About the position

A post-doctoral researcher position is available at the Department of Energy and Process Engineering, in the Fluids Mechanics group.

The appointment has a duration of 3 years and is financed through a European Research Council starting grant (TAIAC), which is aimed at radically improving our understanding of combustion instabilities in annular combustion systems.

The Head of the Department is Professor Terese Løvås. The position’s supervision is by Associate Professor Nicholas Worth.

Job description

It is well known that low emission combustion concepts for aeroengines and gas turbines for power generation are prone to combustion instabilities. These instabilities cause large amplitude pressure oscillations that can drastically reduce the operable range or compromise the structural integrity of gas turbines. Within the last few years laboratory­scale annular combustors capable of reproducing thermoacoustic oscillations found in full scale engines have been developed, giving us unprecedented access to information about their nature. The current research project is aimed at improving our fundamental understanding of the combustion dynamics which occur during self-excited instabilities in laboratory scale annular combustors.

The current research project is aimed at improving our fundamental understanding of self-excited combustion instabilities in both an atmospheric and pressurised laboratory scale annular combustor. In particular, the pressurised annular combustion facility has been developed during the TAIAC project and provides a unique opportunity to study such instabilities in a configuration with realistic acoustic boundary conditions. The position will involve designing and running combustion experiments, and conducting experimental measurements using state-of-the-art techniques, such as high-speed OH* imaging and OH-PLIF. These measurements will be aimed at developing our understanding of the flame structure and dynamic response during thermoacoustic instability, with the ultimate aim of helping to reduce gas turbine emissions.
