连通容器内预混气体爆炸过程的实验研究

对连通容器内预混气体爆炸过程进行实验研究，具有重要的科研和实用价值。本文通过实验室内自制的实验仪器详细研究了不同的点火位置、初始压力、初始浓度对连通容器内预混气体爆炸压力的影响。结果显示，在大容器中点火，会引起更大的爆炸压力;压力上升速率也增大很快。初始浓度对连通容器内预混气体爆炸的影响基本与单个容器中的影响一致。当初始压力增大时，连通容器的爆炸压力也随着一起增大，而且小容器比大容器增加更快。因而，在工业中，最有效的方法是隔爆，在容器和管道接口设置隔离装置，使爆炸不能通过管道传播。

Experimental investigation into explosion of premixed gases in linked vessels

It is of scientific and practical importance,to do experimental research on the process of premixed gas explosion in linked vessels.In this paper,different firing positions,initial pressures and initial densities were investigated to obtain their impacts on gas explosion pressure in linked vessels.The results showed that if fuel was burned in a big vessel,a higher explosion pressure would result in the linked smaller one.The rate of pressure rise was also rapid.The influence of initial density on the linked...
