Acoustic simulation of the slapping mode of piezoelectric micro-jet

In order to analysis the fluid-structure coupling acoustic properties of a designed piezoelectric micro-jet which is worked at slapping mode, the inside acoustic situation created by the vibration of vibrator is analyzed in this paper depend on the finite element software ANSYS Workbench. The effect of the properties of the liquid and shell to the ejection performance of the micro-jet is analyzed according to the simulation. The natural frequency and vibration mode of the vibrator which is soaked in the water are obtained by the wet-model analysis. The frequency response curves of the displacement and force reaction of the piezoelectric vibrator and the pressure of the nozzle are gained by the harmonic analysis.
