haul air, water and road transport, on which Australia is disproportionately reliant.

Lifting the Veil on Turbulent Convective Heat Transfer over Rough Surfaces. By understanding the influence of surface roughness on convective heat transfer, this project intends to reduce the unwanted heating and energy losses associated with surface roughness in gas and steam turbines used in power generation and transportation.

By understanding the influence of surface roughness on convective heat transfer, this project intends to reduce the unwanted heating and energy losses associated with surface roughness in gas and steam turbines used in power generation and transportation. The surface roughness that results from extended operation of gas and steam turbines can significantly increase the heating of their surfaces, increasing fuel consumption and greenhouse gas emissions, and reducing operational life. Improvements would allow turbines to operate at higher inlet temperatures which will increase their efficiency and reduce fuel use, environmental emissions and maintenance costs.Read moreRead less
Geometry of wall-turbulence and its potential to advance scalable models. This project aims to unravel the connections between the statistical geometry of wall-turbulence and the dynamical interactions of its instantaneous motions. Predicting the complex behaviour of turbulent fluid flow over surfaces in relative motion is central to atmospheric modelling for climate and agriculture, and reducing the environmental effect of fossil fuel usage. Wall-turbulence statistics organise according to a pr ....Geometry of wall-turbulence and its potential to advance scalable models. This project aims to unravel the connections between the statistical geometry of wall-turbulence and the dynamical interactions of its instantaneous motions. Predicting the complex behaviour of turbulent fluid flow over surfaces in relative motion is central to atmospheric modelling for climate and agriculture, and reducing the environmental effect of fossil fuel usage. Wall-turbulence statistics organise according to a predictable geometric structure, and the notorious complexity of turbulent wall-flow dynamics could be clarified through its inherent geometry. This project expects to construct a basis for predicting engineering and atmospheric wall-flows, which would enhance atmospheric flow prediction, reduce energy consumption and further environmental sustainability.Read moreRead less
Self-similar scale interactions in turbulent boundary layers. Predicting and controlling turbulent fluid flow next to a solid surface (the turbulent boundary layer) is of critical importance to ensuring a sustainable energy and environmental future.

Predicting and controlling turbulent fluid flow next to a solid surface (the turbulent boundary layer) is of critical importance to ensuring a sustainable energy and environmental future. While recent research has yielded a clearer physical understanding of these flows, converting this understanding into tools useful to engineering practice remains a central obstacle. The proposed research directly addresses this fundamental challenge by precisely connecting the eddy interactions of the turbulence to the mathematical equations that rigorously describe these flows. As such it holds breakthrough potential toward the development of turbulent boundary layer prediction and control schemes that do not rely on ad hoc models or assumptions.Read moreRead less

Expected outcomes of this project include greatly accelerated discovery of mechanisms leading to structural vibrations and optimising structure geometries to either enhance or suppress the vibrations. This should provide significant benefits, such as the design strategies for improved energy harvesters, such as current oscillators, or more stable structures, such as platforms for offshore wind turbines.
