| 摘 要： | 通过实验研究了自激振荡脉冲射流重要参数相互之间的影响关系。实验结果表明:泵压升高,射流频率增加;腔长增大,射流频率降低;而且存在一个最佳腔长使脉冲射流压力峰值达到最大。实验结果与理论分析一致。

| Abstract: | The interrelationship among the important parameters of the self-excited oscillation pulsed water jet is studied herein based on the related experiment;from which the result clearly shows that the oscillating frequency of jet increases with the increase of the pumping pressure and decreases with the increase of the length of the oscillation cavity,and then there is a optimal length of the oscillation cavity corresponding to the peak value of the selfexcited oscillation pulsed water jet.The study demonstrated that the experimental result is consistent with that from the theoretical analysis concerned. |
