Dr Ooi Kim Tiow is a Professor in the School of Mechanical & Aerospace Engineering. He received BEng in 1986 and Ph.D. in 1989, both in Mechanical Engineering from University of Strathclyde, Scotland, U.K. His research areas are in areas related to studies on refrigeration systems and components design, heat transfer and fluid flow. He holds several patents in compressor designs and some of the designs won awards locally and internationally. Dr Ooi is widely consulted by industry both locally and internationally. He also sits in advisory committees in several international conferences on refrigeration compressors and/or their systems.

  • Interest:
    New highly energy efficient refrigeration compressor design, heat transfer and fluids flow.
  • Projects:
    Novel Refrigeration Compressors - Expander-compressor unit
    We have developed a novel highly energy efficient expander–compressor unit called cross vane expander compressor (CVEC) which significantly improves energy efficiency of refrigeration systems. This new invention recovers the expansion energy to reduce the net energy input into the refrigeration systems without noticeable cost increase. Such a design is best suited for high pressure differential refrigeration systems such as those when using CO2 as the refrigerant.
    [Energy Systems Laboratory, Thermo-Fluid & Energy]
    Other new compressor designs such as lubricant free and drive-hub integrated compressors are also being invented and studied.

    Enhanced Microchannel Heat Transfer in Macro Geometry
    Microchannels are known to have very high heat transfer effects, but it comes with a high manufacturing cost and large pressure drop. In this project, the microchannel heat transfer effects are duplicated in macro channels thus solving the cost issues and at the same time lower the significant pressure drop.
