This project will develop new fundamental knowledge and engineering models underpinning air-breathing high speed propulsion engines employing complex hydrocarbon fuels. Extensive data and new physical understanding will be garnered through analysis of direct numerical simulations of supersonic reacting mixing layers including impinging shock waves. That data will be employed to isolate, test and develop computationally efficient engineering models that are accurate and efficient for high speed combustion in rotating detonation engines and scramjets. Expected outcomes are knowledge and tools needed to develop practical and effective supersonic propulsion engines for access to space, defence and high speed point-to-point flight.

Gravity Current Driven Smoke Dispersion In a Stratified Ambient. Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniq ....Gravity Current Driven Smoke Dispersion In a Stratified Ambient. Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniques will be used to elucidate the fundamental mechanisms of gravity current entrainment and propagation. This knowledge will set a strong foundation to improve operational forecasts of smoke transport that will allow government agencies to better respond to the negative impact of these complicated flows.Read moreRead less
A multiplex microscope platform to define molecular events in fluid systems.

This project aims to develop a novel microscopy platform that will enable the visualisation and quantification of molecular events occurring under fluid shear stress. The project will generate new knowledge in platelet biology that will allow characterisation and prediction of key molecular and morphological changes occurring across a blood thrombus under flowing conditions as found in the blood vessels. These new tools and the imaging platform will have applications for researchers wishing to visualise small and rapid molecular events in four dimensions (length, width, height and across time) under fluid shear stress, which is applicable across a range of industries. The project expects to deliver the next generation of intravital microscopes that can visualise and quantify events in a challenging flow environment.Read moreRead less

This project aims to address vibrations of solid structures by utilising a combination of advanced experimental and computational methods. This project expects to generate new knowledge in the area of flow-induced vibrations utilising the new techniques of machine learning and evolutionary shape optimisation. 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.

Summary
PFAS source zone remediation by foam fractionation and in situ fluidisation. This project aims to develop two methods for the in situ remediation of per- and poly-fluroalkyl substances (PFAS) contamination, downhole foam fractionation for in situ groundwater treatment, and in situ fluidisation for soil treatment, both separately and in combination. Using these methods, PFASs will be removed in the form of a foam, which will be extracted as a liquid concentrate. These techniques could enable PFAS ....PFAS source zone remediation by foam fractionation and in situ fluidisation. This project aims to develop two methods for the in situ remediation of per- and poly-fluroalkyl substances (PFAS) contamination, downhole foam fractionation for in situ groundwater treatment, and in situ fluidisation for soil treatment, both separately and in combination. Using these methods, PFASs will be removed in the form of a foam, which will be extracted as a liquid concentrate. These techniques could enable PFAS removal efficiencies of greater than 90%, providing entirely new methods for the aggressive removal of PFAS from contaminated source zones. This project will enable the rapid removal of the bulk of the PFAS present in soils and groundwater and reduce the potential for further spreading.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 expects to derive a strategy for the setting of each machine in the farm, so that they collectively absorb or refl ....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 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

Mixing and air-sea coupling in the Pacific: Toward better El Nino forecasts. The Tropical Pacific drives significant year-to-year variability in Australian rainfall and climate extremes.

The Tropical Pacific drives significant year-to-year variability in Australian rainfall and climate extremes. However, tropical climate predictions are severely limited due to systematic biases in numerical climate models. Using new techniques and leveraging international collaborations, this project aims to transform our ability to simulate tropical Pacific climate through a new understanding of key air-sea interaction and ocean mixing processes. Expected outcomes include a better representation of tropical climate in the Australian climate model and improved seasonal to interannual predictive capability. These improved predictions will give communities more time to prepare for extreme events such as droughts, heatwaves and bushfires.Read moreRead less

The effect of this advance on stellar modelling could be profound since almost all stars contain convective regions. Many branches of astronomy rely on stellar models so the effect could extend far beyond the immediate field, ultimately expanding understanding of the Universe. It could also be crucial in realising the scientific advances of the surveys which are gathering data for up to a billion stars.Read moreRead less
