Charge particles can increase the biocidal efficacy of nonthermal plasmas in indirect treatments. The aim of this study is to increase the amount of free charges produced and delivered by a surface dielectric barrier discharge fluid‐dynamics actuator. Different linear actuators and supplying conditions have been considered. Actuators were utilized to produce an ionic wind impinging an insulating target surface. Charged particles' distribution over the target was measured with and without a metallic mesh between the actuator and target itself. Linear actuators have proven to be more effective in charge delivery with respect to an annular one previously studied by our research team. A two‐dimensional electrostatic finite‐element analysis has been carried out to get a better insight into this physical behavior.

大气压等离子体致动器：增强自由电荷的传输机制

电荷粒子可以提高间接治疗中非热等离子体的杀生物功效。这项研究的目的是增加由表面介质阻挡放电流体动力学致动器产生和传递的自由电荷的数量。已经考虑了不同的线性致动器和供应条件。利用致动器产生撞击绝缘目标表面的离子风。在执行器和目标本身之间有无金属网的情况下，测量了带电粒子在目标上的分布。事实证明，相对于我们的研究团队先前研究的环形致动器，线性致动器在电荷输送方面更为有效。进行了二维静电有限元分析，以更好地了解这种物理行为。
