摘　　要：通过试验对低压大流量自激式脉冲射流喷嘴装置主要性能参数(结构参数和运行参数)进行了系统研究,得出了低压大流量自激式脉冲射流装置最佳结构参数和运行参数的范围,设计的高性能自吸气式自激脉冲射流喷嘴装置在淹没条件下能够有效提高射流打击力.Main performance parameters（structural parameters and operating parameters） of the low-pressure high-flow self-excited pulsed jet nozzle were studied systematicly by test.The optimal structural parameters and the range of operating parameters for the low-pressure high-flow self-excited pulsed jet device were obtained.In submerged conditions,the nozzle designed could effectively enhance the jet striking force.
