RESEARCH EXPERIENCE
1998-2002 Postdoctoral Research Fellow (Level B): Monash University
- Laboratory Manager: Responsible for the development, organization and maintenance of laboratory equipment. Assist with menotoring of postgraduate students.
- 3D Oscillating Foil Propulsion: Designed a small pitching and heaving airfoil system to study the bio-fluid mechanics of swimming with finite-span foils.
- 3D PIV: Development of a holographic particle image velocimetry system and stereoscopic scanner system. Also working with Prof. Pilar Arroyo (Universidad de Zaragoza, Spain) on the study of holographic interferometry systems.
- Taylor-Couette Flow: Constructing an apparatus to study the effects of rapid accelerations on Taylor-Couette flows; working in collaboration with Prof. T.T. Lim of the National University of Singapore.
- Water Tunnel Design: Built a small 100x100 mm2 water tunnel.
- Theory: Applied similarity and dimensional analysis techniques to find analytical and numerical solutions for compressible free vortex flow.
- Computations: Developed a set of non-reflecting boundary conditions to model the propagation of axisymmetric acoustic waves in a computational domain of cylindrical geometry.
- Experiments: Used shadowgraph and schlieren optical techniques to study the formation of compressible vortices by shock diffraction around an airfoil in the test section of a shock tube. Also used these techniques to study the production of sound waves in compressible vortex/airfoil interaction.
- 1988-1990 Space Systems Lab: Designed, constructed and tested electrical and mechanical subsystems for underwater robots.
- 1988 VTOL Technology Lab: Worked with a graduate student on a theoretical design study of an active control system for the alleviating gust-induced bending modes of a tilt-rotor aircraft's propeller blades.
- 1986-1987 Plasma Fusion Center: Assisted a graduate student with an experimental study of the fracture of composite materials at cryogenic temperatures.
