Abstract

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.
