摘要
FDS模拟地铁枢纽站换乘口火灾,计算不同补风条件下火源上方顶棚不同位置温度分布。将数值模拟结果分别与Alpert和Kuroki提出的经验公式的计算结果进行对比,并在Alpert公式基础上,提出一种包含弗劳德数和经验常数的预测公式。结果表明,该公式相比于已有的经验公式有着更高的预测准确度。
The subway transfer tunnel fire was simulated by FDS,and the temperature distribution on the ceiling above the fire source under different air supply condition was calculated.The simulation result was compared with the empirical formula of Alpert and Kuroki.Based on the Alpert formula,a formula containing Froude number and empirical constant was put forward.Results showed that,the formula has higher prediction accuracy than existing empirical formula.
