Supersonic Cavity Flow Control Using Plasma Synthetic Jet Actuators

AIAA Journal
A spanwise array of plasma synthetic jets (PSJs) is employed to control the cavity flow at Mach 2.0 with the aim of mixing enhancement. The time responses of the flow to control are diagnosed by a high-speed schlieren imaging system and a planar particle imaging velocimetry (PIV) system.

Plasma Synthetic Jet for Flow Control

40th Fluid Dynamics Conference and Exhibit, 2010
The necessity of having an efficient actuator to control flow has driven ONERA to develop a pioneer actuator called Plasma Synthetic Jet (PSJ). This actuator was inspired by the John Hopkins University device. It produces a high exhaust velocity jet using electrical power.

On Plasma Synthetic Jet Actuators

44th AIAA Aerospace Sciences Meeting and Exhibit, 2006
The term plasma actuator refers to an asymmetric arrangement of two electrodes (typically rectangular strips) separated by dielectric material that can be used as active flow control devices. A plasma actuator design consisting of an annular electrode array, the plasma synthetic jet actuator (PSJA), is experimentally investigated in this paper.

Flow control with plasma synthetic jet actuators

Journal of Physics D: Applied Physics, 2007
This paper presents an experimental investigation of the characteristics of a plasma actuator design for flow control consisting of an annular electrode in quiescent and flat plate boundary layer flows. In quiescent flow, the circular plasma region produced on actuation was observed to generate a vertical zero-net mass flux (or synthetic) jet, hence ...
