基于激光诱导荧光法的同轴射流火焰中羟基自由基、甲醛、发热率与一氧化氮的二维可视化测量

Two-Dimensional Visualization Measurement of Hydroxyl Radical, Formaldehyde, Heat Release Rate and Nitric Oxide in Co-Flow Jet Flame Based on Planar Laser Induced Fluorescence Technology

  • 摘要: 对现有单一组分羟基自由基(OH)平面激光诱导荧光系统(PLIF)装置进行功能扩展研发, 在不增加激光器和探测器的情况下, 拓展了甲醛(CH2O)、发热率(heat release rate, HRR)和一氧化氮(NO)三个参量的PLIF成像测试模块.同时, 利用所研制的同轴射流火焰装置开展了所建立的多参量PLIF测量技术的实测验证, 获得了同一火焰轴截面上的OH、CH2O、HRR与NO的二维分布.测试系统可广泛用于各种火焰结构测试及污染物NO产生机理分析, 为燃烧反应动力学模型及火焰结构理论研究提供有力的试验数据支撑.

     

    Abstract: The research and development of the expansiom of function based on the existing single-component hydroxyl radical (OH) planar laser induced fluorescence technology (PLIF) has been carried out, i.e., the three parameters such as formaldehyde (CH2O), heat release rate (HRR) and nitric oxide (NO) PLIF diagnostic module were established without the need of more lasers and detectors. At the same time, a co-flow jet flame burner has been developed and used to carry out the measurement to verify the established multi-parameters PLIF measurement technology. The two-dimensional distributions of OH, CH2O, HRR and NO of the same flame in the axial section were obtained. The diagnostic system can be further widely used to measure structures of various flames and to analyze the produced mechanism of pollutant NO, as well as to provide experimental data to support the theoretical study on combustion reaction kinetic model and flame structure.
