SGER: Non-Equilibrium Atmospheric Pressure Plasma Chemistry of Gliding Arc

这是探索性研究活动小额资助下的一个奖项。它是对过渡类型电弧放电的基本物理和化学的研究，有时被称为滑动电弧、滑动电弧或滑翔电弧，集中于电弧中平衡和非平衡条件之间的过渡。在该研究中，在空间和时间上定义了过渡区，确定了过渡开始时的等离子体性质以及新形成的非平衡等离子体的性质。这些特性包括放电几何形状、电路参数和局部参数，如等离子体温度和电场值。这些研究被用来评估电离机制和平衡-非平衡转变的假设。该研究包括与电流和电压波形的电测量同步的高速视频成像。滑行电弧技术被认为在环境控制和材料加工方面具有巨大的潜力，并正在进行大量的应用研究。然而，这一最近发现的现象的基本物理和化学还没有被系统地研究过。

Abstract - Fridman This is an award under the Small Grants for Exploratory Research activity. It is a study of the fundamental physics and chemistry of transition types of arc discharges, sometimes called sliding arcs, gliding arcs, or glidarcs, concentrating on the transition between equilibrium and nonequilibrium conditions in the arc. In the study, the transition zone is defined in space and time, the plasma properties at the beginning of the transition are determined as well as those of the newly formed nonequilibrium plasma. These properties include the discharge geometry, parameters of the electrical circuit and local parameters such as plasma temperatures and electric field values. These studies are used to evaluate hypotheses on the mechanisms of ionization and the equilibrium-nonequilibrium transition. The study includes high-speed video imaging synchronized with electrical measurements of current and voltage waveforms. Gliding arc technology is thought to have great potential in environmental control and materials processing, and a great deal of applied research is underway. However, the fundamental physics and chemistry of this recently discovered phenomenon has not been studied systematically.
