摘要
以较为精确的场模拟为参照,对于运用双区域模拟计算出的大空间建筑火灾室内烟气温度与时间的关系曲线进行修正。通过比较计算结果得出,此修正方法提高了计算精度,并在一定程度上扩大了双区域模型计算方法的适用范围和可计算时间。
Revises the temperature-time curve of large space building fires, which is calculated by two-zone fire model. The examples are calculated comparing with field fire model, which is more precise and complicated. The results indicate, that the revision can improve the precision of two-zone fire model effectively, and broaden the limit of the model to a certain extent.(
