摘要
进行了M=2超音速流中横喷氢的自动着火及燃烧非定常过程实验研究,用高速纹影摄影、壁面动态和静态压力测量仪及壁温热电偶等进行了测量。得到了喷嘴后回流区壁压随时间的变化规律,以及壁压和壁面秒温升沿轴线的变化趋势。获得了来流空气总温和喷氢量对自动着火过程的影响。
ith a high speed camera and schlieren optical system, dynamic and static pressuretransducers, temperature sensors, auto-ignition and non-steady processes in supersonic air flow with injecting transversely hydrogen are studied by tests. Wall pressures changing with time within auto-ignition processes in recirculating zone downstream the injector, and wall pressures rises in axial direction are measured. Effects of the airstream's total temperature and the amount of injecting hydrogenon auto-ignition processes are considered.
