2月26日上午9点30分,应水力学与山区河流开发保护国家重点实验室邀请,新加坡国立大学流体机械工程系KhooBoo Cheong教授来我院进行学术讲座。B.C. Khoo教授以“Dynamics of Supercavitating Flow Perturbed by Pressure Wave and Flow Induced Noise Propagationin Supercavitating Vehicles”为题,与师生们分享了他最新的空化流研究成果。

B.C. Khoo教授介绍了考虑液体可压缩性影响条件下的空化流数学模型,并在此基础上详细阐释了外界压力波扰动条件下的空化流动力学特性,讲解了如何利用Boundary Integral Equation (BIE)的计算方法来研究空化流的噪声问题,并分析了空化流噪音的诱因,即:由于超空化周围的湍流压力波动引起的噪声、汽-水界面处的小尺度压力波动诱发的噪音,以及压力波动导致的空化溃灭对壁面的冲击噪音。这些空化流的研究方法对于我们细观水力学中的空蚀机理研究和空化流研究具有重要的借鉴意义。

讲座结束后,水力学与山区河流开发保护国家重点实验室林鹏智教授总结发言,对B.C. Khoo教授的精彩报告表示感谢。B.C. Khoo教授用简洁生动的语言回答了在场学生的很多问题,在学生们热烈的掌声中结束了这次学术报告。



B.C. Khoo教授简介:

BC Khoo graduated from the University of Cambridge with a BA (Honours, 1st Class with Distinction). In 1984, he obtained his MEng from the NUS and followed by PhD from MIT in 1989. He joined NUS in 1989. From 1998 to 1999, he was seconded to the Institute of High Performance Computing (IHPC, Singapore) and served as the deputy Director and Director of Research. In 1999, BC returned to NUS and spent time at the SMA-I (Singapore MIT Alliance I) as the co-Chair of High Performance Computation for Engineered Systems Program till 2004. In the period 2005-2013, under the SMA-II, he was appointed as the co-Chair of Computational Engineering Program. In 2011-2012, BC was appointed the Director of Research, Temasek Laboratories, NUS. Since 2012, he has been the Director, Temasek Laboratories.  

BC Khoo serves on numerous organizing and advisory committees for International Conferences/Symposiums held in USA, China, India, Singapore, Malaysia, Indonesia and others. He is a member of the Steering Committee, HPC (High Performance Computing) Asia. He has received a Defence Technology Team Prize (1998, Singapore) and the prestigious Royal Aeronautical Prize (1980, UK). Among other numerous and academic and professional duties, he is the Associate Editor of Communications in Computational Physics (CiCP) and Advances in Applied Mathematics and Mechanics (AAMM), and is on the Editorial Board of American Journal of Heat and Mass Transfer, Ocean Systems Engineering (IJOSE), International Journal of Intelligent Unmanned Systems (IJIUS), The Open Mechanical Engineering Journal (OME) and The Open Ocean Engineering Journal.

BC has published over 360 international journal papers, and over 360 papers at international conferences/symposiums. He has presented at over 115 plenary/keynote/invited talks at international conferences/symposiums/meetings.
