Abstract
Smoke movement during a fire in subway tunnel was conducted in this study, when the heat release rate was 7.5 MW. The smoke temperature, smoke concentration and smoke velocity were also analyzed, respectively. If we recognize that the fire is the center, the temperature of the ceiling jet is almost symmetrically distributed. When the fire is in the stable combustion stage, the smoke concentration is high at the closed end of the subway tunnel. Because the plume was limited by the wall, the hot gases will move back after flow along the wall. Therefore, an obvious eddy will be produced. Meanwhile, we can see that the smoke velocity close the ground was also increased.
