摘要/Abstract

摘要： 为研究磁屏蔽对霍尔推进器磁场位形分布的影响，以轴对称环形霍尔推进器为研究对象，采用FEMM软件对各种磁屏蔽情况下的磁场分布进行仿真；结合流体模型，利用四阶龙格库塔方法对放电通道内各粒子的输运性质进行研究。结果表明：内外磁屏蔽材料高度变化时磁场位形存在最优分布；电子温度在放电通道出口附近达到最大值，约64eV。离子化频率和电子轴向有效散射频率峰值也出现在通道出口附近。

Abstract: In order to study the effects of magnetic shielding on the magnetic field configuration distribution of Hall thruster, this paper takes an axisymmetric annular Hall thruster as an example to study the magnetic field distribution under various magnetic shielding conditions by FEMM. The fourth-order Runge-Kutta method was used to study the transport properties of particles in the discharge channel. The results show that the optimum distribution of magnetic field configuration exists when the heights of inner and outer magnetic shielding materials change, and the maximum electron temperature is about 64eV near the exit plane of the discharge channel. The peak values of ionization frequency and electron axial effective scattering frequency also appear near the channel exit.
