Modeling of Dielectric Barrier Discharge Plasma Actuator
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 2-D asymmetric actuator operating in Helium gas using a high-fidelity first principles-based numerical modeling approach to help improve our understanding of the physical mechanisms associated with such actuat...
متن کاملSurface Decontamination by Dielectric Barrier Discharge Plasma
Background: Dielectric barrier discharge (DBD), a source of non-thermal plasma, is used in surface decontamination. Objective: To study the effect of DBD plasma treatment, we evaluated the effect of plasma exposure time on inactivation of Bacillus subtilis. Results: Applying the DBD plasma to the culture of B. subtilis caused complete sterilization of the surface without any thermal effects. In...
متن کاملCharacterization of Electrohydrodynamic Force on Dielectric-Barrier-Discharge Plasma Actuator Using Fluid Simulation
Wall-surface jet induced by the dielectric barrier discharge (DBD) has been proposed as an actuator for active flow control in aerodynamic applications. Discharge plasma evolution of the DBD plasma actuator was simulated based on a simple fluid model, in which the electron, one type of positive ion and negative ion were taken into account. Two-dimensional simulation was conducted, and the resul...
متن کاملSurrogate Modeling for Characterizing the Performance of Dielectric Barrier Discharge Plasma Actuator
The dielectric barrier discharge (DBD) plasma actuator offers promising opportunities for flow control because it does not require mass injection and involves no moving mechanical components. In order to gain better understanding of the impact of the materials and operational parameters on the performance of the DBD actuator, and to facilitate design of effective control schemes, the surrogate ...
متن کاملCapabilities of the dielectric barrier discharge plasma actuator for multi-frequency excitations
The natural instability mechanisms are inherent in most of the laminar and turbulent flow configurations. Usually, these instabilities result in the formation of flow structures occurring at diverse spatial and time scales. An effective control requires an actuator able to bring momentum transfer over a wide range of frequency to act on these instabilities. Promising results are expected for su...
