摘要 以燃料电池客船“Water-Go-Round”号为对象,利用FLUENT软件模拟燃料电池客船舱内管道发生氢气泄漏并引发爆炸的情况,研究不同舱室氢气点火爆炸事故的影响规律。结果表明:可燃氢气云被点燃后,爆炸超压波自点火位置向四周迅速传播,点火位置对超压波的分布影响较大;控制舱爆炸时,超压强度最大,对船体超压危害最大;乘客舱爆炸强度最小,但超压中心分布在乘客舱,超压对乘客造成的危害最大;船舶舱室燃烧火焰温度主要由可燃氢气云的分布决定,燃料电池舱的火焰衰减趋势基本相同;乘客舱受到的高温危害较低,船艏舱无燃烧火焰的高温危害。 Taking a fuel cell passenger ship“Water Go Round”as the research object in this work,the process of hydrogen leakage and explosion of the pipeline in the compartment of this ship is simulated based on theFLUENT software platform.The effect of different hydrogen ignition positions on the accident is studied.The results show that the explosion shock wave propagates rapidly from the ignition position to the surrounding after the flammable hydrogen cloud is ignited,and the ignition position has great influence on the distribution of the shock wave.When the explosion position is in the control compartment,the overpressure strength is greatest,which leads to great damage to the hull of this ship.When the explosion position is in the passenger compartment,the explosion intensity is relatively low.However,considering the overpressure center is distributed in the passenger compartment,the overpressure causes great harm to people.The flame temperature in the ship compartment is mainly determined by the distribution of flammable hydrogen cloud.The flame attenuation trend in the fuel cell compartment is basically the same.The high temperature hazard to the passenger compartment is relatively low,and there is no high temperature hazard of combustion flame in the fore compartment.
