摘要

摘要：作为对双腔室自激振荡喷嘴这一新型喷嘴的探索，基于流体网络理论建立了双腔室自激振荡脉冲射流喷嘴的相似网络模型，理论分析了双腔室自激振荡喷嘴频率特性。模型计算结果表明：双腔室自激振荡喷嘴结构参数对系统的固有频率有重要的影响，系统结构参数间存在最优匹配关系，并与文献中介绍的单腔室结构参数的最佳配比关系有较大的不同，双腔室自激振荡喷嘴较单腔室自激振荡喷嘴可以提高脉冲射流峰值压力。分析结果对双腔室自激振荡喷嘴结构设计具有一定的借鉴价值。

Abstract

Abstract：As the exploration on self-excited pulsed water jet nozzle of double chambers, based on the theory of fluid network, the mathematical model of the self-excited oscillation pulsed water jet device was established, theory analyses the frequency characteristic of self-excited pulsed water jet nozzle on double chambers. The result shows that structural parameters greatly affect natural frequency of the device. And also, there has the optimized range among structural parameters which is different from the range of singlet chamber nozzle. lastly, self-excited pulsed water jet nozzle of double chambers can improved the surge pressure higher than singlet chamber nozzle in the same condition. The result is useful to the design of pulsed jet nozzle.
