| 摘 要： | 针对我国多泥沙河流下游水库淤积严重的现状,对自激式脉冲射流喷嘴产生脉冲射流的条件进行了分析。不同条件的对比试验结果表明:自激式脉冲射流喷嘴吸气性能影响参数有吸气管管径、吸气管根数及吸气量;在淹没条件下,对自激式脉冲射流喷嘴进行吸气处理,可使其产生脉冲射流;不同吸气条件下,装置吸气特性不同,获得较好打击效果所需的最佳吸气性能参数范围不同。

| Abstract: | According to the current situation of serious reservoir sedimentation on the downstreem of sandy river in China,the requirement of producing pulsed jet of the self-excited pulsed jet was analyzed.The results of comparative test in different conditions show that,the parameters which infect the inspiratory properties are the pipe diameter,the pipe number and capacity.When the self-excited pulsed jet nozzle is made to breathe in submerged condition,it will produce a pulsed jet.With the different inspiratory conditions,the inspiratory performances of the device are different,the range of the best inspiratory properties parameters which can receive better hitting impact are different. |
