Experimental research on the law of flame spreading in the charge bed of a central ignition tube

  • 摘要: 为了研究中心点火管火焰在药床中的传播规律,设计了可视化模拟试验平台,开展了不同点火药量、不同装药结构的中心点传火试验。采用高速图像采集系统记录了中心点火管火焰在药床中的传播过程,采用瞬态压力记录仪记录膛内压力的时空变化。结果表明,点火药量为20 g时,出火时间为0.6 ms;点火药量为30 g时,出火时间为1.5 ms;杆状装药床的传火时间平均为2.2 ms,粒状装药床的传火时间平均为3.4 ms,而杆粒混装药床的传火时间为3.1 ms。可见,点火药量对药床出火时间影响显著,较大的点火药量导致药床出火时间延长;不同装药床结构传火性能差异较大,单一杆状装药床传火性能优于单一粒状装药和杆粒混装药床,并且粒状装药床易形成气体壅塞,膛内会出现明显的压力波动现象;根据火焰传播时序位置点,利用一阶指数衰减函数拟合建立了火焰传播过程数学模型,拟合优度大于0.98。
