- 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.
