Research on Inspiration Performance of Self-Excited and Self-Sniffed Pulsed Jet Nozzle in Submerged Condition

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.
