摘要

本文采用fire Dynamics Simulator, version 6 (FDS6)软件,采用4种不同的简单几何形状对大型重型货车(HGV)隧道火灾实验进行模拟,研究不同燃料包形状对隧道火灾实验的影响。模拟还研究了当一个大目标放置在燃料包的下游时对温度分布的影响。火焰扩展、温度分布和气体浓度的预测结果与实验数据进行了比较。几何形状的使用在充分发展的火焰阶段引起火焰延伸长度的显著差异。当火后存在一个大目标时,使用不同燃料形状引起的温度预测变化是微不足道的,然而,如果目标被省略,特别是在完全开发阶段,情况就不是这样了。

Assessing the influence of fuel geometrical shape on fire dynamics simulator (FDS) predictions for a large-scale heavy goods vehicle tunnel fire experiment

This paper uses four different simple geometrical shapes to simulate a large-scale heavy goods vehicle (HGV) tunnel fire experiment using Fire Dynamics Simulator, version 6 (FDS6) in order to investigate the influence of using different fuel package shapes. Simulations also investigate the influence on temperature profiles when a large target is placed downstream of the fuel package. Predictions of flame extension, temperature profiles and gas species concentrations are compared with the experimental data. The use of the geometrical shapes causes significant differences in flame extension lengths during the fully developed fire phase. The variation in temperature predictions caused by using the different fuel shapes are insignificant when a large target is present behind the fire, however this is not the case if the target is omitted especially during the fully developed phase.
