Macroscopic Computational Model of Dielectric Barrier Discharge Plasma Actuators

<p>Recent progress in the generation and sustainment of gas discharges at atmospheric pressure has energized research in the field of plasma-aerodynamics. Plasma actuators are promising devices that achieve flow control with no moving parts do not alter the airfoil shape and place no parts in the flow. The operation of a plasma actuator is examined using a macroscopic (force and power addition) computational fluid dynamic model of a dielectric barrier discharge DBD in Fluent . A parametric approach is adopted to survey the range of requisite magnitudes of momentum and energy delivered to the flow field and to identify the effects of this localized momentum and energy addition on the flow characteristics. Simulations consider the initiation and control of flow over a flat plate in a low velocity fluid. The simulation velocity profiles are compared with the experimental observations of Corke (AIAA 2002-0350) as well as simulations of Font (AIAA 2004-3574) Boeuf and Pitchford (JAP 97 103307 2005) and Roy and Gaitonde (AIAA 2005-4631).</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
