Mr Fan Jianhui, a PhD student under the supervision of Prof. Chih-yung WEN and Dr Jiaao HAO, won the Student Paper Competition Award (out of 12 winners in total) at the 34th International Symposium on Shock Wave (ISSW34) held in Daegu, South Korea, from 16-21 July, 2023. The competition provided an exciting opportunity for student authors to showcase their research.
Jianhui’s winning paper, entitled "Coexistence of different mechanisms underlying the dynamics of supersonic turbulent flow over a compression ramp," sheds light on the unsteady dynamics of shock-wave/turbulent boundary-layer interaction using dynamic mode decomposition, linear and nonlinear disambiguation optimization, and global stability analysis. The study explores different mechanisms for the dynamics of shock wave/supersonic turbulent boundary layer interactions, including Görtler instability, global instability, and convective instability. By examining the connections between the unsteady motions and the revealed modes, the study confirms the coexistence of these mechanisms in the present flow.
This achievement is a testament to the research capability of Jianhui and the excellent guidance provided by Prof. Wen and Dr Hao. Congratulations!
