摘　　要：从三维全NS方程出发,用二阶迎风TVD格式,针对贴地和近地三种不同的爆源位置,研究了两团云雾爆炸后爆炸场的相互作用。计算结果表明:本文的方法可模拟多爆源爆炸后冲击波的传播和爆炸场复杂的波系结构。Upwind TVD scheme is used to solve the 3D fully N S equations which describe explosion field generated by the fuel air explosives (FAE).The studies are done on three specified locations of the FAE sources that are close to or on the ground.The propagation and interaction of the blast waves produced by each explosion source can be shown clearly from the pressure contours.The pressure time history at any point and the pressure distribution at any time in the explosion field can be determined by numerical simulation in this paper.The slide shows of the pressure distribution is heplful to evaluate the overpressure distribution.
