Effects from ion thruster plume have long raised concerns. However, little work has systematically analyzed the influencing parameters in the ion thruster plume simulation. This paper analyzes LIPS 200 ion thruster plume simulations about the influencing parameters. The numerical simulations are carried out by a hybrid particle-in-cell (PIC) method and the direct simulation Monte Carlo (DSMC) method. The PIC method is employed for the plasma dynamics, and the DSMC method is used for collisions. Simulation results were compared in detail to obtain the variation of the results with the parameters. Besides, experimental data were compared to simulation results to optimize the parameters. Finally, with these researches, the optimal parameters are obtained.

A parallel, three-dimensional electrostatic PIC code is developed for large-scale electric propulsion simulations using parallel supercomputers. This code uses a newly developed immersed-finite-element particle-in-cell (IFE-PIC) algorithm designed to handle complex boundary conditions accurately while maintaining the computational speed of the standard PIC code. Domain decomposition is used in both field solve and particle push to divide the computation among processors. Two simulations studies are presented to demonstrate the capability of the code. The first is a full particle simulation of near-thruster plume using real ion to electron mass ratio. The second is a high-resolution simulation of multiple ion thruster plume interactions for a realistic spacecraft using a domain enclosing the entire solar array panel. Performance benchmarks show that the IFE-PIC achieves a high parallel efficiency of ≥ 90%

This paper presents a new algorithm for modeling spacecraft-plasma interactions: the hybrid grid immersed finite element particle-in-cell (HG-IFE-PIC) algorithm. This algorithm is extended from IFE-PIC and is designed to efficiently and accurately simulate the interactions between nonuniform plasmas and complex objects. In HG-IFE-PIC, the meshes used by the IFE field solver and PIC are decoupled, and the IFE solver uses a Cartesian-tetrahedral mesh that is stretched according to local potential gradient and plasma density. It is shown that the application of HG-IFE-PIC with a stretched IFE mesh can achieve approximately the same accuracy as IFE-PIC while significantly reducing the memory requirement and computation time required for large-scale PIC simulations of spacecraft-plasma interactions.Index Terms-Electric propulsion plume, immersed finite element particle-in-cell (IFE-PIC), spacecraft-plasma interaction.
