Summary
Facilities for Atmospheric Boundary Layer Evaluation and Testing. This proposal aims to establish state-of-the-art stationary and mobile facilities for atmospheric wind, dust and plume measurements with unique capability to quantify the effect of climate change, surface topography and urbanisation on near-surface microclimate where humans live.

This proposal aims to establish state-of-the-art stationary and mobile facilities for atmospheric wind, dust and plume measurements with unique capability to quantify the effect of climate change, surface topography and urbanisation on near-surface microclimate where humans live. To better predict microclimate, mitigate air pollution impacts and exploit local conditions for improved urban planning and agricultural yield, high quality observations of the near-surface atmosphere at fine temporal and spatial resolutions are required. The proposed Facilities for Atmospheric Boundary Layer Evaluation and Testing (FABLET) will advance Australia’s capability to make these difficult measurements of atmospheric boundary layer.Read moreRead less

Summary
Noise-reduction mechanisms in jet engines: chevrons are the answer. This project aims to develop new models to study the influence of chevrons on the exhaust of aircraft engines, which is one of the strongest sound sources during take-off. As constant exposure to high-amplitude noise in areas close to airports leads to a myriad of health problems, new strategies have been sought to mitigate this noise component. Chevrons may modify the dynamics of the noise-generating coherent structures, but mo ....Noise-reduction mechanisms in jet engines: chevrons are the answer. This project aims to develop new models to study the influence of chevrons on the exhaust of aircraft engines, which is one of the strongest sound sources during take-off. As constant exposure to high-amplitude noise in areas close to airports leads to a myriad of health problems, new strategies have been sought to mitigate this noise component. Chevrons may modify the dynamics of the noise-generating coherent structures, but most of their parameters are chosen by trial and error, and the mechanism that maximises noise reduction is not clear. By understanding the underlying noise-reduction mechanisms, this project will facilitate the optimal design of quieter exhaust nozzles, ameliorating the effect of aircraft noise on the local community.Read moreRead less
THE BASAL MELTING OF ANTARCTIC ICE SHELVES . The project aims to determine the mechanisms that govern melting of Antarctic ice shelves into the ocean. Faster basal melting of ice shelves in the warming ocean is contributing to loss of grounded ice from Antarctica and increased glacier speeds, and melting is projected to become a larger contribution to future global sea level rise. Using unique laboratory experiments, turbulence-resolving computation and theoretical analysis the project will eva ....THE BASAL MELTING OF ANTARCTIC ICE SHELVES . The project aims to determine the mechanisms that govern melting of Antarctic ice shelves into the ocean. Faster basal melting of ice shelves in the warming ocean is contributing to loss of grounded ice from Antarctica and increased glacier speeds, and melting is projected to become a larger contribution to future global sea level rise. Using unique laboratory experiments, turbulence-resolving computation and theoretical analysis the project will evaluate the roles of meltwater, ocean currents, internal wave breaking and water exchanges between the continental shelf and sub-ice cavities. The results will assist our understanding of measurements made in Antarctica and more reliable predictions of sea level rise.Read moreRead less
Expanding the scramjet operating envelope through oxygen enrichment. This project aims to investigate the benefits of expanding the operating envelope of scramjets to higher altitudes and speeds by enriching their fuel with oxygen. This is expected to enhance the performance and flexibility of hypersonic air-breathing engines designed to form the core of a more reliable and economical access to space system. Expected outcomes of this project are a validated understanding and mapping of how oxyge ....Expanding the scramjet operating envelope through oxygen enrichment. This project aims to investigate the benefits of expanding the operating envelope of scramjets to higher altitudes and speeds by enriching their fuel with oxygen. This is expected to enhance the performance and flexibility of hypersonic air-breathing engines designed to form the core of a more reliable and economical access to space system. Expected outcomes of this project are a validated understanding and mapping of how oxygen enrichment can augment scramjet thrust at high altitudes and speeds, and a performance evaluation of a launch system optimised for this approach. This could provide significant benefits to the performance of reusable, air-breathing launch technology, where Australia is leading the push towards commercialisation.Read moreRead less
Thermal Optimisation of Gigascale Solar Photovoltaics. Large-scale solar photovoltaics are critical to decarbonising the global economy. Sun Cable is developing the world’s largest solar farm in the Northern Territory, and is considering deploying the 5B MAV solar array. At this scale, temperature-induced panel efficiency losses represent a major challenge that must be overcome through thermal performance optimisation. We will build sophisticated multiscale models to simulate and understand the ....Thermal Optimisation of Gigascale Solar Photovoltaics. Large-scale solar photovoltaics are critical to decarbonising the global economy. Sun Cable is developing the world’s largest solar farm in the Northern Territory, and is considering deploying the 5B MAV solar array. At this scale, temperature-induced panel efficiency losses represent a major challenge that must be overcome through thermal performance optimisation. We will build sophisticated multiscale models to simulate and understand the multiple interacting phenomena that cause panel heating, for the first time. This project will create the tools and know-how to optimise array design and solar farm development, delivering major efficiency gains and enhancing the viability of future gigascale solar projects.Read moreRead less
Towards highly-efficient hydrogen gas turbines. The increasing interest in green hydrogen has led to a need for research and development in combustion systems that can accommodate hydrogen. One promising technology is low-emission gas turbines, which is a key player in the electricity market. However, hydrogen gas turbines are susceptible to a phenomenon called thermoacoustic instability, causing loud noise and can damage equipment. This project represents the first comprehensive study of the ef ....Towards highly-efficient hydrogen gas turbines. The increasing interest in green hydrogen has led to a need for research and development in combustion systems that can accommodate hydrogen. One promising technology is low-emission gas turbines, which is a key player in the electricity market. However, hydrogen gas turbines are susceptible to a phenomenon called thermoacoustic instability, causing loud noise and can damage equipment. This project represents the first comprehensive study of the effects of hydrogen fuel on thermoacoustic instability under conditions relevant to gas turbines. By examining low-order models, commonly used for designing gas turbines, this project can significantly advance the field and facilitate the adoption of green hydrogen as a fuel source.Read moreRead less
