    The Department of Mechanics and Engineering Sciences invites alumnus Quan Wang to give a lecture on ocean energy collection

  • Recently, the "Wang Ren Mechanics Lecture" Series organized by the Department of Mechanics and Engineering Sciences (MES) invited renowned alumnus Prof. Quan Wang to give a lecture. The lecture was chaired by Prof. Zuoli Xiao, Deputy Director of MES. Professors Jianxiang Wang, Dajun Wang, Minzhong Wang, Zhuping Huang, Yueting Xu, Huiling Duan, Pu Chen, Yueguang Wei, Jianping Wang, Faxin Li, Xin Yi, Xiaoding Wei and more than 100 graduate students attended the lecture. Other university scholars and students were also attracted to the event.

    Professor Quan Wang graduated from the Department of Mechanics, Zhejiang University in 1988. He studied at the Department of Mechanics, Peking University from 1988 to 1994 and received master's and doctor's degrees supervised by Prof. Dajun Wang. Having taught at the National University of Singapore, the University of Central Florida, and the University of Manitoba, Canada, Professor Wang is now Chair Professor of Civil Engineering and Architecture at City University of Hong Kong. He was elected to the Canadian Academy of Engineering in 2015, to the Royal Canadian Academy of Sciences in 2016. His research fields are the theory and application of structural health monitoring and maintenance, nanotechnology and energy harvesting.


    Professor Quan Wang gives the lecture

    In his lecture, Prof. Wang pointed out that in recent years, piezoelectric materials have been tried to be used to harvest energy from waves. He introduced the basic process of harvesting energy from the waves. The world's ocean wave energy in deep water is estimated to be over 1TW, almost equal to the world's energy consumption. Its great potential can be an important way for man to obtain the necessary energy resources.

    Prof. Wang then introduced the current technology of wave energy conversion device, the mechanisms and the challenges. He reviewed three energy conversion technologies - the electrostatic, electromagnetic and piezoelectric technology. And through the comparison of power generation capacity, transmission efficiency, structure installation and economic cost of these three technologies, the characteristics and advantages of piezoelectric energy conversion technology are expounded, especially on "the application of piezoelectric material in engineering structure" and "piezoelectric material in the application of waves energy collection”.

    Wang introduced the work of his research team in using intelligent materials in the energy harvest from the waves, and discussed the potential of piezoelectric generators in large-scale energy collection such as high-rise buildings and vehicle suspension systems. In addition, Professor Wang also briefly described applications of the intelligent material in the fault monitoring and repair in engineering structure.

    Through the lecture, the audience gained a more in-depth understanding on the relevant theory and technology development of the wave energy collection.




    The report attracted many teachers and students

    After the lecture, the teachers and students presented questions to Professor Wang, and had a warm exchange and discussion on the contents of the report. Then Professor Wang recalled his study experiences in the Department of Mechanics, and paid attributes to his then-supervisor Professor Dajun Wang, as well as his then-teachers Professor Zhuping Huang, Minzhong Wang and other teachers.
