Summary
Strengthening merit-based access and support at the new National Computing Infrastructure petascale supercomputing facility. World-leading high-performance computing is fundamental to Australia's international research success. This facility will provide access to the new National Computational Infrastructure facility by world-leading researchers from six research universities, and sustain ground-breaking work in an increasingly competitive environment.
A fundamental study of milk ultrafiltration. The Dairy Industry is one of Australia's largest domestic and export industries. The fundamental knowledge and models developed in this project will be used to optimise dairy membrane processing. This will reduce water and energy use to improve the global competitiveness and reduce the environmental impact of the Australian Dairy Industry.

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.

Transition of thermal boundary layers on heated flat and curved surfaces. This project aims to study the laminar to turbulent transition of the thermal boundary layer (TBL). The state of the TBL determines the heat transfer rate and energy efficiency of natural convection heat exchangers and heat dissipation systems. The intended outcome is to understand the TBL’s transitional behaviour and develop effective strategies for stimulating TBL transition to enhance heat transfer.

The state of the TBL determines the heat transfer rate and energy efficiency of natural convection heat exchangers and heat dissipation systems. The intended outcome is to understand the TBL’s transitional behaviour and develop effective strategies for stimulating TBL transition to enhance heat transfer. This project will develop a high-resolution, low-cost and easy-to-implement three-dimensional volumetric flow measurement technique based on stereoscopic shadowgraph and use it to study the TBL transition. This technique should provide a powerful tool for fluid mechanics and heat transfer research.Read moreRead less
Entrainment and Mixing in Turbulent Negatively Buoyant Jets and Fountains. The project intends to develop tools to accurate predict fountain flows. Volcanic eruptions, building ventilation and brine discharge from desalination plants are all examples of turbulent fountains and negatively buoyant jets. The project aims to conduct an investigation into the turbulent structure of fountains and negatively buoyant jets using numerical simulation and laboratory experiments, and to assess the accuracy ....Entrainment and Mixing in Turbulent Negatively Buoyant Jets and Fountains. The project intends to develop tools to accurate predict fountain flows. Volcanic eruptions, building ventilation and brine discharge from desalination plants are all examples of turbulent fountains and negatively buoyant jets. The project aims to conduct an investigation into the turbulent structure of fountains and negatively buoyant jets using numerical simulation and laboratory experiments, and to assess the accuracy of the commonly used integral models and test the effect of the use of more accurate entrainment relations. This may have a range of applications – enabling better prediction of environmental impacts, reduction of the adverse effects of the discharge of pollutants, and reduction in energy consumption in building ventilation and other industrial applications.Read moreRead less
Large Scale Natural Convection Boundary Layers with Non-Boussinesq Effects. This proposal aims to understand and predict heat transfer by turbulent natural convection in two scenarios, firstly at very large environmental scales, such as occur on melting Antarctic ice sheets, and secondly convection involving very large temperature differences such as occur in solar thermal power plants and industrial processes. These natural convection flow regimes are incredibly difficult to investigate directl ....Large Scale Natural Convection Boundary Layers with Non-Boussinesq Effects. This proposal aims to understand and predict heat transfer by turbulent natural convection in two scenarios, firstly at very large environmental scales, such as occur on melting Antarctic ice sheets, and secondly convection involving very large temperature differences such as occur in solar thermal power plants and industrial processes. These natural convection flow regimes are incredibly difficult to investigate directly but by focusing on the fundamental dynamics of the turbulent flows using large scale numerical simulations and innovative experiments, the project is expected to develop better analytical and computational models which will underpin improvements in
global ocean models and improve energy efficiency.Read moreRead less
Thermal stratification, overturning and mixing in riverine environments. Thermal stratification is common in Australia's rivers due to our hot, drought-prone climate and high human demands relative to available supply, which has led to a significant reduction in flows relative to natural levels. Thermal stratification inhibits mixing, creating stagnant conditions characterised by low oxygen levels and increased concentrations of contaminants, leading to algal blooms, fish kills and systemic dama ....Thermal stratification, overturning and mixing in riverine environments. Thermal stratification is common in Australia's rivers due to our hot, drought-prone climate and high human demands relative to available supply, which has led to a significant reduction in flows relative to natural levels. Thermal stratification inhibits mixing, creating stagnant conditions characterised by low oxygen levels and increased concentrations of contaminants, leading to algal blooms, fish kills and systemic damage to ecosystems. The aim of this project is to develop predictive models for the effects of physical processes such as night-time cooling, wind, turbulence and currents on riverine thermal stratification. This is expected to enable a more accurate determination of the flow rates required to maintain the health of our river systems.Read moreRead less
The dynamics of turbulent entrainment in sheared convective boundary layers. This project aims to develop general laws to enable the accurate prediction of boundary layer entrainment processes. This will be significant in a wide range of environmental and engineering applications. In particular, the current lack of understanding of this area is a major source of uncertainty in the latest generation of global climate models.
Biotransport design for engineering microenvironment in scaffolds. Tissue engineering signifies an exciting opportunity to solve shortage of transplantable tissues. This project targets a critical issue in engineering thick tissue and aims to introduce computational structural optimisation to biotransport problems. The optimal scaffold is expected to create a more desirable microenvironment for better tissue growth.

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
