Natural convection induced exchange flows between near shore and central regions of reservoirs. Inland discharges into reservoirs often carry rich nutrients, pollutants and biological species into the coastal regions, which are redistributed across the central regions of reservoirs through dynamical mixing processes. One of the important mixing processes is the horizontal exchange flow between the near shore and central regions induced by diurnal heating and cooling through the water surface, wh ....Natural convection induced exchange flows between near shore and central regions of reservoirs. Inland discharges into reservoirs often carry rich nutrients, pollutants and biological species into the coastal regions, which are redistributed across the central regions of reservoirs through dynamical mixing processes. One of the important mixing processes is the horizontal exchange flow between the near shore and central regions induced by diurnal heating and cooling through the water surface, which is classified as a natural convection process. This process will be investigated in this project through a closely linked analytical, experimental and numerical research program. The output from this research will have direct application in water quality management and environmental planning.Read moreRead less
Transport by Natural Convection in Reservoir Sidearms. This project is a first step in developing models of the distribution of water quality parameters in reservoirs by a range of small scale dynamical processes not included in commercial water quality models. Specifically, the project will investigate the transport of suspended materials from the shore to the deeper parts resulting from the interaction of the meteorological forcing and the topography. This will contribute to the development of ....Transport by Natural Convection in Reservoir Sidearms.

Specifically, the project will investigate the transport of suspended materials from the shore to the deeper parts resulting from the interaction of the meteorological forcing and the topography. This will contribute to the development of improved water quality models, and therefore to better management of water quality of Australia's water resources.Read moreRead less
Enabling low greenhouse gas emissions from road vehicles through the proper use of alternative fuels. A major increase in alternative transport fuel use appears necessary in our response to the challenges of climate change and energy security. This proposal will advance our fundamental understanding of key aspects of the combustion of particular alternative fuels, thus enabling proper engine design and so maximising greenhouse and energy security benefits. Further, the Australian automotive indu ....Enabling low greenhouse gas emissions from road vehicles through the proper use of alternative fuels. A major increase in alternative transport fuel use appears necessary in our response to the challenges of climate change and energy security. This proposal will advance our fundamental understanding of key aspects of the combustion of particular alternative fuels, thus enabling proper engine design and so maximising greenhouse and energy security benefits. Further, the Australian automotive industry is a major employer and exporter, and needs to develop and/or maintain international leadership in low emission technologies to ensure its long term viability. This proposal builds a consortium of local organisations with common interests, thus helping local industry respond to several, significant challenges that they presently face.Read moreRead less
Quantification of heat release, NOx emissions and soot from high temperature gaseous flames. 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 c ....Quantification of heat release, NOx emissions and soot from high temperature gaseous flames. 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.

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

Advanced Laser Diagnostics in Dilute Heterogeneous Combustion. This proposal seeks to establish a state-of-the-art laser diagnostics facility with unique capabilities for non-intrusive measurements in dilute multi-phase flows.

This proposal seeks to establish a state-of-the-art laser diagnostics facility with unique capabilities for non-intrusive measurements in dilute multi-phase flows. Such heterogeneous flows which involve stationary surfaces, disperse suspended droplets or suspended particles are found in many applications including engines, furnaces, industrial and chemical processing and micro-combustion devices. This facility will give Australian researchers the unprecedented opportunity to perform measurements of flow, mixing, temperature and composition fields in the gas and liquid or solid phases simultaneously. The resulting data will advance current knowledge in these complex flows and lead to new and improved reactor designs.
