项目摘要
In order to investigate the ignition mechanism of Pulsed Combustion Jet, the chemical spices such as OH radical (306.4nm), CH radical (431.5nm), and C_2 radical (516.5nm) in the jets were measured by the chemical luminescence method. The band pass filter and photomultiplier were used to measure the emission. The measurements were made at several points in the combustion chamber and the following conclusions were obtained.1. In propagating flames, which was ignited by an ordinary spark ignition, the emission intensity of OH,CH,and C_2 radicals are strongest at an equivalence ratio of 1.0 at any measuring positions. The emissions are getting smaller in both richer and leaner mixtures. The intensity of emission of OH was strongest, and it decreases in the order of CH,and C_2 radicals.2. At the measuring position near the bottom of the combustion chamber, the rising time of the detected signals from the photomultiplier in ordinary ignited propagating flames were earlier than that from the ion probe.3. In the case of Pulsed Combustion Jet, the rising time of the detected signals from the photomultiplier and the ion probe was the same at any measuring positions except near the odifice. Near the orifice, the rising time of detected signals from the ion probe were earlier than that from the photomultiplier.
为了研究脉冲燃烧射流的点火机理,采用化学发光法对射流中的OH自由基(306.4nm)、CH自由基(431.5nm)和C_2自由基(516.5nm)进行了测量。用带通滤光片和光电倍增管测量发射。在燃烧室内的几个点进行了测量,并得到了以下结论.在普通火花点火的传播火焰中,在任一测量位置,当当量比为1.0时,OH、CH和C_2自由基的发射强度最强。无论是富混合气还是贫混合气,排放量都越来越小。OH自由基的发射强度最强,其强度依次为CH、C_2自由基.在靠近燃烧室底部的测量位置,普通点火传播火焰中光电倍增管探测信号的上升时间早于离子探针.在脉冲燃烧射流的情况下,来自光电倍增管和离子探针的检测信号的上升时间在除了靠近发射器的任何测量位置处都是相同的。在小孔附近,离子探针探测信号的上升时间早于光电倍增管。
