液体燃料爆炸抛撒初期的一维数值模拟

ONE DIMENSIONAL NUMERICAL SIMULATION FOR THE INITIAL REGIME OF LIQUID FUEL EXPLOSIVE DISPERSAL

在分析液体燃料爆炸抛撒试验结果的基础上，建立爆炸抛撒近场阶段的一维轴对称单相流动的数学模型，给出变质量运动边界的处理方法，并进行编码．数值预测给出了燃料抛撒近场过程内物理量变化的详细结果．从计算所得Ｒ～ｔ曲线与实验曲线对比来看，有良好的一致性．

This paper presents a mathematical model of one dimensional gas flow with axial symmetry, which is based on the analysis of experimental results of liquid fuel explosive dispersal. Moreover, this model uses a method of moving boundary to treat moving fuel boundary. The physical parameters in the near field process are predicted by numerical simulation. The computed result is in good agreement with the experimented.
