Abstract

This paper presents results on the development of both hybrid and multifluid simulations of Hall thrusters that resolve azimuthal electron flow dynamics. Simulations are carried out for a laboratory, nominally 90 mm channel diameter discharge with an extended acceleration region for which a modest collection of experimental data exists. The simulations are intended as a tool to better understand the mechanism behind azimuthal wave-driven electron transport. Both the hybrid and fluid simulations capture azimuthal fluctuations which appear to be consistent with quasi-neutral disturbances predicted by linear analysis. The impact of such disturbances on the cross-field transport is discussed.
