About the Project

We are seeking an enthusiastic PhD student to work with us on this project within the Applied Optics and Photonics research group in the Institute of Photonics and Quantum Sciences under the lead of Dr Robert Maier, in collaboration with Prof. Duncan Hand and Drs Jon Shephard and Bill MacPherson.

This project aims to develop embedded fibre optics sensor technology for temperature and strain monitoring in gas turbine components using regenerated fibre Bragg gratings and additive layer manufacturing technology.

Embedded sensors will permit the operation of turbines at higher temperatures and this will dramatically improve efficiency and safe operation of such plant.

This is a challenging and interdisciplinary research project, at the interface between physics and engineering which includes aspects of fibre optic sensing, metallurgy and additively layer manufacturing technologies.

Introduction:

The project aims to increase the operational efficiency of modern gas turbines by providing integrated sensing technology operating at high temperatures. Currently no long term monitoring technology exist for this task.
Fibre optic sensing based on fused silica fibres and ‘regenerated fibre Bragg gratings show great promise as high temperature compatible sensing components up to 1000 to 1200 °C. Embedding of such sensors by Additive layer manufacturing (ALM) will be investigated.

This is a collaborative project with 9 other European partners from industry and academia spread across Europe (UK, Italy, Switzerland, Germany, France, Ukraine and Belarus). Research by our partners range from improved materials to increase the resistivity of components to oxidation, to the development of Direct Metal Deposition (DMD) cladding techniques.

This is highly applied interdisciplinary research at the interface between engineering and physics, where a wide range of physical, mechanical and metallurgical phenomena need to be investigated to facilitate the end goal of an optical sensor for operation at such high temperatures.

The research is very hands on and involves a wide range of disciplines and technologies ranging from fibre optics, optical metrology, computational modelling, to laser material processing, manufacturing technologies and material sciences. Data analysis, material characterisation, microscopy and NDT analysis techniques will also be used to complement the research.

Reporting of results in quarterly technical project meetings by written reports and oral presentations is essential. You will be working as part of an established research group with a broad portfolio of research interests in pure and applied science and engineering.



Funding Notes

A full tax free stipend of minimum £13600, and all fees paid is available for applicants from the UK and EU.
The studentship is available from start of academic year 2013/14, however an early entry is also possible.

Unfortunately, applicants from outside of the EU cannot receive any funding of fees or stipend and need to be fully self supported.
