CNERC-Rail Research Seminar: Prof. You-He Zhou from Lanzhou University and Prof. Xiao-Jing Zheng from Xidian University, China

On the morning of 4 March 2026, the National Rail Transit Electrification and Automation Engineering Technology Research Centre (Hong Kong Branch) (CNERC-Rail) at PolyU hosted an academic seminar entitled “Challenges and Progress in Superconducting Multi-field Coupled Mechanics under Extreme Environments.” The seminar was held in Room Z414 at PolyU and featured Prof. You-He Zhou, Academician of the Chinese Academy of Sciences from Lanzhou University, and Prof. Xiao-Jing Zheng, Academician of the Chinese Academy of Sciences from Xidian University, as the invited speakers. During the seminar, Prof. Zhou introduced the research background and key scientific challenges associated with superconducting multi-field coupled mechanics under extreme environments. He highlighted the team's recent advances in the theoretical development of multi-field coupled superconducting solid mechanics, the establishment of experimental research platforms, and the development of effective solution methods for strongly nonlinear multi-field coupled mechanical problems. Prof. Zheng then focused on gas–solid two-phase turbulence in sandstorms and presented research on field observations and wind-tunnel investigations of sandstorm dynamics. She introduced long-term observational studies based on the Qingtu Lake Observation Array and discussed the statistical characteristics of turbulent structures in sandstorm flows as well as the interactions among turbulent motions at different scales. The presentation also addressed the applications of these findings in understanding wind–sand disaster mechanisms and improving numerical simulation approaches.

CNERC-Rail Research Seminar: Prof. Ming-Feng Huang from Guangxi University, China

On the afternoon of 10 February 2026, the National Rail Transit Electrification and Automation Engineering Technology Research Centre (Hong Kong Branch) (CNERC-Rail) at The Hong Kong Polytechnic University successfully hosted an academic seminar entitled “Physical Simulation and Turbulence Numerical Generation of Urban Typhoon Wind Fields.” The seminar featured Prof. Ming-Feng Huang from Guangxi University as the invited speaker. During the seminar, Prof. Huang systematically introduced recent advances in the multiscale numerical simulation of urban typhoon wind fields, with a particular focus on the application of the WRF–LES coupled framework under real typhoon conditions and the analysis of wind pressure characteristics on tall buildings. Using Super Typhoon Mangkhut as a case study, he discussed the differences in wind fields between damaged and undamaged regions and examined the non-Gaussian characteristics of wind pressure. The reliability of the numerical framework was further validated through wind tunnel experiments. In addition, Prof. Huang presented a GPU-accelerated three-dimensional turbulent wind field generation method, which significantly improves the computational efficiency of turbulence generation in WRF–LES simulations. The seminar stimulated active discussions among faculty members and students, providing a valuable platform for academic exchange in urban wind environment modelling and typhoon-resilient design, and was well received by the participants.
