摘要: 为准确预测空中强爆炸产生的冲击波载荷分布，基于欧拉坐标系建立了能够模拟具有高密度比、高压力比的强激波问题的二维多介质流体数值方法。结合网格自适应技术，对1 kt TNT当量的空中强爆炸在不同爆炸高度下的冲击波地面反射过程进行了数值模拟，并考虑了真实气体状态方程和空气随高度不均匀分布的影响。计算得到了地面上距爆心投影点大尺度范围内的反射超压和冲量等冲击波载荷分布，并给出了冲击波载荷随爆高的变化规律。Abstract: In order to predict the intense blast wave in air, a multi-material numerical scheme is proposed in two-dimensional cylindrical coordinates on Eulerian grids, which can handle the blast wave problems with high ratio in initial density and pressure. Combined with the adaptive mesh technique, the propagation of blast wave produced by a 1 kt TNT intense explosion is simulated, and the effects of real gas equation of state and the nonuniform atmosphere are taken into account. The calculated blast wave parameters on the ground, such as peak overpressures and impulses, agree well with the experimental data in a wide space range, and the influences of heights of burst are analyzed.
