平面激光诱导荧光显示火焰中OH的分布图像

Planar laser induced fluorescence imaging of OH distribution in flames

用平面激光诱导荧光技术测量了平面火焰炉、原子气化炉和超声速燃烧室的单脉冲激光诱导OH荧光。由平面荧光图可得到氢氧基相对浓度分布和它的厚度。由超声速燃烧室的OH荧光测量 ,可以看出不同时间OH分布的差别。氢氧基的PLIF图像是研究火焰结构和流场的有力工具。

The OH fluorescence imaging is obtained in flames of flat flame burner, atom gasifier and supersonic combustor by planar laser induced fluorescence(PLIF)using single laser pulse. The OH fluorescence image in the flame of supersonic combustor displays OH difference distribution at different time. OH PLIF technique provides a powerful implement for investigating flame construction and flow field.
