Thermal overheating can affect the capacity, safety and life expectancy of batteries for renewable energy storage and electric vehicles. Microscale heat exchangers are a potential high-efficiency, low-bulk solution. This project aims to develop a novel computational methodology to optimise the design of those heat exchangers in which viscoelastic fluids are used to control flow instabilities and enhance heat transfer at the microscale. A new microscopic fluid physics model will provide data for an innovative neural network framework to optimise the working fluid conditions and microscale design, which could contribute to increased adoption of renewable energy technologies that are supported by microscale heat exchangers.Read moreRead less

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

Reactivity and photochemistry of halide anions: atmospheric implications. Bromine and iodine are suspected to be responsible for most of the halogen-induced ozone loss in the stratosphere but are not currently included in atmospheric models due to a paucity of knowledge of the gas-phase chemistry and photochemistry of their anions and radicals. This project will develop and deploy advanced mass spectrometry and laser spectroscopy techniques to enable precision measurements of the reactions and p ....Reactivity and photochemistry of halide anions: atmospheric implications. Bromine and iodine are suspected to be responsible for most of the halogen-induced ozone loss in the stratosphere but are not currently included in atmospheric models due to a paucity of knowledge of the gas-phase chemistry and photochemistry of their anions and radicals. This project will develop and deploy advanced mass spectrometry and laser spectroscopy techniques to enable precision measurements of the reactions and photo-reactions of gas-phase iodide and bromide anions and their oxides. These state-of-the-art measurements of reaction kinetics and products will enable accurate chemical models that predict the impact of bromine and iodine chemistry on ozone levels and will inform future models for global climate.Read moreRead less

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

Shock-wave turbulent-boundary-layer interactions occur on hypersonic flight vehicles and can lead to high heating and increased drag. This is a paramount design issue that needs addressing. We aim to understand and quantify fundamental phenomena occurring in such interactions using state-of-the-art instrumentation and wind-tunnel facilities. Surfaces will be heated to realistic flight temperatures to simulate accurately the flight environment and include effects not reproduced with cold models. The effects of 3D features of the interactions will lead to new understanding of how the flow develops through a combination of experiments and numerical simulations. Future designs of hypersonic flight vehicles will benefit from knowledge gained.Read moreRead less
