Delivering a better understanding of unsteady wakes has real potential to further our future capabilities of reducing bluff body parasitic drag. The national benefit derived from this project is the advancement of knowledge of a complex fluid mechanics problem, with secondary benefits arising from the specific and practical application to sports aerodynamics. By better understanding the wake structure and its interaction with a locally oscillating bluff body this knowledge can feed into the field of active flow control in the transport sector. The potential for emissions mitigation by lowering aerodynamic losses in the ground transportation section through active aerodynamic control is significant.Read moreRead less
Designing textured roughness to control turbulent pipe flow. This project will combine a recent theoretical model of turbulent pipe flow with computer simulation to develop methods to control these flows (e.g. to increase mixing, reduce wall drag). Additionally we will extend the model so it can deal with many industrially significant flows of fluids carrying high concentrations of fine particles.

Summary
Advanced waste heat recovery systems. Vehicle emissions have recently driven the research, development, and commercialisation of Exhaust Gas Recirculation (EGR) systems. The development of novel EGR gas coolers for such systems will probably lead to the breakthrough necessary for advancing EGR technologies, benefiting Australian clean energy supplies in general and transport vehicles in particular. The project aims to produce lighter and cleaner EGR systems at lower costs. This project also aims ....Advanced waste heat recovery systems.

The development of novel EGR gas coolers for such systems will probably lead to the breakthrough necessary for advancing EGR technologies, benefiting Australian clean energy supplies in general and transport vehicles in particular. The project aims to produce lighter and cleaner EGR systems at lower costs. This project also aims to enhance the international reputation and impact of Australian research in the internationally focused fields of microporous materials and clean transport technology.Read moreRead less
Flame stabilisation and structure in axially staged combustion. We aim to improve fundamental understanding of flame stabilisation and structure in conditions relevant to axially staged combustion employed in gas turbines, in which an initial ultra-lean premixed stage is followed by a short residence time stage at higher equivalence ratios. This concept enables high turbine entry temperatures and thus high efficiency while limiting emissions of nitrogen oxides, and, importantly, enables improved ....Flame stabilisation and structure in axially staged combustion. We aim to improve fundamental understanding of flame stabilisation and structure in conditions relevant to axially staged combustion employed in gas turbines, in which an initial ultra-lean premixed stage is followed by a short residence time stage at higher equivalence ratios. This concept enables high turbine entry temperatures and thus high efficiency while limiting emissions of nitrogen oxides, and, importantly, enables improved operational flexibility in turndown and in burning fuels with different reactivities, such as hydrogen. This project will apply large-scale direct numerical simulations to advance fundamental understanding of this unusual combustion mode, and develop practical models able to predict its behaviour.Read moreRead less
Dynamic tomography: high-resolution, four-dimensional imaging of processes. This project will develop imaging technology that allows us to collect detailed, three dimensional movies of complex, microscopic processes in a laboratory. This technology will have applications in soil science, biology, oil extraction, and carbon sequestration.
Testing theories of two-phase fluid flow in porous media through experiment, imaging and modelling. The process underlying oil extraction, groundwater flow and the sequestration of carbon dioxide is that of one fluid pushing another out of the microscopic spaces in porous rocks and soils. Using the latest three-dimensional X-ray microscopes and computing technology, the project will image and model these fluid flows, allowing theories to be tested for the first time.
