Experiments of the Self-excited Oscillation Pulsed Jet Nozzle

由作者发明和研制成功的自激振荡脉冲喷嘴所形成的脉冲射流 ,在相同条件下与常规的连续射流相比 ,射流的峰值压力 ,冲蚀体积和有效靶距均得到明显的提高 ,作者将多年来所进行的实验室实验 (振荡腔内流体压力的测定 ;非淹没射流条件下的实验分析 ;淹没条件下自激振荡脉冲射流的性能实验及其分析 ;在淹没和非淹没条件下自激振荡脉冲射流的冲蚀效果 ;碰撞壁碰撞区域的磨损对自激振荡脉冲射流的影响等 )

The self-excited oscillation pulsed jet nozzle which proposed makes the continuous jet transform into pulsed jet . Comparing with general continuous jet, the pulsed jet has a higher peak of pressure and larger volume of erosion , therefore it increases the effective distance off of the jet under the same conditions. The laboratory and industry experiments of the Self-excited oscillation pulsed jet nozzle are introduced in the report.
