| 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. |
