Modelling of the Characteristics of Synthetic Jet Actuators
35th AIAA Fluid Dynamics Conference and Exhibit, 2005In this paper, a simple static compressible model and a dynamic incompressible model for circular synthetic jet actuators are described. They are used to investigate the effect of changing actuator geometrical and operating parameters on the magnitude of jet peak velocity at the orifice exit.

Optimization of Synthetic Jet Actuators
41st Aerospace Sciences Meeting and Exhibit, 2003Abstract : This paper describes the optimization of a piezoelectric-driven synthetic jet actuator based on a Lumped Element Modeling (LEM). To simplify the problem, this papers splits the optimization problem into two parts. First, a constrained optimization of the cavity volume and orifice dimensions of two baseline synthetic jets, each with a given ...

On Plasma Synthetic Jet Actuators
44th AIAA Aerospace Sciences Meeting and Exhibit, 2006The 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.

A Jet Formation Criterion for Synthetic Jet Actuators
41st Aerospace Sciences Meeting and Exhibit, 2003This paper proposes and validates a jet formation criterion for synthetic jet actuators. The synthetic jet is a zero net mass flux device, adding additional momentum but no mass to its surroundings. Jet formation is defined as a mean outward velocity along the jet axis and corresponds to the clear formation of shed vortices.

Incompressible Flow Model of Synthetic Jet Actuators
AIAA Journal, 2006A performance prediction model is developed for circular synthetic jet actuators in which the flow is assumed to be incompressible. Accurate prediction of the behavior of synthetic jets is challenging because of their complex unsteady nature. The importance of dimensionless stroke length and Reynolds number in determining the characteristics was ...

Lumped Element Modelling of Synthetic Jet Actuators
3rd AIAA Flow Control Conference, 2006In this paper, a lumped element model of synthetic jet actuator is presented and used to predict the temporal variation of the jet velocity. Unlike the previous model reported in the literature, in this model the mechanical movement of the diaphragm is decoupled from the fluid phenomenon in the actuator cavity to allow the modelling of fluid mechanics ...

A Design of a Mechanical Synthetic Jet Actuator
Applied Mechanics and Materials, 2012To show the influence of the synthetic jet on the wake of a cylinder and the aerodynamics performances, a piston-rod-crank actuator was designed to provide a synthetic jet with amplitude up to 20% of the free-stream velocity from the wind tunnel. The rod is driven in rotation by an electrical motor with variable frequency and maximum speed of 2800 rev ...

Research on Plasma Synthetic Jet Actuator
AIP Conference Proceedings, 2011Circular dielectric barrier surface discharge (DBDs) actuator is a new concept of zero mass synthetic jet actuator. The characteristic of discharge and flow control effect of annular‐circular plasma synthetic jet actuator has been studied by means of of numerical simulation and experiment.
