Numerical Investigation of Scattering from a Surface Dielectric Barrier Discharge Actuator under Atmospheric Pressure [PDF]

open access: yesJournal of the Korean Institute of Electromagnetic Engineering and Science, 2018
Surface dielectric barrier discharge (SDBD), which is widely used to control turbulence in aerodynamics, has a significant effect on the radar cross-section (RCS). A four-way linearly synthesized SDBD air plasma actuator is designed to bolster the plasma

Effects of mainstream velocity and setting position on flow separation control of a curved wall using plasma actuators

open access: yesJournal of Fluid Science and Technology, 2019
Dielectric barrier discharge (DBD) plasma actuators were used for the active control of flow separation on a curved wall simulated suction surface of a gas turbine blade at three different mainstream velocities, UMS = 2.2 m/s, 4.1 m/s, and 6.3 m/s. Owing

Gurney flap effect using jet induced by plasma actuator

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Lift and drag variations by plasma actuators have been investigated under flow at low Reynolds numbers ranging from 1.7×104 to 6.6×104. Wall-normal-jet type and counter-jet type plasma actuators are attached on the pressure surface near the trailing edge

Drag reduction due to recirculating bubble control using plasma actuator on a squareback model

open access: yesMATEC Web of Conferences, 2018
Flow control on a squareback object which resembles many engineering related objects is believed to be highly beneficial. One of the flow characteristics behind the object, recirculating bubble, is known to play significant role in pressure distribution.

Modeling of dielectric barrier discharge plasma actuator [PDF]

open access: yesJournal of Applied Physics, 2007
Glow discharge at atmospheric pressure using a dielectric barrier discharge can induce fluid flow and operate as an actuator for flow control. In this paper, we simulate the physics of a two-dimensional asymmetric actuator operating in helium gas using a high-fidelity first-principles-based numerical modeling approach to help improve our understanding ...
