摘要

采用实验和数值方法研究了辅助脉冲电压对常压等离子体射流中电离波放电动力学的影响。辅助脉冲电压的引入改变了电势的分布。通过减小辅助脉冲电压的幅值，可以提高等离子体弹体电离波的速度和强度。通过提高辅助脉冲电压的幅值，获得了均匀分布的电子和离子密度。通过降低辅助脉冲电压的幅值，离子和电子密度集中在电离波前，从而改善了等离子体子弹的径向电场，扩大了等离子体子弹的径向尺寸。结果表明，通过提高内部电位和外加电位的振幅差，可以增强电场、离子和电子密度以及电子温度。

Discharge dynamics of ionization wave manipulated by electrical potential amplitudes in atmospheric pressure plasma jet

The auxiliary pulse voltage on the discharge dynamics of ionization wave in atmospheric pressure plasma jet is investigated by both experimental and numerical methods. The distribution of electrical potential is modified by the introduction of auxiliary pulse voltage. The velocity and intensity of ionization wave in terms of plasma bullet is enhanced by reducing the amplitude of auxiliary pulse voltage. The uniformly distributed electron and ion density are obtained by raising the amplitude of auxiliary pulse voltage. By reducing the amplitude of auxiliary pulse voltage, the ion and electron density are concentrated in the ionization wave front, which improves the radial electric field and expands the radial size of plasma bullet. It shows that the electric field, the ion and electron density, and the electron temperature can be enhanced by elevating the amplitude difference between the internal and the applied auxiliary electrical potential.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
