摘要:
基于磁流体动力学模型完成了直流10kA大电流电弧的仿真计算，获得杯状电极间电弧的温度、气压、电弧电压和气流场速度的分布参数，分析出杯状电极间电弧的发展过程与稳定燃弧状态。结果表明，电极间电弧经历电弧膨胀和稳定燃烧两个阶段，电弧最终稳定在电极间燃烧而不向外部运动。通过对比实验数据与仿真数据，验证了仿真的准确性与有效性。
Abstract:
A high current arc of 10 kA direct-current was simulated based on the magneto hydrodynamics mode, obtaining the distribution parameters of temperature, gas pressure, arc voltage and airflow field velocity of the arc between cup electrodes. The development process of arc between cup electrodes and its stable arcing state were analyzed on the basis of the above data. Studies show that arc between electrodes underwent two stages: arc expansion and stable combustion, and finally kept burning between electrodes instead of moving outward. The accuracy and effectiveness of the simulation model were verified through comparison of experimental data and simulation data.
