【摘要】 针对室内商业街这一特殊建筑结构,使用FDS火灾模拟软件进行三维数值模拟研究商业街内部火灾烟气输运,分别对三种不同排烟工况进行了详细的计算,重点研究了室内商业街拱顶蓄烟能力和机械排烟工况下烟气的输运状况,得到了对防火设计和工程应用有价值的结论。更多还原

【Abstract】 A numerical study of some fire scenarios on a large indoor street was described. To study its smoke movement, the detail computations were determined at three working conditions. The ability of smoke tolerance and smoke movement under the condition of mechanical smoke exhaust were mainly studied. By comparing the results of different working conditions, the conclusions of fire protect design and engineering were made.更多还原
