Comparing PIC/MCC Simulations and Experimental Data for the PPS ® X00-ML Hall Thruster IEPC
Résumé
Validating simulation results against experimental measurements of Hall thruster (HT) performance has long been a major challenge. Few examples of successful comparison do exist in the literature. In this work, we compare the results of three codes: (1) fluid stationary, (2) fluid non-stationary, and (3) two dimensional Particle-in-Cell/Monte Carlo-Collisions (PIC/MCC), with experimental measurements on the Laboratory Model (ML) thruster PPS ® X00-ML HT by Safran Spacecraft Propulsion. The results show that fluid and PIC/MCC simulations can successfully reproduce some macroscopic measured quantities, such as discharge current, thrust, and specific impulse. Simulations also offer the possibility to inquire the state of the plasma inside the thruster, gaining a deeper insight on the plasma characteristics along the thruster axis.
