Effect of the duty cycle on the spark-plug plasma synthetic jet actuator

EPJ Web of Conferences, 2016
A promising novel actuator called Spark-Plug Plasma Synthetic Jet (SPSJ) has been developed in Atmospheric Plasma Research Laboratory at Niğde University. It generates electrothermally high synthetic jet velocity by using high voltage.

Jet Velocity and Acoustic Excitation Characteristics of a Synthetic Jet Actuator

Fluids, 2022
The effect of the excitation frequency of synthetic jet actuators on the mean jet velocity issuing from an array of circular orifices is investigated experimentally, focusing on the acoustic excitation characteristics of the actuator’s cavity. Two cavity

Piezoelectric Actuators for Synthetic Jet Applications

MRS Proceedings, 2003
ABSTRACTSynthetic jets have been identified and utilized widely in airflow control applications. These jets of air are usually created by the use of compressed air, or an electromechanically driven vibrating platform. All of these approaches produce desired results in airflow-control such as enhanced lift and increased maneuverability.

Plasma Synthetic Jet Actuators for Active Flow Control

Actuators, 2018
The plasma synthetic jet actuator (PSJA), also named as sparkjet actuator, is a special type of zero-net mass flux actuator, driven thermodynamically by pulsed arc/spark discharge. Compared to widely investigated mechanical synthetic jet actuators driven

Pre-switching bifurcation of a slender jet [PDF]

, 2016
In this work, we study the near-field of the jet flow exiting a slot-model with aspect ratio 7.5:1. The core of the slender jet separates into two streams which subsequently merge recomposing a single core jet.

Thermoacoustic cooling of loudspeaker-driven synthetic jet actuator

Case Studies in Thermal Engineering
To address the issue of declined cooling performance caused by the recirculation of hot jet flow into the cavity of conventional synthetic jet actuators, a loudspeaker-driven thermoacoustic-cooling synthetic jet actuator was developed by integrating a ...

Lagrangian and spectral analysis of the forced flow past a circular cylinder using pulsed tangential jets [PDF]

, 2012
We numerically investigate the influence of pulsed tangential jets on the flow past a circular cylinder. To this end a spectral-Lagrangian dual approach is completed on the basis of time-series data.

Synthetic jet actuation for load control

Journal of Physics: Conference Series, 2014
The reduction of wind turbine blade loads is an important issue in the reduction of the costs of energy production. Reduction of the loads of a non-cyclic nature requires so-called smart rotor control, which involves the application of distributed actuators and sensors to provide fast and local changes in aerodynamic performance.

Experimental research of active control optimization on a 3/4 open-jet wind tunnel’s jet section

Alexandria Engineering Journal, 2021
A 1:15 3/4 open-jet scaled wind tunnel was used for experimental test. By arranging the synthetic jet actuator around the nozzle, the experimental method was used to analyze the flow field after the active flow control was implemented. The effects of the
