Abstract :
To understand the characteristics of smoke spreading of fires in a flat underground, experimental and numerical researches were conducted. By comparing the results of the experiment and simulations, the conclusions were drawn that when the maximum heat release rate (HRR) is higher than 480 kW in the flat-space building, it only took 10 s to reach a distance 15 m from the fire source, and 100 s to fill up the 964 m3 volume of the upper part above 2.0 m height of the flat space, which was mainly due to the heat release rate (HRR). However, the HRR did not have obvious effect on the speed of the smoke propagation along the ceiling. Moreover, the temperature stratified vertically in the distance far from the fire source.
