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. This particular geometry creates a zero-net mass f...

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 piezoelectric diaphragm, is conducted using two differe...

In the present paper the characterization of the flow field generated by means of a submerged gaseous jet exited by means of a coaxial synthetic jet has been investigated. The purpose of this investigation is to infer the aerodynamic interaction of the two fluid structures that play an interesting role in several industrial applications like jet actuator, flame stability in the combustor for mi...

This research is an effort to demonstrate the applicability of miniaturized synthetic jet (microjet) technology to the area of thermal management of microelectronic devices. Synthetic jets are jets which are formed from entrainment and expulsion of the fluid in which they are embedded. Design issues of microjet cooling devices are discussed along with characterization of excitation elements and...

In this paper we will establish the affine bundle theorem in our synthetic approach to jet bundles in terms of infinitesimal spaces Dn’s. We will then compare these affine bundles with the corresponding ones constructed in our previous synthetic approach to jet bundles in terms of infinitesimal spacesD’s both in the general microlinear setting and in the finite-dimensional setting.

This paper aims to understand how a micro synthetic jet actuator works effectively to prevent the boundary layer flow from laminar separation aused by adverse pressure gradient. Experimental results showed that synthetic jets were effective when the forcing frequency was a lower frequency f the Tollmien–Schlichting (T–S) wave, which received amplification from the base flow. They demonstrated t...
