英文摘要：

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.
