Resolving the mechanics of wind turbine noise production. This project will investigate how wind turbines produce noise. It will do this by developing the most sophisticated wind turbine noise experiment in the world, which will allow the construction of better designed wind farms, better public policy and new noise control technologies.
Investigating the coupled dependencies of soot in turbulent flames by advanced laser diagnostics and modelling. The community will benefit from the project by reduced air pollution and improved health and safety. Soot is a major air pollutant, adversely effecting public health, while also contributing directly to global warming. It also dominates heat transfer and influences the emissions of NOx and CO2.

The community will benefit from the project by reduced air pollution and improved health and safety. Soot is a major air pollutant, adversely effecting public health, while also contributing directly to global warming. It also dominates heat transfer and influences the emissions of NOx and CO2. The project will significantly advance detailed understanding and modelling capability of flames containing soot. Hence it will provide significantly improved capability to optimise these flames in applications spanning gas turbines, power generation, minerals processing and fires.Read moreRead less
A novel approach to controlling boundary-layer separation. This project will involve fundamental research into the control of the fluid dynamical phenomena of boundary-layer separation and transition to turbulence. The project will be built upon a firm foundation of mathematical modelling of the complex behaviour of fluid flows that are near the onset of flow separation or turbulence. The project will produce results that will permit the development of control strategies that can be implemented ....A novel approach to controlling boundary-layer separation. This project will involve fundamental research into the control of the fluid dynamical phenomena of boundary-layer separation and transition to turbulence. The project will be built upon a firm foundation of mathematical modelling of the complex behaviour of fluid flows that are near the onset of flow separation or turbulence. The project will produce results that will permit the development of control strategies that can be implemented in a wide variety of important technological applications, such as drag reduction in the aerospace and ship industries as well as the control of stall (or loss of lift) in modern aircraft.Read moreRead less
Detailed understanding of the behaviour of soot in, and emission from, turbulent flames and fires. While combustion processes involving soot have been widely employed for many years, their great complexity puts them beyond present capacity to understand or model reliably. Within a flame, soot plays an important role in radiant heat transfer, and hence in energy efficiency. Beyond a flame, soot can either be emitted as an unwanted air pollutant or as a desirable source of nano-particles, dependin ....Detailed understanding of the behaviour of soot in, and emission from, turbulent flames and fires. While combustion processes involving soot have been widely employed for many years, their great complexity puts them beyond present capacity to understand or model reliably. Within a flame, soot plays an important role in radiant heat transfer, and hence in energy efficiency. Beyond a flame, soot can either be emitted as an unwanted air pollutant or as a desirable source of nano-particles, depending on the application. The benefits to society from improved understanding and predictive capability include reduced air pollution, improved health and safety, increased efficiency in the utilisation of both fossil and alternative fuels, the support of the rapidly growing sector employing carbon nano-particles and increased fire safety.

will be based systematically upon established turbulence models to
resolve accurately the complex physical processes. The development of
new and robust computer models for thin layers of coating fluid will
aid many industrial processes. We also aim to provide correct initial
conditions and boundary conditions for simpler cases of the above
flows. The approach leads to a greater understanding of the range of
applicability of the models through better estimating the errors in the
modelling process. The project develops a fundamental enabling
methodology for engineering and the sciences.

This project aims to study gaseous flames under heat and gas recirculation conditions. This technology has been proven to reduce fuel consumption, improve thermal efficiency and substantially reduce nitric oxides emission. The effect of mixing, turbulence and temperature on the structure and stability of these flames will be investigated. The project combines experimental and computational research applied to a laboratory scale burner and a small scale furnace. The main objectives are to better understand the chemical pathways in low temperature hydrocarbon flames under heat and gas recirculation conditions and to understand the effect of mixing and turbulence on the flame structure and pollutants emission.Read moreRead less
New understanding of turbulent flames with soot and particulate fuels. This project will develop the new understanding and models required to optimise practical furnaces, boilers and combustion chambers, most of which involve soot and/or particulate fuels. This work will be performed with state-of-the-art measurement and modelling tools through a well-established partnership of international researchers.
Resolving the mechanics of turbulent noise production. This project aims to dramatically develop our capacity to quieten modern transport, energy and defence technologies through a better understanding of how fluid turbulence creates sound.

New understanding and models for two-phase solar thermal particle receivers. The project aims to provide the new understanding of, and computational design tools for, next generation solar thermal particle receivers and their hybrids. Particle receivers, which heat fine particles in suspension, offer much greater efficiency than current tubular receivers, but are presently unreliable due to the poor understanding of the complex and coupled mechanisms that govern their performance. The results ar ....New understanding and models for two-phase solar thermal particle receivers. The project aims to provide the new understanding of, and computational design tools for, next generation solar thermal particle receivers and their hybrids. Particle receivers, which heat fine particles in suspension, offer much greater efficiency than current tubular receivers, but are presently unreliable due to the poor understanding of the complex and coupled mechanisms that govern their performance. The results are expected to speed up the development and roll-out of these devices, to deliver cost-effective, low-emissions energy technologies for future power generation and thermo-chemical processes. The aims will be met by the parallel application of advanced laser diagnostic measurements and computational fluid dynamics modelling techniques.Read moreRead less
