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
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

The structure of turbulence at high Reynolds numbers. The aim of this project is to gain a physical understanding of the process of turbulence in fluid motion, focusing on boundary layers adjacent to the surface of bodies, such as submarines and turbines. As turbulence is of fundamental importance in many engineering tasks, developing our understanding of the mechanisms involved will lead to progress in many areas.

As turbulence is of fundamental importance in many engineering tasks, developing our understanding of the mechanisms involved will lead to progress in many areas. For example, accurate prediction of drag on vehicles, aircraft and ships, resulting in reductions in fuel consumption. The wind tunnel used in this project is the largest of its type in the world, enabling pioneering experiments to be undertaken which will extend our understanding of the physics of turbulence for applied flows.

Practical wall-turbulence drag reduction through adaptive control. Long term increases in the price of aviation fuel disproportionately impacts on Australian carriers, given our geographic isolation and the resulting greater percentage of long-haul flights. The resulting higher fares will also have a direct impact on international tourism to Australia. One way to reduce the impact of rising fuel cost, and to reduce CO2 and other emissions at the same time, is to decrease drag on aircraft. This ....Practical wall-turbulence drag reduction through adaptive control. Long term increases in the price of aviation fuel disproportionately impacts on Australian carriers, given our geographic isolation and the resulting greater percentage of long-haul flights. The resulting higher fares will also have a direct impact on international tourism to Australia. One way to reduce the impact of rising fuel cost, and to reduce CO2 and other emissions at the same time, is to decrease drag on aircraft. This project will develop understanding in wall turbulence and adaptive control, and use this to experimentally demonstrate active reductions in skin friction drag. The results are equally applicable to a range of other applications including sea transport, pipe flows and combustor designs.Read moreRead less
