我们研究了大气压氩气或空气等离子射流与移动固体基底上脂肪烃液膜的相互作用。流体动力射流-液体相互作用引起较低膜厚的轨迹。化学等离子体-表面相互作用氧化液体，导致表面张力局部增加和液膜自组织重新分布。我们开发了一个数值模型，可以定性地再现实验中观察到的流型的形成、不稳定性和粗化。监测液体流动具有作为等离子体-液体表面相互作用的原位、空间和时间解析诊断工具的潜力。
We studied the interaction of atmospheric-pressure plasma jets of Ar or air with liquid films of an aliphatic hydrocarbon on moving solid substrates. The hydrodynamic jet-liquid interaction induces a track of lower film thickness. The chemical plasma-surface interaction oxidizes the liquid, leading to a local increase of the surface tension and a self-organized redistribution of the liquid film. We developed a numerical model that qualitatively reproduces the formation, instability and coarsening of the flow patterns observed in the experiments. Monitoring the liquid flow has potential as an in-situ, spatially and temporally resolved, diagnostic tool for the plasma-liquid surface interaction.
