摘要
将5个相同的基本空间单元分别按串联式、放射式和走道式进行组合,在相同的火灾场景下使用同一标准火源对各组合空间进行火灾模拟,定量比较其火灾特性指标,包括温度、能见度、CO质量分数,并分析开窗尺寸对各组合空间能见度的影响情况。各组合空间中能见度最先达到危险状态,对人员疏散影响最大。在相同的开窗尺寸下,组合空间能见度指标达到危险状态的时间由大到小依次为串联式、走道式、放射式。
Five identical basic spatial units were assembled in series,radiation and aisle respectively,and the fire in the same scenario using the same standard fire source was simulated to compare the fire characteristics quantitatively,including temperature,visibility and CO mass fraction.The influence of window size on the visibility of each combination space was analyzed.Visibility reaches the dangerous state first in each combination space,which has the greatest impact on evacuation.Under the same window size,the time of reaching the dangerous state of the visibility index in the combined space is in the order of series,aisle and radiation from large to small.
