Simulation analysis of combustion and explosion hazards of aviation fuel in cabin

  • 摘要: 不同舱室结构内航空油料的燃爆参数存在差异,为了解和掌握不同结构舱室内航空油料的燃爆危害性,运用计算流体动力学(computational fluid dynamics,CFD)方法对不同结构航空油料舱室内的航空油料蒸汽燃爆问题进行了数值模拟。结果表明:密闭航空油料舱中的航空油料蒸汽预混燃爆时,油舱各处压力分布较均匀,无隔板密闭舱室和含不完全分割隔板密闭舱室内航空油料的最大燃爆压力分别为0.76、0.74 MPa,即舱室内的不完全分割隔板对航空油料燃爆时所产生的最大压力无显著影响;隔板等特殊结构的存在使舱室内部产生了气流漩涡,增大了燃料消耗的速率,导致火焰面传播速度及压力上升速率增大,舱室内各处燃料的质量分数由火焰面决定。
