Limitations of the DBD effects on the external flow
This paper provides a comprehensive analysis of the viscous effects for the DBD operation. Maximum DBD induced flow velocity is estimated based on the conservation laws without the viscous effects. It is demonstrated that inclusion of the viscosity leads to the twice smaller maximum DBD induced flow velocity. The possibility to increase maximum induced flow velocity by use of a series of DBDs is considered. The significant dependence of the DBD induced flow on the spatial distribution of the DBD body force is shown. Based on the study of the boundary layer profile, it is demonstrated that the DBD force should not only be maximized, but also generated at the optimum location for optimum DBD performance. The possibility of using DBD as a de-icing device is also analyzed. 2010 by authors and U. S. government. Published by the American Institute of Aeronautics and Astronautics, Inc.
