摘要: We present the results from 2D fluid modeling of key roles controlling glow dielectric barrier discharge (DBD) structure. A uniform DBD can be sustained at lower frequency when space charge reaches uniformity due to plasma decay, while patterned structure appears above a critical is nonuniform. The patterns start electrode edge where electric field significantly distorted, characterized by seed electrons that always form ahead surface charges. formation associated with lateral inhibition local increase distribution volume plays role in result formed
