报 告 人：劳力云 博士 （Cranfield University，克兰菲尔德大学）
Liyun Lao is a Senior Research Fellow in Energy and Fluid Processes, Energy and Power, Cranfield University. He obtained his Ph.D. in Control Science and Engineering in 1998, MSc in Measurement Sciences in 1986, and BSc in Instrumentation Engineering in 1983, from Zhejiang University, China. After his Ph.D., he worked as a postdoctoral researcher in Institute of Mechanics, Chinese Academy of Sciences in the area of gas/liquid two-phase flows in horizontal pipes. Prior to joining Cranfield University, he was the research associate in the area of two-phase flows in vertical pipes for six years at Imperial College and the University of Cambridge. He is a Member of Institute of Physics.
Dr Lao’s research interests are in the engineering and underlining sciences associated with application areas focusing on the experimental multiphase fluid dynamics and energy processes. His research topics are closely related industrial issues such as flow assurance, phase mixing and separation, and process measurement, monitoring and control. He has pioneered the study of icing in aviation fuel systems since 2010, and established a reputation on this specific but critical topic. By this he won the research projects awarded by industry such as Airbus, Rolls-Royce, and Eaton, and public funding bodies such as EASA and EU FP7. He has also established an international profile in industry-related multiphase channel flows resulting in robust connections with the Oil & Gas industry ranged from the global players such as BP and Schlumberger to SMEs. Since 2012 he has published more than 27 peer reviewed journal papers, most of them were in the highly influential journals. He has been supervising over 50 PhD and MSc students successful to completion as Principal Supervisor. Currently he is also a visiting lecturer at Muscat University, Oman, and the Deputy Director of the Cranfield Energy Informatics MSc course.
Dr Lao is responsible for the management and development of a wide range of fluid dynamic and energy process facilities, including the automated industrial scale plants for multiphase flow loops and other process measurement and high speed imaging equipment. Among them is the 12” horizontal flow loop setup, the largest scale multiphase flow loop in the HE sector in the UK.
This talk would focus on metering of multiphase channel flows in the Oil and Gas industry, where the measurement is highly demanded but poses greatest challenges for the operators and service providers. Over a few decades an increasing effort has been put into this topic and many advancements have been made however the situation is still far from satisfactory. Cranfield has undergone systematic investigations on this topic involving researches ranged from multiphase flows (MPF), sensing technologies, meter performance assessment, and recently play a role in the research toward establishing standardised test facility/flow loop. In this talk, an overview on the MPF at Cranfield will be presented prior to illustration of the Oil and Gas industrial multiphase flow measurement challenges. The activities of sensing technology development and meter performance improvement at Cranfield will also be introduced. Finally the multi-national research project on standardising of MPF meters will be updated.
