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 single-pulsed laser-induced OH fluorescence of planar flame furnace, atomic gasifier and supersonic combustor was measured by planar laser-induced fluorescence technique. The relative concentration distribution of hydroxyl group and its thickness can be obtained from the plane fluorescence chart. From the supersonic combustion chamber OH fluorescence measurement, we can see the OH distribution at different times the difference. The hydrogen-based PLIF image is a powerful tool for studying flame structures and flow fields.
