To get the qualitative analysis of the exhaust system during a
fire accident, a further study is very necessary. Moreover, due to
the limit of cost, there is not any dedicated ventilation equipments
during a fire accident in some subway station and the normal ventilation
equipments have to play the role on exhausting smoke and
controlling smoke diffusion. The efficacy of smoke confinement is
not clear when these ventilation equipments were used in a fire.
To solve those questions and study the ventilation system in more
detail during a subway station fire, experiments and numerical
simulation were conducted to analyse the different ventilation
modes and an optimal ventilation mode was proposed. One important
thing to note was that the physical model, being studied, was
not set particular exhaust system and the ventilation system had to
play the role on exhausting smoke during the fire accident.
