Research Areas

Fluid Mechanics and Heat Transfer.

Consulting Activity

Technical advice on fluid flow and heat transfer problems in heat exchange equipment, fluid transport systems, boilers, nuclear reactors, measurement techniques


Professor Kawaji has been teaching and conducting research at the University of Toronto since 1986. He specializes in multiphase flow and heat transfer, covering a wide range of fundamental and applied research topics, and has published over two hundred technical papers. Based on his research experience, he can provide technical advice in the following areas:

  1. Fluid flow analysis: flow rate and pressure drop, pumping, and liquid level
  2. Multiphase flow including gas-liquid and solid-liquid two-phase flows
  3. Thermal problems in heat exchangers and boilers
  4. Nuclear reactor thermal-hydraulics
  5. Boiling heat transfer
  6. Microelectronics cooling using micro heat pipes and micro heat exchangers
  7. Microfluidics
  8. Thermal storage, ice slurry generation and utilization
  9. Advanced measurement techniques: flow visualization, velocity profiles, temperature fields, void fraction
  10. Computational fluid dynamics, free surface simulation using VOF and Level Set methods
  11. Sustainable energy production such as hydrogen production

Professor Kawaji is currently serving on the editorial boards of academic journals, and scientific committees of the International Center for Heat and Mass Transfer and various international conferences. He is a Fellow of the Chemical Institute of Canada and has served on several government advisory committees including the Microgravity Sciences Advisory Committee of the Canadian Space Agency.

Professor Kawaji’s laboratory is equipped with several gas-liquid flow loops including air, water, kerosene, refrigerant and ice slurry. In addition, he has various flow and thermal diagnostics equipment such as a high-speed video camera, infrared thermal imager, UV and green lasers for flow visualization, Mach-Zehnder interferometer, microscopic imaging system, and digital image analysis system. His group has developed several three-dimensional numerical simulation codes and can also run commercial CFD codes such as FLUENT and PHOENICS.
