Prof. KHOO Boo Cheong
National University of Singapore, Singapore

Director, Teamsek Laboratories, National University of Singapore (NUS)

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, Taiwan, 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.

In research, BC ‘s interest are in:
(i) Fluid-structure interaction
(ii) Underwater shock and bubble dynamics
(iii) Compressible/Incompressible multi-medium flow

He is the PI of numerous externally funded projects including those from the Defense agencies like ONR/ONR Global and MINDEF (Singapore) to simulate/study the dynamics of underwater explosion bubble(s), flow supercavitation and detonation physics. His work on water circulation and transport across the turbulent air-sea interface has received funding from the then BP International for predicting the effects of accidental chemical spills. Qatar NRF has funded study on internal sloshing coupled to external wave hydrodynamics of (large) LNG carrier.

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.

Speech Title: "Study of Sub- and Supersonic Flow Control with Dielectric Barrier Discharge Plasma Actuator"

The nanosecond (ns) dielectric barrier discharge (DBD) plasma actuator is driven by pulse voltage with pulse duration ranging from tens of to hundreds of nanoseconds. The relatively quick plasma discharge causes the conversion of part of electrical energy into near surface gas heating within the discharge volume in a short time period of less than 1 s. As a result, the temperature and pressure in the actuator region increase appreciably, which in turn causes the generation of a micro shock wave. The ns DBD plasma actuator has proved to be an effective actuation technique in many aerodynamic systems, and actually functions via the Joule heating effect1. By contrast, the alternating current (ac) plasma actuator achieved the control authority through the discharge induced flow jet. In the current study, a combined numerical and experimental study of flow separation control over a NACA 0015 airfoil with ns and ac plasma actuators is conducted for a comparison of performance between two types of devices. It is found that for the airfoil leading edge separation control in the subsonic regime, the nanosecond discharge induced residual heat causes the generation of spanwise vortices and finally makes the separated flow being reattached, whereas the shock wave contributes little to control authority. The advection of residual temperature with external flow offers a nanosecond plasma actuator a lot of flexibility to extend its influence region. Therefore, under certain situations, the ns DBD is superior to its ac counterpart, whose influence region is limited to the discharge region. In addition, a concept study of the supersonic flow control with the nanosecond DBD is performed by means of numerical simulation.
