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

Smart materials for atmospheric water management and water harvesting. Fresh water is a scarce resource in many parts of the globe but uncomfortably over-supplied in other regions. Dehumidifying machines, such as air conditioners, are extensively used in humid climates to enhance human comfort, but with great energy costs. Likewise, the production of potable water in remote dry regions is energy intensive. We propose novel hyper-absorbent desiccating polymers combined into sorption-powered engin ....Smart materials for atmospheric water management and water harvesting. Fresh water is a scarce resource in many parts of the globe but uncomfortably over-supplied in other regions. Dehumidifying machines, such as air conditioners, are extensively used in humid climates to enhance human comfort, but with great energy costs. Likewise, the production of potable water in remote dry regions is energy intensive. We propose novel hyper-absorbent desiccating polymers combined into sorption-powered engines inspired by nastic movements in plants to develop extremely efficient dehumidifiers and water harvesting machines. These polymer actuators can help address the auto-acceleration of climate change caused by the increasing use of air conditioners and provide cheap, clean water for remote communities.Read moreRead less
The impact of work-from-home environments on comfort and productivity. This project aims to quantify the effect of indoor environmental quality (IEQ) in work-from-home (WFH) settings on worker comfort, productivity and household energy use, by employing a longitudinal field monitoring approach.

This project aims to quantify the effect of indoor environmental quality (IEQ) in work-from-home (WFH) settings on worker comfort, productivity and household energy use, by employing a longitudinal field monitoring approach. This project expects to generate new knowledge that will inform current indoor environment standards and regulations to make them more relevant to our “new WFH normal”. Quantifying the impact of decentralised workforces on shifting energy usage between sectors can also help in the formulation of relevant energy efficiency policies and building codes. The project will provide significant benefits such as enhancing the quality of work-life of workers and enabling better management of residential energy use.Read moreRead less

Energy transitions: past, present and future. Uncertainty about the costs of transitioning to a low carbon economy in Australia and other countries will be reduced by improving our knowledge of the costs of reducing fossil fuel use and the role of energy in economic growth. Energy economics research capabilities in Australia will be enhanced.
Energy Efficiency Innovation, Diffusion and the Rebound Effect. This project aims to help quantify the net energy saved globally from energy efficiency policies and programs. It aims to investigate the speed at which energy efficiency innovations spread to countries across the world from technologically leading countries and to measure empirically the size of the rebound effect that offsets energy efficiency improvements at the economy-wide level.

This project aims to help quantify the net energy saved globally from energy efficiency policies and programs. It aims to investigate the speed at which energy efficiency innovations spread to countries across the world from technologically leading countries and to measure empirically the size of the rebound effect that offsets energy efficiency improvements at the economy-wide level. Governments and international organisations are increasingly looking to energy efficiency policies to reduce greenhouse gas emissions and improve energy security, but there is little information on the potential for these policies to actually save energy and, therefore, reduce emissions. Project results may help in the design of cost-effective energy and climate policies.Read moreRead less
Efficient, directional and spin-controlled nanoscale light sources. This project aims to develop a new class of functional light sources by harnessing the nanoscale interactions between emitters and metallic or dielectric nanoparticles.
