摘要

真空电弧由阴极点和混合区、电弧柱和阳极区组成。在真空电弧模型中,特别是扩散电弧模型中,应考虑分离射流和混合区。本文通过仿真研究了多阴极点真空电弧射流的混合和相互作用。为了研究真空电弧射流的混合和相互作用,需要一个稳定的三维磁流体动力学(MHD)模型。为了了解不同参数对真空电弧射流混合和相互作用的影响,对具有电流、真空电弧射流角度、有无电磁方程和倾斜射流等不同参数的模型进行了仿真。以六个圆柱形射流为模型,研究了多阴极点真空电弧射流的混合和相互作用过程。根据模拟结果,给出并分析了离子数密度、温度分布、流速和离子压力。

Modeling and simulation of mixing and interaction of multi-cathode spot vacuum arc jets
Vacuum arc consists of cathode spot and mixing zone, arc column and anode zone. The separate jets and the mixing zone should be considered in the model of vacuum arc, especially the diffuse arc. In this paper, mixing and interaction of multi-cathode spot vacuum arc jets were studied through simulation. To investigate the mixing and interaction of vacuum arc jets a steady 3D Magneto-Hydro-Dynamic (MHD) modeling was required. In order to find out the influence of different parameters on mixing and interaction of vacuum arc jets, models with different parameters such as currents, angel of vacuum arc jets, with or without electromagnetic equations and tilted jets were simulated. Six cylindrical jets were modeled to study the process of mixing and interaction of multi-cathode spot vacuum arc jets. Based on the simulation results, the ion number density, temperature distribution, flow velocity and ion pressure were given and analyzed.
