Research Areas

Area 1: Fire Modelling

  • Research effort was directed on the mathematical modelling of fire for over 25 years.
  • A fire field model using general technique in computational fluid dynamics and heat transfer was developed.
  • The fire-induced air flow field in an enclosure at the pre-flashover stage can be successfully simulated.
  • The smoke movement pattern can be predicted accordingly.
  • The application to design longitudinal ventilation systems for tunnels and smoke extraction systems for atria has been reported.
  • Detailed combustion chemistry is studied for upgrading the model to the post-flashover stage. 
  • Fire chemistry in burning poly(methyl methacrylate), poly(vinyl chloride) and polyurethane were studied. 
  • The development of a new fire model is in progress with combustion, turbulence and radiation. 
  • Different fire zone models in the literature were evaluated.
  • Flashover criteria based on chaotic theory and physics of buoyancy-induced turbulence were explored.
  • Symbolic mathematics was applied to develop new models.  Verification and validation of fire models with large-scale experimental studies to carry out.
