Firstly, each participant made a brief self-introduction. Then we entered the expert speech session, in which five experts from many famous universities and research institutions in China were invited to make a keynote report.

Professor Xu Jian'an, Dean of the School of Electromechanical Engineering at Harbin Engineering University, took the lead in his presentation, focusing on the design and optimization of tidal current energy harvesting devices. Professor Xu Jianan, who has rich experience in related technology research and practice, introduced the design principles and key technical points of tidal current energy harvesting devices, and emphasized the challenges and coping strategies encountered in the process of device optimization. By citing several practical cases, he analyzed the technical bottlenecks in the current design and proposed innovative solutions aimed at improving the efficiency and stability of the device.

Immediately after, Prof. He Guanghua from the School of Ocean Engineering, Harbin Institute of Technology (Weihai), as the second speaker, shared his latest research results in the field of ocean engineering. Prof. He firstly emphasized the importance of tidal and wave energy as renewable energy sources, and elaborated on the latest progress made by his research team in the design, modeling and experimental research of tidal and wave energy harvesting devices. His informative and wide-ranging presentation triggered extensive attention and active discussions among the participants.

Prof. Tang Hui from the Department of Mechanical Engineering, Faculty of Engineering, The Hong Kong Polytechnic University discussed the experimental analysis methods of tidal current energy harvesting devices and their application prospects from different perspectives. Focusing on the experimental methods of tidal energy harvesting devices, Prof. Tang discussed in depth the innovativeness and applicability of these methods. He pointed out the limitations of traditional experimental methods in simulating the real marine environment, and in response to these challenges, he shared his team's innovative breakthroughs in related theories and methods, which have effectively improved the accuracy and reliability of experimental results.

Prof. Zhen Liu from the Department of Ocean Engineering, College of Engineering, Ocean University of China, presented cutting-edge research on the oscillating hydrofoil tidal current energy harvesting device. He discussed in depth the experimental variables of the device and the effect of changing the hydrofoil flexibility on the performance of the device. Prof. Liu first outlined the basic working principle of the oscillating hydrofoil tidal current energy harvesting device and emphasized the importance of reasonable selection and control of experimental variables in experimental research. He then focused on the effect of changing hydrofoil flexibility on the performance of the tidal energy harvesting device and discussed the potential application prospects of optimizing hydrofoil flexibility through experiments.

Finally, researcher Cui Lin from the National Center for Ocean Technology made a speech. He systematically analyzed the current status and future trend of the development of tidal energy harvesting technology from the perspective of national policy and general research direction. Researcher Cui reviewed the national policy support and strategic layout in marine energy development in recent years, and pointed out that as an important part of clean and renewable energy, marine energy has become one of the priorities of national energy strategy. His presentation not only clarified the development path of tidal energy harvesting technology for the participants at the policy level, but also provided clear guidance for the future research direction.

After the presentation session, the participants had a warm discussion around the conference theme, and the experts expressed their views and provided valuable suggestions and opinions for the follow-up research of the project. The meeting also attracted many doctoral and master's degree students in related fields of research to listen. They actively participated in the discussion and interacted with the experts, showing strong academic interest and research enthusiasm.

The meeting was successfully concluded after lively discussions and active exchanges among all participants. This meeting not only laid a solid foundation for the smooth progress of the project, but also significantly strengthened the cooperation and communication between universities and research institutions. Through in-depth discussions and experience sharing among experts, the core research direction of the joint research project was clarified, and clear guidance was provided for the subsequent research plans on the construction of oscillating hydrofoil model, experimental design, and optimization methods. Meanwhile, the interactions among the participants promoted the opportunities for interdisciplinary cooperation and laid a good foundation for future research and applications, and injected new momentum into the development of China's ocean energy technology.
