Numerical Analysis on the Cymbal and Half Cymbal Membranes for Piezoelectric Synthetic Jet Actuator
In the field of flow boundary layer control,synthetic jet or zero mass jet is a high potential method at present.However,the application of traditional synthetic actuator with plane membrane has been limited so much by the reason of its low jet output velocity.In this paper,two kinds of new style of piezoelectric ceramic-metal composite material membrane,cymbal and half cymbal style,and solid and annular styles of piezoelectric patch are used to improve the driving capability.The finite element models are built and the numerical results are obtained using ANSYS system.From numerical results,the distortion value caused by cymbal style membrane is obviously larger than which caused by plane membrane in the same condition.And the distortion value caused by the membrane with annular piezoelectric is larger than which with solid piezoelectric in the same condition.In addition,for optimizing the structure of half cymbal style membrane,the dimensions of membranes are changed and numerical calculations are done to investigate the influence of different dimensions on the largest distortion value of the membrane.Then the structure of half cymbal style membrane is optimized to improve the driving capability of SJA.And the experiment validates the correctness of the theoretical analysis.
