Abstract: A plasma actuator of the present disclosure comprises a plate electrode; a needle electrode positioned at a height above the plate electrode and a distance away from the plate electrode; and a voltage source connected to the needle electrode. Application of a signal from the voltage source to the needle electrode forms surface corona discharge around a tip of the needle electrode, and air flow driven by the corona discharge from the tip of the needle electrode is induced at a surface of the plate electrode. Accordingly, the air flow that is created can be used to cool a surface, such as a circuit board, a heat exchanger, etc.
