Numerical simulation of microplasma jets and their interaction with surfaces

在环境空气中驱动的微等离子体射流最近成为科学界关注的焦点。在这种情况下，它们的应用，特别是在表面处理和改性是一个主要问题。实验成功地表明，基材的蚀刻和材料的沉积是有效的。拟议的项目旨在通过自洽数值模拟在这一领域开展工作。与研究股内进行的实验密切联系，将开发一个模拟模型，以便研究各种几何形状的等离子体射流的微放电现象、它们在环境空气中的流出物及其与表面的相互作用。

Microplasma jets driven in ambient air have recently come into the focus of scientific interest. In this context, their application particularly in surface treatment and modification is a major issue. Experiments have successfully shown that etching of substrates and deposition of materials is efficiently possible. The proposed project is intended to work in this field by means of self-consistent numerical simulations. In close connection to experiments performed within the Research Unit, a simulation model will be developed which allows to study microdischarge phenomena of plasma jets of various geometries, their effluents in ambient air and their interactions with surfaces.
