“…Similar physical models have been used extensively in the simulation of AC-SDBDs in atmospheric air (Ref. [7,37,38,1,36]) providing sufficient agreement with experimental findings for the purpose of this work. We note that two of the major assumptions made in the current modeling the SDBD are the neglection of photoionization and the assumption of two-dimensional evolution.…”

We show that the spatio-temporal electrohydrodynamic (EHD) force production in surface alternative current-dielectric barrier discharge (AC-DBD) actuators is strongly influenced by both the streamer regime during the positive phase and the micro-discharge regime during the negative phase. Focusing on the spatial EHD force profiles, we demonstrate that the ionic wind spatial distribution can only be explained by the positive contribution of the streamer regime. The location of maximum ionic wind is found to be directly linked with the maximum elongation of the streamers at several millimeters from the exposed electrode. In both positive and negative phases of the AC-DBD operation, residual volumetric and surface charges once again linked to the streamer formation and afterburn, result to a variety of positive EHD force zones which, when time-averaged in one AC period, contribute to the generation of the experimentally observed induced thin wall jet. Through a thorough elaboration of our numerical results, we provide an illustrative explanation of the EHD force spatio-temporal evolution, showcase the importance of streamers and retrieve a correct representation of the ionic wind spatial profiles when compared to experiments.

“…This model has been qualitatively verified for atmospheric pressure plasma discharges [16], and has been used for detailed descriptions of linear DBD plasma actuators and related EHD force production [20,21]. Models which utilise the same assumptions have been extensively validated with experimental findings [22,23].…”

“…Numerical models of DBD plasma actuators based on the fluid approximation, are most often limited to 1D, 2D or axisymmetric domains. According to a recent study [44], the fluid models tend to underestimate the jet thickness and overestimate the maximum velocity. Furthermore, the power consumption is also underestimated by about 40%-50%, which is attributed to the problem dimensionality.…”

“…Using this approach in some early studies, it was possible to estimate the electric body force distribution only qualitatively [38]. However, more recently the numerical predictions were more accurate [39][40][41][42][43][44]. These models assume a number of charge species and solve the species transport equation considering their drift and diffusion.…”

A numerical algorithm is proposed for simulation of the AC-Dielectric Barrier Discharge plasma actuators including photo-ionization. The computational bottleneck related to a very long computing time has been circumvented by suppressing the discharge pulses and proposing the mean discharge model. It incorporates an artiﬁcial damping term into the electron transport equation to suppress the formation of pulses, which signiﬁcantly accelerates the simulation. Based on the ﬂuid description of three generic species: electrons, positive and negative ions, the model accounts for the drift, diﬀusion, and reaction terms. The reaction coeﬃcients are extracted from the Boltzmann equation considering the local ﬁeld approximation. A self-sustained discharge is achieved by including a Helmholtz model for photo-ionization during the positive voltage phase, and the secondary electron emission from the metal surface, during the negative voltage phase. The proposed methodology compromises the computational burdens of the ﬁrst-principle approaches and inadequacy of the simplistic models in incorporating the problem physics. The accuracy of the proposed methodology has been validated by comparing the computational and experimental data for the electrical and ﬂow characteristics of a laboratory actuator.
