摘要
对一维密闭容器中爆炸发展做了分析，并利用特征线方法得到了压力和密度等随时间变化的数据，为进一步泄压分析做准备。通过分析得到如下结论：①爆炸最终压力与火焰阵面波速、容器体积等无关，只与燃爆反应热有关；②爆炸压力分布随空间变化不大，增长过程与燃烧速度关系密切。
Urban gas explosion is more and more serious with the development of modern city. This article deals mainly with the development of gas explosion pressure in sealed vessels. Using character line method, we solve the partial differential equation of the explosion model. Through above analysis, two conclusions can be reached: (1)The ultimate pressure has direct relation with reactive energy; (2)The distribution of pressure varies little with space. The development of pressure is influenced by the translate speed of flame.
