摘要
用平面激光诱导荧光 (PLIF)技术测量了氢 /空气和煤油 /空气超音速燃烧室氢氧基的荧光以及背景辐射光的图像。实验结果表明 ,PLIF是鉴别对燃烧性能起关键作用的燃料 /空气混合过程的有效手段 ,发现在超音速燃烧室中PLIF氢氧基主要集中在凹腔区域 。
Planar laser induced fluorescence (PLIF) technique is utilized to measure the images of hydroxyl radicals (OH) fluorescence and spontaneous emission in hydrogen/air and kerosene/air supersonic combustion. The results show that PLIF has been an efficient approach for identification of fuel/air mixing and combustion process. It is found that large number of OH radical is concentrated in the cavity range of the combustor, it is helpful to understand the mechanism of the cavity as the flame holder in supersonic combustor.
