Effect of Plasma Morphology on Flow Control Using Plasma Synthetic Jet Actuators

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
The plasma synthetic jet actuator (PSJA) is a geometric variant of a plasma actuator, consisting of an annular electrode array that results in a circular region of dielectric barrier discharge plasma. In quiescent conditions, it is observed that this plasma region drives the residual fluid in the form of a vertical zero net mass flux (synthetic) jet ...

Use of Aggregate Plasma Synthetic Jet Actuators for Flow Control

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
arrangement of the plasma actuator for certain purposes, producing flow structures similar to conventional synthetic or zero net mass flux actuators. One benefit of the plasma synthetic jet actuator arrangement is that the geometry is easily configured to form either “blowing” (source like or away from the actuator) or “sucking” (sink like or toward ...

Transient ejection phase modeling of a Plasma Synthetic Jet actuator

Physics of Fluids, 2014
For several years, a promising Plasma Synthetic Jet actuator for high-speed flow control has been under development at ONERA. So far, its confined geometry and small space-time scales at play have prevented its full experimental characterization. Complementary accurate numerical simulations are then considered in this study in order to provide a ...

Experimental research on the shock wave control based on one power supply driven plasma synthetic jet actuator array

, 2020
The interaction between a ramp induced shock wave and a plasma synthetic jet actuator (PSJA) array was experimentally investigated using high-speed schlieren imaging technique. The PSJA array consisting of 10 actuators was driven by only one power supply.

PIV and Electric Characterization of a Plasma Synthetic Jet Actuator

45th AIAA Fluid Dynamics Conference, 2015
The Plasma Synthetic Jet actuator is designed for flow control applications. It generates a synthetic jet by using an electric arc created in a cavity. The velocity fields in the jet are measured by Particle Image Velocimetry (PIV). Electric measurements in the discharge circuit are carried out simultaneously. They allow to control the phase of the PIV

Aerodynamic actuation characteristic research of array plasma synthetic jet actuator

2017 8th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2017
An array PSJA is tested in this paper by using high-speed phase-lock schlieren system. The characteristic of the transient flow field is studied. The experiment shows that a series of high-speed blast waves spreads outward after discharge. These blast waves, attenuated to the local sound speed, form a wavefront, which continues to influence the flow ...

Analytic model and frequency characteristics of plasma synthetic jet actuator

Physics of Fluids, 2015
This paper reports a novel analytic model of a plasma synthetic jet actuator (PSJA), considering both the heat transfer effect and the inertia of the throat gas. Both the whole cycle characteristics and the repetitive working process of PSJA can be predicted with this model.
