The purpose of this project is to develop an approach to modeling of dielectric barrier discharge plasma actuators working in a continuous mobile environment. The review of methods of numerical simulation of the dielectric barrier discharge plasma actuators working in a continuous medium, and the analysis of characteristic time scales of the plasma flow and aerodynamic processes selected class of mathematical models, which can play a plasma source of exposure to the surrounding air with sufficient accuracy and acceptable time-consuming. Mathematical model describing the transient electric and aerodynamic processes in the operation of the plasma actuator was developed on the based on a physical model of the dielectric barrier discharge. Finite volume numerical algorithm for solving plasma electrodynamics equations together with the equations of viscous incompressible flow, including turbulence in curvilinear coordinates on moving grids for modeling of dielectric barrier discharge was developed. The developed approach is simulated the effect of dielectric barrier discharge plasma actuators work on quiescent air. As a result of numerical simulation of the impact of plasma actuators on the analysis of a stationary air flow field, the potential distribution of the electric field, the density of the resulting charge and velocity components in the computing field. The developed approach is simulated driving force of the impact as a result of dielectric barrier discharge on the cylinder, which is in quiescent air. The possibility to reduce the drag coefficient of the cylinder using plasma actuators by suppressing Karman vortex street.
