摘　　要：在实际工业生产中,连通容器内的爆炸事故屡见不鲜,而存在一定阻塞情况的连通容器内爆炸也时有发生。运用数值模拟的方法,建立了内置障碍物体的连接单根管道的容器的爆炸模型,利用甲烷-空气作为爆炸介质,获得了障碍物前后不同时刻的压力场和温度场,为实际生产中可能遇到的此类事故提供一定的理论依据和数据支持。The linked vessel explosion accidents often happen in industries. This paper uses the digital simulation way to build the explosion model for the vessel linked to a single pipe with an inner obstacle, in which methane - air is used as the explosion medium, to obtain the preasure and temperature field before and after the obstacle at different time, which can offer some theoretical and data support for this kind of accidents.

关 键 词：连通容器 压力场 温度场 爆炸
