“…The electric potential, as illustrated by the contour lines in Figure 6.2, have a concentrated gradient at the plasma head responsible for pushing the ions downstream and away from the exposed electrode. While the plasma exhibits quasineutrality, it is not entirely uniform and a non-neutral region is formed at the head of the plasma, a phenomenon observed by Boeuf and Pitchford [27] and Murzionak et al [30]. However, the non-neutrality is restricted to the plasma head, and for the bulk of the plasma cloud N e ≈ N + .…”

“…Murzionak et al [30] also uses the configuration of Boeuf and Pitchford [27] to model plasma actuation in supersonic flow over a 50 ns time frame. The domain is restricted to within the boundary layer and thus it is assumed that the bulk flow velocity is negligible compared to the velocity of charged particles.…”

Dielectric barrier discharge (DBD) plasma actuators have been shown to influence several features of surrounding flow fields. This work models DBD plasma generation and movement in quiescent fluids. The work is restricted to plasma dynamics and does not consider the impact on the bulk flow field. A model is developed for an asymmetrically oriented DBD at 1200 V, in atmospheric conditions, operating within pure gases of N 2 , H 2 , CO 2 , CO, and H 2 O, along with various mixtures including a simplified post-combustion environment. Charged particle densities are dependent on rates of ionization and recombination, and simulations show ion densities up to 10 21 m −3 . Plasma velocity is dominated by ion mobility, with averages between 3.90 mm µs −1 and 11.59 mm µs −1 . Plasma in mixtures is found to exhibit certain qualities of each constituent species, but is generally governed by the major components of the mixture.
