Combustion initiation of flammable gas mixture in a closed volume by high power HF and CO2laser

  • 摘要:研究了封闭圆柱石英腔中化学计量CH4∶ O2混合气的燃烧试验。使用了非定域脉冲HF 触发和直接使用脉冲CO2 器助燃两种引燃方法。第二种引燃方法是使用小剂量的可以强烈吸收脉冲CO2 辐射的SF6来加热易燃混合气。研究了燃烧过程,并确定了燃烧辉光的谱线特征。试验表明,即使在小体积反应器中,固定数量反应气的快速 加热也能够极大地加速燃烧进程并达到混合气燃烧的爆炸模式。得到了阈值情况下沿腔轴的初始温度分布。
