摘要:
将液体燃料爆炸抛撒和FAE云雾形成全过程分 2个阶段处理。在抛撒初期 ,利用运动边界处理方法 ,建立一维单相流动模型来描述爆轰产物气体和燃料液体的运动。在其后过程 ,采用两相流模型描述燃料液体与周围大气相互作用过程。数值模拟得出的云雾外形变化与实验结果符合得较好。数值模拟还给出了云雾区的物理参数变化规律
Abstract:
The w hole process of ex plosive dispersal and liquid-air cloud format ion w as divided into two regimes. For the f irst regime, a one-dimensional sing le phase model w as presented to depict the mot ion of gaseous detonat ion products and liquid fuel. And a moving boundary method w as used to t reat the outer boundary of gaseous products. For the second regime, a tw o-phase flow model w as presented to depict the interact ion of liquid and gas. The ex ternal shape of ex panding fue-l air cloud computed by numerical simulat ion is in g ood agreement w ith that of the measured. The variation of physical parameters in cloud is also show n by numerical simulation.
