摘要

由于颗粒团块的形成，它们可以长时间保持不动，因此限制了电幕对颗粒减缓的作用。团块可以形成细长的颗粒链或更圆的颗粒岛。本文报道了电幕粒子团聚体的实验和计算研究。实验使用尺寸过滤的月球和火星风化层来检查团块结构和导致团块形成的条件，并绘制出表征团块大小、形状和密度的指标。计算采用离散元法和边界元法相结合的方法，探讨颗粒团聚体的形成机理。

Chains and islands - Particle agglomeration on a three-phase electric curtain

Usefulness of electric curtains for particle mitigation is limited by formation of particle agglomerates, which can remain immobile for long time durations. Agglomerates can form elongated particle chains or more circular particle islands. The paper reports on experimental and computational studies of electric curtain particle agglomerates. The experiments used size-filtered lunar and Martian regolith to examine agglomerate structure and the conditions that result in agglomerate formation, and mapped metrics characterizing agglomerate size, shape, and density. The computations used combined discrete-element method and boundary-element method to explore the mechanism for formation of particle agglomerates.
