Full Article:

The spatially periodic system of dielectric barrier discharge actuators intended for laminar flow control on a swept wing is simulated numerically. Novel scheme of the actuator system ensuring the discharge formation only near one edge of every exposed electrode is proposed. The mathematical model of dielectric barrier discharge in air is formulated in the drift-diffusion approximation without convective transfer with taking into consideration the following volumetric reactions: the ionization of nitrogen and oxygen by electron impact, the electron attachment to oxygen, the electron detachment from negative ions of oxygen, the ionion recombination, the electron-ion recombination. Two types of boundary conditions on dielectric surface are considered for comparison: the model of instantaneous recombination and the model of finite rates of recombination and electron desorption. Numerical simulation of both conventional and novel schemes of plasma actuators is carried out for one set of problem parameters. Enhanced energy efficiency of the proposed scheme is demonstrated.
