摘要： 针对油料火灾燃烧特性，基于油料燃烧实验结论，选用湍流燃烧模型、热辐射模型以及烟气模型，利用FLACS 模拟直径0.5 m 的小尺度油池火燃烧和大尺度野外组合式软体油囊油料泄漏起火。结果表明：油池火燃烧最大热辐射通量分布并不以油池中轴线严格对称；野外组合式油囊发生油料泄漏后的流淌火灾燃烧过程中整体自装卸托盘处受到的最大辐射强度高达35 kW/m2，油囊处受到的最大辐射强度约18 kW/m2；火灾发生20 s 后油囊受到的热辐射强度即可达到使油囊熔化的最低能量。

Abstract: According to the combustion characteristics of oil fire, FLACS software was used to simulate the combustion process of small scale 0.5 m oil pool fire and the leakage and fire process of large scale field combined soft oil sac. The results show that: the distribution of maximum heat radiation flux of oil pool fire combustion is not strictly symmetrical with the central axis of oil pool. In the process of flowing fire combustion after oil leakage of the outdoor combined oil sac, the maximum radiation intensity received by the whole self- loading pallet is up to 35 kW/m2, and the maximum radiation intensity received by the oil sac is about 18 kW/m2. 20 seconds after the oil fire occurs, the thermal radiation intensity of the oil sac can reach the minimum energy for oil sac melting.
