摘要:

在大气压下工作的微等离子体显示出许多奇特的动力学现象。这些现象之一是自脉冲,其特征在于DC驱动的等离子体放电的固有脉冲行为。本文对大气压氩气中微小薄阴极放电的自脉冲进行了数值模拟。通过一个混合等离子体模型,我们显示在预期的MHz频率范围内的放电的自脉冲,并描述其实际起源。

英文摘要:

Microplasmas operated at atmospheric pressure show a number of peculiar dynamic phenomena. One of these phenomena is self-pulsing, which is characterized by intrinsic pulsing behavior of a DC driven plasma discharge. This work focuses on the numerical simulation of self-pulsing in a micro thin cathode discharge operated in atmospheric pressure argon. By means of a hybrid plasma model we show self-pulsing of the discharge in the expected MHz frequency range and described its actual origin.
