We will attack industrially-important problems in fluid mechanics by building new, and substantially enhancing existing, international collaborations between key complementary teams of internationally-recognised French and Australian researchers. Funding will support the exchange of 6 senior staff and 3 graduate students, which, in turn, will measurably benefit the research output of a further 20 graduate students and 7 post-doctoral fellows associated with closely-related projects. From the Australian perspective, the planned exchanges will bring new research expertise, knowledge and skills, which will be focussed on a diverse range of applications. Target industries (with existing collaborations) include Airbus and Dassault Aviation in Europe, and Aerosonde and Warman pumps in Australia. Read moreRead less

The development of active third-generation heavy vehicle aerodynamic drag reducing devices to reduce future transport emissions. The potential for emission reductions through aerodynamic improvements is particularly apparent in long haul heavy vehicle transport. By developing active devices to be fitted to the heavy vehicle trailer of the future this work offers drag reduction potential from current levels of up to 40 per cent. If widely implemented these devices could play a major part in the t ....The development of active third-generation heavy vehicle aerodynamic drag reducing devices to reduce future transport emissions. The potential for emission reductions through aerodynamic improvements is particularly apparent in long haul heavy vehicle transport. By developing active devices to be fitted to the heavy vehicle trailer of the future this work offers drag reduction potential from current levels of up to 40 per cent. If widely implemented these devices could play a major part in the transport sector meeting medium term emissions targets. If successful not only will the project develop unique components, it will support heavy vehicle research and development that is so important to maintaining a strong manufacturing presence in Australia, especially in regional centres, such as Ballarat where Maxitrans has major headquarters.

The structure of turbulent boundary layers. This research has an enormous impact in many fields of engineering - for example, in aeronautical, mechanical, chemical, meteorological and biomedical engineering. The resulting energy and economic savings and the reduction in atmospheric pollution and greenhouse gasses will ultimately impact on areas such as global climatic change and the energy sustainability of our urban environment, thus influencing the well-being of all people living on this plan ....The structure of turbulent boundary layers.

Wall Turbulence Drag: Physical Mechanisms and Practicable Control Strategies. The proposed research will build on Australia's well-established strengths in Fluid Mechanics, and aim to establish within Australia world-leading expertise in turbulence control and drag reduction technology. This will have direct benefits to the Australian economy through Tourism (among other industries) by reducing the adverse impact of rising fuel prices on long-distance air travel, on which Australia is disproport ....Wall Turbulence Drag: Physical Mechanisms and Practicable Control Strategies. The proposed research will build on Australia's well-established strengths in Fluid Mechanics, and aim to establish within Australia world-leading expertise in turbulence control and drag reduction technology. This will have direct benefits to the Australian economy through Tourism (among other industries) by reducing the adverse impact of rising fuel prices on long-distance air travel, on which Australia is disproportionately reliant due to its geographic isolation. Efficient turbulence control strategies will also lead to improved combustion processes, resulting in not only better fuel efficiency but also reduced CO2 and pollutant emissions.Read moreRead less
Wave slam on high speed wave piercing catamaran ferries in large seas. Australia has taken a pioneering lead in the design of high speed multi-hull ferries and continues to extend their speed, range and payload performance. Design leadership and the technology which supports it are crucial to maintaining the existing large share of the international market for such vessels.

Australia has taken a pioneering lead in the design of high speed multi-hull ferries and continues to extend their speed, range and payload performance. Design leadership and the technology which supports it are crucial to maintaining the existing large share of the international market for such vessels. Recently freight and military transport vessels have been exposed to much more severe wave conditions than passenger vessels and this has increased the need for improved prediction of structural loads due to waves. This project directly addresses that need by computation and model testing validation. The industry is a significant export earner and employer within Australia and so the project directly underpins those national benefits. Read moreRead less

The project aims to develop an understanding of the engineering and physical principals that determines the performance of a class of scramjet operating at hypervelocity speeds (>3km/s). Novel and innovative ideas will be explored which for the first time will provide the understandings necessary to make well founded predictions of the cost effectiveness of this approach, as well as provide the blue print to develop an engine which can operate at Mach 10.Read moreRead less
Development of large scale expansion tubes. The aim of this proposal is to develop a high Mach number scramjet simulation capability by modifying the X3 superorbital expansion tube at UQ for high suborbital operation at very high total pressures. This will enable Australia to do true Mach number simulation at higher speeds than is possible anywhere else, and mantain an international advantage in the development of scramjet flight propulsion.

This will enable Australia to do true Mach number simulation at higher speeds than is possible anywhere else, and mantain an international advantage in the development of scramjet flight propulsion. It will also put Australian researchers in a strong position to participate in the next generation of US ground testing facilities, foreshadowed by the recent NASA purchase of a large shock tunnel driver. It will enable Australia to maintain a position of leadership in the development of new space travel concepts.Read moreRead less
Optimal nose shaping for delayed boundary-layer separation and transition in axisymmetric flow. The aim of this project is to design a smooth nose for a body of revolution placed in axisymmetric flow of a viscous fluid at high Reynolds number, such that the boundary layer on the body remains unseparated. This can always be done with a sufficiently long nose, but our objective here is to minimise the necessary nose length. Outer potential flows will be provided via ring sources. The potential flo ....Optimal nose shaping for delayed boundary-layer separation and transition in axisymmetric flow. The aim of this project is to design a smooth nose for a body of revolution placed in axisymmetric flow of a viscous fluid at high Reynolds number, such that the boundary layer on the body remains unseparated. This can always be done with a sufficiently long nose, but our objective here is to minimise the necessary nose length. Outer potential flows will be provided via ring sources. The potential flows will be used to determine inner boundary layer solutions. Transition-to-turbulence will be considered by undertaking 2D and 3D stability computations.Read moreRead less
