Fluid-structural interactions in high-speed flows. This project aims to perform experiments to measure fluid-structure interaction in hypersonic flows. The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters.

The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters. Accurate prediction of the behaviour and lifetime of structural components subject to these fluid-structural interactions, in which the deformation of the structure induced by the local flow field, can in turn influence this flow field. This coupling can result in damage or even catastrophic structural failure and thus robust design tools must be developed to avoid this.Read moreRead less
Physics of Base Flows of Planetary Entry Configurations. Continued investment by Australia in the AHI will help to maintain Australia's leading role in the exciting fields of space research and hypersonics and to encourage future international collaboration.

The research will use the unique existing experimental infrastructure (largely ARC funded) for space related research, which will enable Australia to make a valuable contribution to the design of future planetary missions. The project will provide a stimulating, exciting and supportive environment for the training of postgraduate and postdoctoral personnel as well as students at the undergraduate level. It will help to motivate young Australians to pursue their interest in science and engineering.Read moreRead less
Rarefied hypervelocity separated flow in the transitional to continuum regimes. The transition regime for low-density flows is a no-man's-land between free-molecular and continuum flow, where the flow behaves differently to the assumptions typically used for modelling either flow type. Bird's direct Simulation Monte Carlo (DSMC) method is typically thought to be the best way of modelling these flows, but has not produced excellent agreement with previous experiments on low-density separated flow ....Rarefied hypervelocity separated flow in the transitional to continuum regimes. The transition regime for low-density flows is a no-man's-land between free-molecular and continuum flow, where the flow behaves differently to the assumptions typically used for modelling either flow type. Bird's direct Simulation Monte Carlo (DSMC) method is typically thought to be the best way of modelling these flows, but has not produced excellent agreement with previous experiments on low-density separated flows, due to computational limitations and lack of knowledge of the flow's internal energy. This proposal is a blind test of the best current DSMC codes against our experiments and a hypersonic continuum code, with the full internal energy state of the flow experimentally quantified for the first time.Read moreRead less

A sensitive tip-tilt wavefront sensor for the multi-conjugate adaptive-optics system on the Gemini South telescope: This project will construct a sensitive tip-tilt wavefront sensor for GeMS, the multi-conjugate adaptive-optics system on the Gemini South telescope in Chile. GeMS is a unique and revolutionary new system that delivers near-infrared images at similar resolution to the Hubble Space Telescope at optical wavelengths over wide fields. With this improvement in technology it will be possible to do this on much fainter objects than is currently possible using this new wave-front sensor. This will allow GeMS to routinely study the morphologies of external galaxies at high angular resolution - greatly extending its science scope. Sharper images will also be obtained for all objects that are currently accessible, leading to higher quality science data.Read moreRead less

A database for Australian optical astronomy. We will build an astronomy data facility to provide database facilities to analyse data from three major Australian optical astronomy projects, SkyMapper, WiggleZ and GAMA. The facility will provide efficient analysis tools not only for the researchers immediately involved with the projects, but, for the entire national and international astronomical community when the data become public.

The facility will provide efficient analysis tools not only for the researchers immediately involved with the projects, but, for the entire national and international astronomical community when the data become public. Long-term maintenance of the facility is vital, so the facility will be standards-compliant and stable to facilitate long-term support. For this reason the facility will be based at the ANU Supercomputer Facility (ANUSF) to leverage substantial expertise in this area and to provide long-term operations support.Read moreRead less
