From January 9 to 12, the 1st China-Japan-Korea Symposium on Thermal and Fluid Engineering was successfully held in Hangzhou, Zhejiang Province. The event was jointly organized by the Hangzhou International Innovation Institute of Beihang University (hereinafter referred to as H3I) and the Key Laboratory of Fluid Mechanics, Ministry of Education, based at Beihang University.

Thermal and fluid engineering, as a core interdisciplinary field bridging fundamental science and engineering applications, governs the transfer and utilization of energy, mass, and momentum in various systems. It is widely applied in areas such as aerospace propulsion, micro electronics thermal management, low-carbon industry, and deep-sea resource development. Amid the global acceleration toward carbon neutrality and intelligent manufacturing, this discipline has become a critical pillar for overcoming technological bottlenecks in strategic industries.

This symposium served as an extension and upgrade of the 5th China-Korea Symposium on Thermal and Fluid Engineering held in 2019. For the first time, Japanese scholars were invited to participate, forming a new pattern of collaborative exchange among researchers in the field of thermal and fluid engineering from the three countries. The symposium was co-chaired by Professor Pan Chong from Beihang University and Professor Kyung Chun Kim, Academician of the National Academy of Engineering of Korea, from Pusan National University, with the guidance of the Chinese Society of Theoretical and Applied Mechanics.

The opening ceremony took place on the morning of January 10. Professor Kyung Chun Kim presided over the ceremony and delivered an opening speech, introducing the overview of the symposium. Professor Pan Chong delivered a welcome speech, extending a warm welcome to all participants.

Centering on the global context of carbon neutrality, intelligent manufacturing, and efficient energy utilization, the symposium focused on key topics such as complex multiphase flow modeling under extreme conditions, the integration of artificial intelligence and fluid dynamics, and interdisciplinary collaborative optimization. It aimed to address technical bottlenecks hindering the transformation of theoretical breakthroughs into industrial applications. The event brought together over 40 top experts in thermal and fluid engineering from China, Japan, and South Korea. They delivered a series of insightful keynote speeches covering a wide range of topics, from microscopic bubble dynamics to macroscopic aerospace applications, including bubble dynamics theory, low-Mach number flow theory, turbulent structure and interaction, advanced flow field measurement technology, intelligent flow control, and multiphase flow and thermal management technology. More than 60 domestic and international graduate students from H3I attended the speeches and engaged in discussions with the experts.

The symposium showcased the latest research achievements in thermal and fluid engineering and related fields. It provided a platform for scholars from China, Japan, and South Korea to explore opportunities and challenges for the development of thermal and fluid engineering in the context of rapid advancements in intelligent technologies. The event fostered academic exchanges, strengthened the foundation for long-term international collaboration in the field, and laid a solid groundwork for accelerating regional technological innovation and jointly addressing industrial and societal challenges.
