本研究探讨表面阻挡放电（SBD）阵列的电极宽度如何影响沉积功率，诱导流和传递到下游样品的活性物质的空间分布。它示出，减少电极宽度增加了在一个固定的工作电压的功率密度，引起的振荡流的加剧高达200%，导致局部化的流动在每个放电间隙的重叠。当SBD阵列和处理表面之间的距离减小时，这种强化将物种通量中的波纹引入下游表面。针对不同的电极宽度和SBD与治疗表面之间的距离，确定并量化了对流驱动输送和扩散驱动输送之间的过渡。这项工作表明，输送通量中的波纹与对流驱动输送有关。
This study investigates how the electrode width of a surface barrier discharge (SBD) array affects the deposited power, the induced flow and the spatial distribution of reactive species delivered to a downstream sample. It is shown that decreasing electrode width increases the power density at a fixed operating voltage, causing an intensification of the oscillatory flow by up to 200%, resulting from the overlap of localized flows at every discharge gap. This intensification introduces ripples in the flux of species to a downstream surface when the distance between the SBD array and the treated surface is reduced. A transition between a convection‐driven delivery and diffusion‐driven delivery was identified and quantified for different electrode widths and distances between SBDs and the treated surface. The work shows that the ripples in the delivered flux were associated with convection‐driven delivery.
