An Experimental Study Of Ejected Flames Of A High-Rise Building - Effects Of Depth Of Balcony On Ejected Flames

The aim of this study is to investigate the effects of depth of balcony on ejected flames from opening of a fire room. For this aim, an experimental study was done using a 1/7 scale model of seven-storey high-rise apartment building. Variation of temperature in the fire room, that of temperature along trajectories of ejected hot air currents, and that of length and angle of ejected flames were measured and analysed. Temperature in the fire room with balconies was higher than that without balconies. Temperature along trajectory with balconies decreases more rapidly than that without balconies. Horizontal length of ejected flames was independent of depth of a balcony. Vertical length, length, and angle of ejected flame decreased as depth increased.
