ABSTRACT:
In this article, the performance of the novel external stimulation
oscillator and the optimized self- excited oscillator has been investigated by
CFD numerical simulation. The efficiency and stimulation mechanism of the two
kinds of oscillators were analyzed in numeric form. The cycle proportion of
wall-attached jet switching time was calculated separately at different
operating frequency. Additionally the reason for the difference of two
oscillators was analyzed and explained.
