The aim of this PhD project is to develop advanced technologies for building a millimetre-resolution electrical impedance imaging system operating in high-frequency band between 50 and 200 MHz for monitoring produced water flow in oilfield surface facilities or similar flows in other process industries. Such a system will fill a significant gap in the frequency spectrum of electrical impedance measurement technologies currently in use, which is either in the microwave region of GHz or in a lower frequency region of below a few MHz. The imaging system will draw experience from the current generation of centimetre-resolution electrical tomography systems developed at University of Manchester, aiming to significantly improve spatial resolution and measurement accuracy.
There are two main technical challenges for this PhD project: (1) Designing electronic measurement systems that operate in the required frequency band and (2) Developing an electrical impedance imaging system with high spatial resolution. The project will focus on the technical challenges associated with this specific application. There will be close interactions between the industrial partner and the University of Manchester, and there will be opportunity to be seconded to an industrial research lab to gain experience, and take advantage of their domain knowledge and experimental facilities in developing the measurement concept and a first a working prototype.
The candidate should have a minimum 2.1 honours degree and have capability in electronic circuit design, electromagnetics and maths. After training, he/she should be able to design impedance measuring circuits and data acquisition system, carry out sensor modelling and digital signal processing, and implement image reconstruction by solving the inverse problem. He/she must start before Sept. 2021.
