Overview

Investigations reveal discharge dynamics and reactive species distribution in dielectric barrier discharges, highlighting non-planar surface effects.

Key Points

  • Higher discharge uniformity and reactive species distribution occur when non-planar surfaces act as cathodes, enhancing treatment efficacy.
  • Results indicated that discharge formed preferentially on the crests of higher protrusions of the non-planar surfaces, inhibiting adjacent lower protrusions.
  • A 2-dimensional plasma hydrodynamics model was validated with experimental observations, reflecting the interplay of surface properties and discharge behavior.
  • Findings contribute to a broader understanding of plasma-surface interactions, especially on non-planar surfaces relevant in biological and technological applications.
