摘要/Abstract

摘要： 为保证航空燃油储运安全和机场消防安全,设计并搭建航空燃油流淌火试验平台,以航空煤油(JP4)为试验燃料,根据蠕动泵转速选取4种不同泄漏速率,开展航空煤油流淌火试验研究。试验中记录航空煤油流淌火的火焰前沿位置、燃烧面积、蔓延速率等典型特征参数,并对试验过程进行录像,分析典型特征参数的变化。结果显示,航空煤油流淌火的稳定线燃烧速率为3.71×10^-5 m/s,初始蔓延速率随泄漏速率的增加率约5.5 mm/s。航空煤油流淌火的典型特征参数均与泄漏速率正相关。

关键词: 流淌火, 火焰前沿, 燃烧面积, 初始蔓延速率, 蔓延规律

Abstract: An experimental platform was designed and built for aviation fuel spill fires. Experiments were carried out for the sake of ensuring the safety of jet fuel storage and transportation and fire safety in airports. Jet fuel (JP4) was selected as the fuel in the continuous spill fire for four different leaking rates based on the rotation of the peristaltic pump. Parameters were measured, including the flame front location, burning area, spreading rate, as well as the spill fire videos recorded. The variations of the typical characteristic parameters were analyzed according to the experimental phenomena. The results show that there is a stable linear burning rate of 3.71×10^-5 m/s and an increase of 5.5 mm/s for initial spreading rate with the increase of leaking rate for JP4, and that there is a positive correlation between the typical characteristic parameters and the leaking rates.

Key words: spill fire, flame front, burning area, initial spreading rate, spreading characteristics
