论文摘要
在本文中，我们使用连续排放模型研究了流媒体放电的横向不稳定。我们观察到与液体中开尔文 - 赫尔姆霍尔兹不稳定性的相似之处。在强电场中，侧向长波长扰动会增长，而在放电演化过程中，小波长扰动减小。我们进行数值模拟，并对不稳定性进行渐近分析。我们的结果可以解释实验放电中观察到的增长。
In this paper we study the lateral instability of streamer discharges using a continuum discharge model. We observe similarities to Kelvin-Helmholz instability in fluids. In strong electric fields, lateral long wave length perturbations can grow while small wave length perturbations diminish during the discharge evolution. We perform numerical simulations and carry out asymptotic analysis of the instability. Our results could explain the growth observed in experimental discharges.
