MHI CommNetS seminar

Speaker: Dr. Wuqiang Yang, University of Manchester, UK

Talk Title: Electrical capacitance tomography - making unmeasurable be measurable and controllable

Series: CommNetS

Abstract: In industry, it is difficult to measure some processes, such as multiphase flows in pipelines and gas/solids fluidised beds. In other words, some industrial processes are still unmeasurable and hence uncontrollable. To measure such difficult processes, industrial tomography techniques have been developed. Among various modalities, electrical capacitance tomography (ECT) is the most mature. ECT is based on measuring capacitance from a multiple electrode sensor, which contains multiple dielectric materials, and reconstructing permittivity distribution, from which important parameters can be derived, such as solids' distribution and concentration in a fluidised bed. ECT has been used to measure some processes, which otherwise cannot be measured, and hence makes it possible to control those processes. During this talk, the principle of ECT will be introduced and some challenging industrial applications will be discussed, together with a live demonstration of an AC-based ECT system.

Biography: Wuqiang Yang is a Fellow of the IEEE, Fellow of the Institution of Engineering and Technology (formerly IEE), and Fellow of the Institute of Measurement and Control. He received his BEng, MSc and PhD degrees from Tsinghua University in Beijing. Since 1991, he has been with The University of Manchester (formerly UMIST) in the UK. His main research interests include industrial tomography, electrical capacitance tomography (ECT), image reconstruction and multiphase measurement. The AC-based ECT systems he developed are being used by many universities, research organisations and companies, such as Schlumberger, Rolls Royce and Chinese Academy of Sciences. He has published over 400 papers, is a referee for over 50 journals, Associate Editor of IEEE TIM, editorial board member of 6 journals, guest editor of many journal special issues and visiting professor at several other universities. He is a key organiser of IEEE Int. Conference on Imaging Systems and Techniques.
