摘要

摘要: 爆震管内火焰的结构非常复杂且传播速度快,需要高精度、高响应时间的测试工具.本文在单爆震试验中采用光电池测光器和离子探针测量燃烧波.研究中以高频响压力传感器为参考依据,通过测量同一截面上压力传感器、光电池测光器和离子探针之间的触发顺序,以及光电池测光器与离子探针信号的持续时间,来验证光电池测光器在爆震波测量中的可行性与精度.结果表明:光电池测光器比离子探针更适合测量爆震管内火焰传播速度.

Abstract: A measuring tool of high precision and response time is required owing to rapid flame speed and complex structure of combustion flame.The combustion wave was measured in this paper by using photoelectric detector and ion-probe.Based on the high-frequency response pressure transducer,the feasibility and precision of photoelectric detector were validated by measuring the triggering sequence between pressure transducers,photoelectric detector and ion-probes as well as the duration of photoelectric detector and ion-probe signals.The results indicate that photoelectric detector is more suitable to measure the flame speed.
