Dynamics and control of fluid-structure-free surface interactions. This project aims to research the apparently opposing effects of vortex shedding and free surface damping, individually and jointly, and the control or excitation of the vibrations for two generic bluff bodies: the cylinder and the sphere. Flow-induced vibrations of bluff bodies under or piercing water surfaces can damage floating off-shore marine structures and tethered bodies. On the other hand, harvesting energy from ocean cur ....Dynamics and control of fluid-structure-free surface interactions. This project aims to research the apparently opposing effects of vortex shedding and free surface damping, individually and jointly, and the control or excitation of the vibrations for two generic bluff bodies: the cylinder and the sphere. Flow-induced vibrations of bluff bodies under or piercing water surfaces can damage floating off-shore marine structures and tethered bodies. On the other hand, harvesting energy from ocean currents needs large flow-induced vibrations. The intended outcomes are new modes of body vibration, wake transitions and means to control fluid-structure interactions. This research could benefit many processes in offshore marine engineering, submarine bodies and mixing vessels, where understanding and controlling fluid-structure interactions of bluff bodies can mitigate costly and dangerous induced vibrations.Read moreRead less

Flow measurement for large-scale industrial aerodynamics. This project aims to research the unsteady aerodynamic wakes of cars, trucks, athletes, turbines and micro-air vehicles. Researchers will use the flow measurement system for large-scale industrial aerodynamics to resolve high speed and large scale industrial flows.

This project aims to research the unsteady aerodynamic wakes of cars, trucks, athletes, turbines and micro-air vehicles. Researchers will use the flow measurement system for large-scale industrial aerodynamics to resolve high speed and large scale industrial flows. The system’s primary objective will be the characterisation of complex, three-dimensional turbulent flows. It is anticipated that the research will lead to reduced aerodynamic drag in transport and improve wind power generation, ultimately reducing emissions and improving efficiency and national competitiveness in sport. The advanced system will strengthen Australia’s position as an advanced engineering design hub.Read moreRead less
Wake Transitions and Fluid-Structure Interactions of Rotating Bluff Bodies. Flow-induced vibrations of bluff bodies can lead to severe damage in many applications, such as off-shore marine structures and tethered bodies. Rotation of bluff bodies can result in huge increases in lift forces, which may promote these vibrations, whereas a nearby free surface may stabilise the vibrations. This project aims to discover the mechanisms underpinning the apparently opposing effects of vibration and free s ....Wake Transitions and Fluid-Structure Interactions of Rotating Bluff Bodies. Flow-induced vibrations of bluff bodies can lead to severe damage in many applications, such as off-shore marine structures and tethered bodies. Rotation of bluff bodies can result in huge increases in lift forces, which may promote these vibrations, whereas a nearby free surface may stabilise the vibrations. This project aims to discover the mechanisms underpinning the apparently opposing effects of vibration and free surface, individually and jointly, and the excitation of two- and three-dimensional instabilities in the wakes of two generic bluff bodies: the cylinder and the sphere. The expected outcomes are the discovery of new modes of body vibration, wake transitions and means to control fluid-structure interactions.Read moreRead less
Dynamics of bluff body interactions with walls. Spherical bodies are continually impacting or rolling on solid surfaces, from leukocytes to dust grains to golf balls, and larger. A joint Australian-French team will pioneer new research on the flow and mixing created by these bodies and understand the role these play in important commercial and environmental flows.

Integrated Combustion Research Facility for Biomass Derived Fuels. Bio-mass derived fuels are gaining in importance because they can contribute to solving the problems arising from the world wide decline in the reserve to production ratio of crude oil, the emission of greenhouse gases and energy security. In Australia they can also assist in mitigating dry-land salinity by increasing the viability of large-scale plantation of locally indigenous trees. However significant technical and political ....Integrated Combustion Research Facility for Biomass Derived Fuels. Bio-mass derived fuels are gaining in importance because they can contribute to solving the problems arising from the world wide decline in the reserve to production ratio of crude oil, the emission of greenhouse gases and energy security. In Australia they can also assist in mitigating dry-land salinity by increasing the viability of large-scale plantation of locally indigenous trees. However significant technical and political issues remain to be addressed before this potential can be realised. The Integrated Combustion Research Facility for Biomass Derived Fuels to be established by this grant will provide the necessary infrastructure to address these issues.Read moreRead less
Turbulent wall-bounded flow in adverse pressure gradient environments. This research will create additional research capacity in turbulence control and drag reduction. It will have direct benefits to the Australian economy via the transport industry by reducing the adverse impact of the carbon tax and rising fuel prices on long-haul air, water and road transport, on which Australia is disproportionately reliant.
