摘要
采用气液两相方程 ,对燃料空气炸药 ( FAE)气液两相爆轰的爆轰波发展过程进行数值模拟 ,以此结果作为计算的初值 ,用三维有限体积 TVD方法和面向对象编程技术 ,模拟 FAE爆炸产生的冲击波在街道中的传播规律以及对建筑物的毁伤效应 .计算结果表明 ,三维有限体积 TVD方法描述了 FAE爆炸冲击波的反射、绕射、传播等物理现象 .在计算模型的构造和管理中 ,C++和面向对象编程技术体现出极高的优越性 .对连续边界的处理 ,采用了垂直扰动法 。
With droplet gas two phase detonation model, the shock wave ignition of FAE two phase detonation and the propagating of detonation wave were simulated. Three dimensional finite volume TVD method was used to investigate the process of three dimensional shock wave propagation in street and its destructive effects on buildings, for FAE explosion. An advanced programming technique OOP (object oriented programming) and C++ programming language were applied to numerical simulation in mechanics of explosion. A new method for continuous boundary, vertical disturbing method, was developed. By using these methods, satisfying results were got.
