Publication number: 20140263728Abstract: A system and method for reducing or increasing the mechanical structure resonance of a synthetic jet device is disclosed. A synthetic jet device includes a first plate, a second plate spaced apart from the first plate, a spacing component coupled to and positioned between the first and second plates to form a chamber and including an orifice therein, and an actuator element coupled to at least one of the first and second plates to selectively cause deflection thereof, thereby changing a volume within the chamber so that a series of fluid vortices is generated and projected out from the orifice of the spacing component.
