摘要：
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.
