摘　　要：在自激脉冲射流装置非淹没试验研究的基础上,对自激脉冲射流装置应用于水下淤泥处理进行了淹没工况(淹没水深0.5 m)试验研究,分析了下喷嘴直径、腔径、腔长及下喷嘴长度对装置性能的影响规律。研究表明:在淹没条件下,对上喷嘴直径一定时的某一工况,存在最优下喷嘴直径、最优腔长及最优腔径使装置性能最佳;最优下喷嘴长度与非淹没情况相同。Based on the experimental research of the self-oscillating pulsed jet device in un-submerged condition, the research in submerged condi- tion （ submerged depth 0.5 m） was conducted to deploy the research of pulsed jet technology＇ s application in the treatment of underwater silt, and we analyzed the influence of the nozzle diameter, lumen diameter, cavity length and the length of lower nozzle on the device performance. The re- suits show that, in the submerged condition, the optimal lower nozzle diameter, the optimal cavity length and the optimal lumen diameter of certain upper nozzle diameter exist to make the best device performance, and the optimal lower nozzle length is the same to the un-submerged condition.
