Fire Temperature Distribution in Vertical Shaft of High-rise Building Based on Fire Safety
Through the simulation of fire dynamics,the effects of different heat release rates and fire sources in different areas on the temperature in the shaft are analyzed.The results show that the higher the heat release rate of the fire source,the higher the temperature in the shaft.Under the same heat release rate of the fire source,the temperature is higher when the fire source is located near the wall of the room than when the fire source is located in the center of the room.Compared with the fire source located in the center of the room,when the fire source is located near the wall,the fire source releases more heat.With the increase of the building height,the temperature in the shaft gradually decreases,and the corresponding temperature difference decreases.In the case of a fire in a high-rise building,it is recommended that the smoke exhaust design in the front room of the stairs be directly discharged to the outside,which is conducive to the emission of smoke and the evacuation of personnel,when the shaft is connected with the outer corridor.
