The project aims to provide the new understanding of, and computational design tools for, next generation solar thermal particle receivers and their hybrids. Particle receivers, which heat fine particles in suspension, offer much greater efficiency than current tubular receivers, but are presently unreliable due to the poor understanding of the complex and coupled mechanisms that govern their performance. The results are expected to speed up the development and roll-out of these devices, to deliver cost-effective, low-emissions energy technologies for future power generation and thermo-chemical processes. The aims will be met by the parallel application of advanced laser diagnostic measurements and computational fluid dynamics modelling techniques.Read moreRead less
Understanding particle-laden flows for clean high temperature processes. This project aims to understand and provide computational design tools for the complex heat and mass transfer processes within the new technologies that needed for the high temperature processing of minerals with low net carbon dioxide (CO2) emissions, both with and without the use of concentrated solar thermal energy.

This project aims to understand and provide computational design tools for the complex heat and mass transfer processes within the new technologies that needed for the high temperature processing of minerals with low net carbon dioxide (CO2) emissions, both with and without the use of concentrated solar thermal energy. These models are needed to achieve low-cost scale-up and development of the new technologies under development, because they operate in regimes of particle-laden flow for which present numerical design tools are unreliable. The project will underpin the development of new technologies that are needed for Australia to meet its greenhouse emissions targets and to capitalise on the anticipated global demand for low-carbon-intensive metals and other value-added products.Read moreRead less

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

This project aims to establish a cutting edge adaptive electrical capacitance volume tomography facility for real-time metering / imaging of multi-phase flows. Optimisation of these flows which are encountered in many industries, is paramount in today's carbon-constrained global economy. This project expects to generate the new knowledge necessary for such optimisations. Expected outcomes include enhanced national capability for characterisation of multi-phase flows in real-time under both ambient and high temperatures. This should benefit and greatly facilitate the commercial rollout of novel technologies in industrial sectors as diverse as mineral processing, clean energy, fuels/chemicals, oil/gas, food and environmental remediation.

Assessment of the aerodynamic behaviour of fibrous particles under well-defined conditions of relevance to bio-fuel combustion. Biomass is plant-derived fuel, which has the advantage of being greenhouse neutral. Biomass can potentially be utilised both in existing combustion technologies, after minor modifications, and in purpose-designed combustors. It is typically fed into a furnace or boiler as shredded particles, (e.g. of wood, straw or bagasse), with jet(s) of air, either alone or as part ....Assessment of the aerodynamic behaviour of fibrous particles under well-defined conditions of relevance to bio-fuel combustion. Biomass is plant-derived fuel, which has the advantage of being greenhouse neutral. Biomass can potentially be utilised both in existing combustion technologies, after minor modifications, and in purpose-designed combustors. It is typically fed into a furnace or boiler as shredded particles, (e.g. of wood, straw or bagasse), with jet(s) of air, either alone or as partial replacement of pulverised coal. However these particles are fibrous and, unlike round particles, their aerodynamic behaviour in such systems is poorly understood. The project will provide new understanding, data and models necessary to maximise efficiency and minimise emissions from the utilisation of these fuels.Read moreRead less

Controlling coastlines while generating power. The Project aims to produce strategies for protecting coasts from storms using farms of wave-energy machines, which also generate electricity. Increasing lengths of coast need protection as the climate changes, but conventional barriers create permanent environmental impacts and are a sunk cost usually borne by the taxpayer.

The Project aims to produce strategies for protecting coasts from storms using farms of wave-energy machines, which also generate electricity. Increasing lengths of coast need protection as the climate changes, but conventional barriers create permanent environmental impacts and are a sunk cost usually borne by the taxpayer. The Project expects to derive a strategy for the setting of each machine in the farm, so that they collectively absorb or reflect damaging waves under severe conditions. Under normal conditions, enough wave energy to sustain environmental processes would pass through. Sales of electricity would help to pay back the capital cost. Outcomes would include reduced coastal-erosion costs and a low-intermittency energy supply.Read moreRead less

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.
