基于Ansys的平板型介质阻挡放电仿真与研究

Simulation and Study of Flat-plate Dielectric-barrier Discharge Based on Ansys

针对微型原子化器中平板型介质阻挡放电进行了仿真与研究.主要对不同介质阻挡材质、不同介质厚度、不同放电间隙、不同激励电极形状以及不同激励电压对放电特性的影响进行了研究.仿真表明:介质阻挡材质介电常数越大,越容易获得较大的放电密度;选用圆形激励电极获得的放电密度远大于选用方形激励电极;相对而言,较薄的介质阻挡材质更容易获得较大的放电密度;较小的放电间隙更利于提高放电的密度和放电的均匀度等.

A flat-plate type dielectric barrier discharge of micro-atomizer was studied based on Ansys software in this paper.The effect of the discharge characteristics on different factors,such as the material and thickness of dielectric barrier,the discharge gap,the shape of exciting electrodes and the exciting voltage were studied.The simulation results show that if the greater dielectric constant of dielectric barrier material was chosen,and the larger discharge density would be easy to obtain.To choose the round exciting electrodes can get more discharge density than the square exciting electrodes. Correspondingly,to select the thinner dielectric barrier material can obtain the more discharge density easily,and to design the smaller discharge gap can be propitious to enhance the discharge density and improve the uniformity of discharge.
