Abstract:
1. A synthetic jet actuator system including a synthetic jet actuator comprising: a first wall including an inner surface, an outer surface, and a piezoelectric layer configured to expand in response to an applied electrical potential; a second wall including an inner surface, an outer surface, and a piezoelectric layer configured to expand in response to an applied electrical potential; a chamber extending between the inner surface of the first wall and the inner surface of the second wall, the chamber dimensioned to expel a fluid through an associated orifice responsive to electrical actuation of the first wall resulting in inward movement of at least portions of the first wall toward a center of the chamber and responsive to electrical actuation of the second wall resulting in inward movement of at least portions of the second wall toward the center of the chamber and to receive a fluid responsive to outward movement of the at least portions of the first wall away from the center of the chamber and outward movement of the at least portions of the second wall away from the center of the chamber; a first electrode connected to the inner surface of the first wall; and a second electrode connected to the inner surface of the second wall and positioned adjacent the first electrode to provide for formation of an arc therebetween when subjected to a minimum electrical potential therebetween to thereby enhance fluid expulsion from the chamber.
