摘要:
为了探究风速对高层建筑火灾时环境中温度、烟气浓度、CO浓度分布状态的影响,以央视北配楼火灾为模型背景,应用火灾动力学软件FDS,对火灾进行模拟与分析。通过讨论不同风速下火源温度中心、烟气浓度中心、CO浓度中心离着火面距离与高度之间的关系,得到风速一定时各中心的位置与高度之间的变化规律,以及该变化规律与风速之间的关系,风速小于3m/s时各中心位置随风速变化较明显;风速越大,温度、烟气浓度、CO浓度越高,当风速小于2m/s时各值增量随风速增加明显;与其他因素相比,温度对防火间距的影响最大。 更多还原
Abstract:
In order to explore the influence of wind speed on temperature,soot concentration and the concentration distribution of carbon monoxide in high-rise building fires,setting the CCTV North Building Fire as the model background,the fire was simulated and analyzed via the software Fire Dynamics Simulator(FDS).By discussing both the distance between the flame temperature center,flue gas level center,carbon monoxide concentration center and the fire surface,and the distance between the above three and the horizontal plane under the different wind speed,the experiment puts forward the change law between the horizontal plane and the above three centers in a fixed wind,and the relationship between the wind and the change law.Each offset increment is obvious with the wind changes when it is less than 3 meters per second;Meanwhile,the greater the wind speed,the higher the temperature and flue gas concentration as well as carbon monoxide concentration will be,and it is more evident for each offset increment to increase with the wind speed that is less than 2 meters per second;in addition,the effect of temperature,compared to the flue gas concentration and carbon monoxide concentration,is the greatest on the fire prevention span.
