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 compared 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.
