Airfoil Leading and Trailing Edge Separation Control Using SDBD Plasma Actuators
Wind tunnel experiments were conducted to understand boundary layer separation control on airfoils. The objective of this research was to better implement flow control strategies with single dielectric barrier discharge (SDBD) plasma actuator designs for airfoils that exhibit both leading and trailing edge stall characteristics at realistic flight speeds and Reynolds numbers. The NASA energy ef...

The objective of current paper is 3D simulation of turbulent, developing flow and unsteady within a circular duct in presence of the body force vector persuaded by Dielectric barrier discharge (DBD) plasma actuator inside the surface of geometry for the first time. This article aims at investigating of applying plasma actuator to control separation with special arrangement of electrodes. For th...
متن کاملRetrospective Cost Adaptive Flow Control Using a Dielectric Barrier Discharge Actuator
Retrospective cost adaptive control is applied to low Reynolds number aerodynamics around an SD7003 airfoil with a dielectric barrier discharge (DBD) actuator located near the leading edge. The adaptive control algorithm uses knowledge of Markov parameters to capture information about any nonminimum-phase zeros in the dynamics. In this paper, we explore the impact of the adaptive controller on ...
متن کاملHigh-performance computing-based exploration of flow control with micro devices.
The dielectric barrier discharge (DBD) plasma actuator that controls flow separation is one of the promising technologies to realize energy savings and noise reduction of fluid dynamic systems. However, the mechanism for controlling flow separation is not clearly defined, and this lack of knowledge prevents practical use of this technology. Therefore, large-scale computations for the study of t...
متن کاملApplication of the airflow control by electro-hydrodynamic actuator
The technique used to control the airflow is based on the electro-hydrodynamic actuator which is also called plasma actuator. This actuator ensures the airflow control thanks to the electric wind created by the electrical corona discharge. This ionic wind is developed at the profile surface tangential to the initial free airflow so that it has a significant effect on the boundary layer flow. Th...
