“…2(c) and 2(d) are the velocity contours which can prove more information for analysis. When the plasma actuator off, the single jet flow can produce symmetrical vortex structure, which is the same as result obtained in literature [12]. When the plasma actuator on, a reverse jet can be produced in the boundary layer, so that it can disturb the jet flow and then symmetrical vortex structure would be destroyed.…”

“…Bneard et al [11] also demonstrated a mixing enhancement by plasma actuators placed along the lips of the diffuser. Kozato et al [12] placed two opposite plasma actuators on the nozzle exit, they find that different actuation frequencies can change jet with and vortex morphology. However, there have been few studies on the surface dielectric barrier discharge(SDBD) plasma actuators application on jet flow control.…”

Single and twin jet flow control by surface dielectric barrier discharge plasma actuator is studied in this paper. The plasma actuator is placed on the exit of a rectangular nozzle and particle image velocimetry method is adopted to measure the jet flow velocity and conduct flow visualization. The test results prove that surface dielectric barrier discharge plasma actuator can disturb the boundary layer in the single jet, which changing the original symmetrical vortex structure, then the spreading performance can be improved. In the twin jet, the plasma actuator causes the shear layer instability, which can increase jet width significantly and show a mixing enhancement.

“…Theoretically, when DBD plasma actuator is turned ON, there is a flow disturbance occurring at the generation of plasma. The papers by Whalley and Choi [19] and Kozato et al, [10] show similar results in terms of effect of the flow control of DBD plasma actuator where there are vortex or compact spiral of smoke appeared when DBD plasma actuator is used. However, the preliminary experiment on the model in this study on visual flow field has no changes.…”

“…Supporting the visualization results done by Whalley and Choi [19], the investigation in Kozato et al, [10] uses plasma to act as a spread controller on a rectangular jet by pulsing a modulated frequency as a means to control the flow of the plasma actuator. The method of using pulse modulated frequency as the controller is very effective and there is also vortex appearing.…”

Dielectric-Barrier-Discharge (DBD) plasma actuators are one of the recent research topics that has caught worldwide attention. Plasma actuators are typically used in the aerospace field of study for their flow control and wide usage of different types of plasma actuators. DBD plasma actuator is an immobile actuator that able to be utilized for its flexibility and light weight parts. Due to the wide usage of DBD plasma, it is also able to be useful in the field of combustion in terms of air flow control. In this research, the DBD plasma actuator is tested on its ability to be applied in micro combustors based on the air flow controlling aspect, the temperature of plasma and effects of vibration of plasma. Experiments were performed in the wind tunnel with smoke generator to show the flow separation by DBD plasma actuator while infrared camera and accelerometer were used to sense the temperature and vibration respectively to investigate the effects of DBD plasma actuator on these aspects. Results shows that the plasma generated has minimal effects of the flow characteristics whereas the temperature of plasma has a maximum of 90?celcius when it is generated continuously. The vibration results indicate that generating plasma produces a small amount of vibration.
