| 摘 要： | 以稳态等离子体推力器(SPT)羽流流场为研究对象,基于直接蒙特卡罗模拟与粒子单元混合方法建立数值模型,模拟等离子体稳态流动,研究流场特性。将计算结果与实验数据相比较,并与同类推力器羽流参数进行比较,以保证仿真可靠性。研究表明,所建立的仿真模型能够较好地预测SPT羽流电子数密度和离子电流密度等参数。

| Abstract: | A numerical model, based on the direct simulation Monte Carlo and particle-in-cell hybrid method, was developed to simulate the steady flow of plasma and study the characteristics of the plume. The computational results were copared with both experimental data and plume parameters of a congener thruster to ensure the reliability of simulation. It indicated that the simulation model was able to well predict both electron number density and ion current density of plume of SPT. |
