Abstract:
1. A synthetic jet actuator comprising: an electroactive cylindrical wall; a first end electroactive diaphragm; and a second end electroactive diaphragm; wherein the first and second end electroactive diaphragms are joined to the electroactive cylindrical wall at opposing ends of the electroactive cylindrical wall such that the formed chamber has a closed cylinder shape; and wherein the electroactive cylindrical wall defines an orifice therethrough; and further wherein a positive strain and a negative strain of the electroactive cylindrical wall are configured such that, when voltage is applied to the electroactive cylindrical wall, (i) a height of the electroactive cylindrical wall decreases, (ii) a thickness of the electroactive cylindrical wall increases, (iii) an inner diameter of the electroactive cylindrical wall decreases, and (iv) a diameter of the orifice decreases.
