Multi-Electrode Plasma Actuator to Improve Performance of Flow Separation Control

Flow Control of Leading Edge Separation on Airfoil Using Dbd Plasma Actuator

Flow Control over Conical Forebody with Port Pulsed Plasma Actuator

A study using plasma port single-pulsed discharge is performed on the flow control of asymmetrical vortices over slender conical forebody. The different circumferential steady and unsteady pressure distributions are measured in the wind tunnel test. At the same time, the local side force, the increment of local side force and the overall side force and moment are calculated with the circumferen...

Multi-Actuator Vibration Control Shaker Performance Dynamic Testing Equipment

Sensing and control of flow separation using plasma actuators.

Single dielectric barrier discharge plasma actuators have been used to control flow separation in a large number of applications. An often used configuration involves spanwise-oriented asymmetric electrodes that are arranged to induce a tangential wall jet in the mean flow direction. For the best effect, the plasma actuator is placed just upstream of where the flow separation will occur. This a...

Reduction of Electrostatic Control Voltage with a Tri - Electrode Actuator †

We present a new tri-electrode topology for reducing the control voltage for electrostatic actuators. Conventional parallel plate actuators are dual-electrode systems, formed by the MEMS structure and the drive electrode. By placing a perforated intermediate electrode between these elements, a tri-electrode configuration is formed. This topology enables a low voltage on the intermediate electro...
