A predictive tool for low-emission gas turbine combustors. This project aims to develop a powerful tool for prediction of combustion noise using high-fidelity simulations. Combustion-generated sound is a major inhibitor to the development of low-emission, highly-efficient gas turbines as it can initiate "thermoacoustic instability", leading to engine failure in extreme cases. This project will lead to the advancement of fast start-up, low-emission, gas turbines which can complement renewable en ....A predictive tool for low-emission gas turbine combustors.

Advanced multivariable nonlinear control methodology for matrix converters. The aim of this project is to explore a specific multivariable nonlinear control design problem. Motivation for the project arises from the control of Matrix Converters. Matrix Converters are considered one of the key enabling technologies for the electric transport of the future. However, their penetration into practice has fallen short of their promise. This is, in part, due to the associated control design problem whi ....Advanced multivariable nonlinear control methodology for matrix converters. The aim of this project is to explore a specific multivariable nonlinear control design problem. Motivation for the project arises from the control of Matrix Converters. Matrix Converters are considered one of the key enabling technologies for the electric transport of the future. However, their penetration into practice has fallen short of their promise. This is, in part, due to the associated control design problem which is extremely difficult involving coupled nonlinear dynamics and under-actuation. We plan to address these problems by using modern control system design methods. Our specific goal is to achieve a provably stable, closed loop control system whose performance is independent of unmeasured disturbances and model errors.Read moreRead less

Lifting the Veil on Turbulent Convective Heat Transfer over Rough Surfaces. By understanding the influence of surface roughness on convective heat transfer, this project intends to reduce the unwanted heating and energy losses associated with surface roughness in gas and steam turbines used in power generation and transportation. The surface roughness that results from extended operation of gas and steam turbines can significantly increase the heating of their surfaces, increasing fuel consumpti ....Lifting the Veil on Turbulent Convective Heat Transfer over Rough Surfaces. By understanding the influence of surface roughness on convective heat transfer, this project intends to reduce the unwanted heating and energy losses associated with surface roughness in gas and steam turbines used in power generation and transportation. The surface roughness that results from extended operation of gas and steam turbines can significantly increase the heating of their surfaces, increasing fuel consumption and greenhouse gas emissions, and reducing operational life. Improvements would allow turbines to operate at higher inlet temperatures which will increase their efficiency and reduce fuel use, environmental emissions and maintenance costs.Read moreRead less
Geometry of wall-turbulence and its potential to advance scalable models. This project aims to unravel the connections between the statistical geometry of wall-turbulence and the dynamical interactions of its instantaneous motions. Predicting the complex behaviour of turbulent fluid flow over surfaces in relative motion is central to atmospheric modelling for climate and agriculture, and reducing the environmental effect of fossil fuel usage. Wall-turbulence statistics organise according to a pr ....Geometry of wall-turbulence and its potential to advance scalable models. This project aims to unravel the connections between the statistical geometry of wall-turbulence and the dynamical interactions of its instantaneous motions. Predicting the complex behaviour of turbulent fluid flow over surfaces in relative motion is central to atmospheric modelling for climate and agriculture, and reducing the environmental effect of fossil fuel usage. Wall-turbulence statistics organise according to a predictable geometric structure, and the notorious complexity of turbulent wall-flow dynamics could be clarified through its inherent geometry. This project expects to construct a basis for predicting engineering and atmospheric wall-flows, which would enhance atmospheric flow prediction, reduce energy consumption and further environmental sustainability.Read moreRead less
Growing a multi-scale internal structure: new wrought metals for energy conservation. This research aims to reduce the weight of wrought metal parts so that transport and machinery will use less energy. It will establish how to grow novel multi-scale internal structures and will thereby pioneer a new class of metals that display superior properties.
The Transitional and Turbulent Structure of Rotating Disk Boundary Layers. Design optimization in areas of energy, materials processing, manufacturing and aerodynamics often depends on fluid flows adjacent to surfaces (wall-flows), and many such flows are three-dimensional (3-D). At present, 3-D wall-flows are poorly understood, and thus we aim to provide the first comprehensive study of the prototypical 3-D wall-flow on a rotating disk. Experiments in a bespoke facility will cover the importan ....The Transitional and Turbulent Structure of Rotating Disk Boundary Layers.

At present, 3-D wall-flows are poorly understood, and thus we aim to provide the first comprehensive study of the prototypical 3-D wall-flow on a rotating disk. Experiments in a bespoke facility will cover the important flow regimes (transitional and turbulent), and novel sensors will quantify the detailed 3-D flow structure. By clarifying critical instability scenarios and revealing turbulent flow scaling structure, this project will fundamentally advance physical understanding and analytical and computational models of 3-D wall-flowsRead moreRead less

The goal is to dramatically reduce friction between moving mechanical parts, hence increasing energy efficiency in machines and reducing global greenhouse gas emissions. We will design and test these new friction modifiers by a combination of theoretical and computational methods based in statistical mechanics and nonequilibrium molecular dynamics and directly compare results with experimental measurements. Our investigations will pave the way to develop new cost-effective friction modifiers without the need for traditional and costly trial and error laboratory based experimentation.Read moreRead less
