介绍了用于燃烧场温度、组分、火焰构造和流场速度等参数测量的相干反斯托克斯喇曼散射、自发振动喇曼散射、激光诱导荧光和OH示踪测速实验系统,给出了在预混火焰、高能固体推进剂瞬态燃烧场和超声速高温流场测量的部分实验结果,并分析了激光作用区域燃烧场温度、主要组分及流场速度的分布和火焰构造。
This paper overviewed recent progress in the evolution of four different diagnostic concepts: coherent anti-stokes Raman spectroscopy, laser-induced fluorescence, vibrational Raman scattering, and hydroxyl tagging velocimetry. Techniques based on these measurement concepts can monitor a variety of parameters including temperature, species concentration, and velocity. The experimental results were given by these laser-based methods in premixed flame, solid propellant burning, and supersonic flowfields.
