摘要/Abstract

摘要： 在喷孔-喷孔和环缝-喷孔对撞式喷注模型发动机上,采用H₂/O₂热射流切向喷注的起爆方式进行了H₂/air组合的连续旋转爆震试验,根据高频压力测量和高速摄影观测结果对爆震波传播过程进行了分析。试验发现了短暂的和可长时间维持的双波对撞传播现象,在该传播模式下燃烧室内存在两个爆震波头,但传播方向相反,周期性发生对撞,其高频压力振荡特征跟测压点距对撞点的夹角相关。初步分析了双波对撞传播过程的形成机制,认为在爆震波顶部能否形成混合气体层是实现该传播模式的关键。 

Abstract: Experimental research on the H₂/air continuous rotating detonation wave has been carried out on two model engines, which use the injector-injector and slot-injector impinging injection schemes respectively. Tangentially injected H₂/O_2hotshot jet has been used to ignite the engines successfully. Based on the PCB measurements and optical observations, the detonation wave propagation process has been analyzed. Both transient and long-time lasting two-wave collision propagation phenomena have been observed. Under the two-wave collision mode, there are two detonation waves propagating along the opposite direction in the combustor, colliding with each other periodically. Its high frequency pressure distribution presents different oscillation characteristics, which is mainly influenced by the angle between the pressure sensor location and the collision point. It is believed that to realize this rotating mode there should be an annular zone of fresh H₂/air mixtures located at the top of the detonation wave. 
