Abstract:A novel external stimulation oscillator was recommended and its characteristics of high efficiency and easy oscillation were proved by CFD simulation and experiment. The superiority and difference of process mechanism of the oscillator compared with self-stimulation oscillator were analyzed. The geometric parameters of the new oscillator that could trigger and maintain efficient oscillation and the minimum stimulating flow were determined. It was also indicated that the redundant quantity of the stimulating flow would not decrease the total pressure retention rate as the energy of stimulating flow could be merged into the main jet.
