| 摘 要： | 研究了常压空气中针-石蜡液面 50Hz 交流电晕放电离子风特性。交流电晕离子风能够引起液体石蜡
显著变形，随着电压升高，变形从漏斗状发展到盆状。在石蜡层厚度为 5mm 时，盆状变形最大，深度达到 5.3mm，
最大作用范围半径 18.8mm，变形产生的压强达到 48.9Pa，远远超过直流针-水电晕放电情况。随着电压升高，从
电晕放电过渡到流注放电时盆状变形依然存在，这一点明显不同于直流针-水电晕放电。研究表明交流电晕离子风
具有优良的驱动绝缘液体介质的巨大潜力。

| Abstract: | The characteristics of ionic wind induced by 50Hz AC corona discharge in atmosphere were
investigated. The experimental results indicated that AC corona ionic wind induced obvious deformation of liquid
paraffin and the funnel-shaped deformation evolved into a basin-like one with the increase of voltage. The
maximum deformation was obtained when the paraffin layer thickness was 5mm, and depth was 5.3mm, the
maximum active area radius was 18.8mm, and the pressure reached 48.9Pa, all beyond DC pin-water corona
discharge. The deformation still remained when corona discharge transited to streamer one, which was different
from DC one. The results indicate that AC corona discharge has a huge potential to drive liquid than DC one. |
