| 摘 要： | 采用20 L柱状爆炸罐研究了气态ClO2的爆炸特性，得出了气态ClO2分解爆炸的体积分数下限为9.5%，不存在上限。在实验条件下，气态ClO2的爆炸压力随体积分数的增加而增大，体积分数为90%时,最大爆炸超压达到0.64 MPa，且气态ClO2的爆炸压力与其体积分数梯度有关。最大爆炸超压出现的时间随气态ClO2体积分数的增加而缩短，体积分数为10%时，最大爆压在2 195 ms时出现，当体积分数达到70%时，最大爆压出现的时间在10 ms以内，体积分数继续增加，最大爆压出现的时间基本维持在8 ms。

| Abstract: | The explosive characters of ClO2 gas were investigated in a cylindrical explosion chamber of 20 liters capacity.Experimental results indicate that the lowest volume fraction of ClO2 gas for its explosive decomposition is 9.5%,and the corresponding highest volume fraction is no existent.Under these experimental conditions,the explosion pressure of ClO2 gas increases with its increasing volume fraction,its maximum explosion overpressure is 0.64 MPa when its volume fraction is 90%,and its explosive decompositi... |
