A new platform for poled glass waveguides in the mid-infrared. Mid-infrared light (beyond red out to what we feel as radiant heat) underpins many crucial applications that include the remote detection of explosives, chemicals and biological agents; dramatically speeding up internet communications; and even helping us detect planets in distant solar systems. The enormous cost of generating and analysing mid-infrared light using current technology has prevented many of these life-changing applicat ....A new platform for poled glass waveguides in the mid-infrared. Mid-infrared light (beyond red out to what we feel as radiant heat) underpins many crucial applications that include the remote detection of explosives, chemicals and biological agents; dramatically speeding up internet communications; and even helping us detect planets in distant solar systems. The enormous cost of generating and analysing mid-infrared light using current technology has prevented many of these life-changing applications coming to fruition. This project aims to change this and deliver technological leadership in this crucial field to Australia, thereby generating significant social and economic benefits. This project will also enhance Australia's international links and build on a range of national research programs.Read moreRead less
Precision inertial sensing with cold atoms. Many advances in our technology-driven society rely on precision measurement. The project will provide the Australian industrial and government sectors with new and better inertial sensors to measure acceleration, rotation and gravity. The technology will find application in navigation, defence, mineral exploration, earth science and fundamental physics.
Genesis and evolution of coherent structures in wall-bounded turbulence. This project aims to capture conditions responsible for the generation of the coherent structures that are formed in wall-bounded turbulent flows, through the use of variational data assimilation and adjoint-based optimisation techniques.

This project aims to capture conditions responsible for the generation of the coherent structures that are formed in wall-bounded turbulent flows, through the use of variational data assimilation and adjoint-based optimisation techniques. The project is expected to provide knowledge and intellectual property that is essential for the accurate modelling and prediction of the interaction between the ground-level activities like pollutant emissions and the atmosphere and the flow over vehicles through pipes, turbines and compressors. This project will provide benefits such as reducing the risk in environmental and commercial design and decision making and will facilitate new opportunities for the commercial development of devices to reduce drag and enhance mixing and heat transfer via the direct manipulation of coherent structures.Read moreRead less

Dynamics of Suppressed Mixing Regimes in Australian Rivers. This study aims to further the fundamental science of turbulent mixing in the context of flow in Australian rivers. The focus is on prolonged low flow conditions which when coupled with warm surface temperatures cause the water column to become thermally stratified which then suppresses turbulent mixing. The extreme scale of the river systems has made investigating the true dynamics of the strongly stratified mixing regimes particularly ....Dynamics of Suppressed Mixing Regimes in Australian Rivers. This study aims to further the fundamental science of turbulent mixing in the context of flow in Australian rivers. The focus is on prolonged low flow conditions which when coupled with warm surface temperatures cause the water column to become thermally stratified which then suppresses turbulent mixing. The extreme scale of the river systems has made investigating the true dynamics of the strongly stratified mixing regimes particularly challenging. By taking world first in-situ measurements of turbulent mixing and undertaking high resolution numerical simulations this study will provide definitive data which will allow correct characterization of the mixing regimes and how they are associated with river flow conditions.Read moreRead less

Wet granular materials are of immense economic importance in industries such as mining, agriculture, pharmaceuticals, and food processing. It has been estimated that operations involving the storage, handling and transport of granular materials account for over a third of the capital costs and over half of all the operating costs involved in process industries worldwide. An improved understanding of the dramatic effects of liquid on the cohesion, flow and mixing of granular materials will be of benefit to Australian industry both in terms of helping to reduce costly problems, such as caking and segregation, and in terms of the development of better particulate-based products, such as ceramics and pharmaceuticals.Read moreRead less
