Two ME PhD students, Liang Yu and Liu Lili won the Student Competition Awards in the 32nd International Symposium on Shock Waves (ISSW32) held at the Faculty of Engineering, National University of Singapore in Singapore on 14-19 July 2019.
Since the inception of the International Symposium on Shock Wave (ISSW) in 1957, ISSW has served as authoritative platforms for the international scientific community to meet and exchange ideas on the study of shock wave and blast wave related phenomena and their applications. ISSW32 is a continuation in the series of biannual international symposia that have been held throughout the world. It had over 400 participants, including more than 370 overseas delegates. Student authors were encouraged to participate in the Student Competition. Winners were selected based on the best oral and poster presentations.
Liang Yu and Liu Lili are both devoted to Richtmyer-Meshkov instability (RMI) investigation. RMI plays a crucial part in promoting the supersonic combustion efficiency but impeding the ignition in the Inertial Confinement Fusion. Therefore, it is significant to investigate how to improve or suppress RMI developments. Liang Yu reported “Evolution of an air/SF6/air Finite-thickness Fluid Layer Impacted by Shock Wave” and Liu Lili presented “Richtmyer-Meshkov Instability on Dual-mode Interface Impacted by Shock Wave”. Both of them concisely explained the interface coupling as well as compressibility effects on the fluid layer evolutions and the mode-competition effects on the multi-mode interface evolutions. The judging panel acclaimed their presentations, and each received an award of USD250.
Both research study is under the supervision of Prof. Chih-yung Wen and affiliated to the High-speed Thermo-fluid and MAV/UAV Laboratory, Department of Mechanical Engineering, The Hong Kong Polytechnic University.
