Improvement of Fluidic Oscillator Characteristics by Synchronization with Vibrating Elastic Structure

摘要

We introduce a design concept of fluidic oscillator whose frequency can be tuned using controlled vibration ofan elastic structure, such as a piezoelectric element, by the means of synchronization. We use phase reductiontheory to estimate the synchronization condition and compared it with results from the actual perturbed full statedynamics. Furthermore, the resulting changes due to synchronization show that the proposed method improvesthe physical characteristics of the oscillating flow, in particular for liquid mixing application.
