Abstract

In order to study the influence of fire location on heat and mass transfer and smoke hazard in the room when a fire occurs, the indoor fire model was constructed by using fire dynamics simulator, and the indoor fire simulation experiments were carried out. Three cases with different fire source locations were set up. After verifying the rationality of the model, the numerical simulation was carried out. The changes of velocity field, temperature field and FED in three cases were discussed.

RESULTS show that in the horizontal direction, the maximum influence of indoor fire passing through the door on the outdoor is 66. 7% of the room's horizontal length, and that when the fire source is located in the geometric center of the room's ground, the time required from the start of fire to the lethality of smoke is the longest, which is 21. 75% more than the shortest scene. © 2019 China Safety Science Journal.
