Anomalous electron mobility modeling in Hall thrusters
Accurate modeling of the anomalous electron mobility is crucial for successful simulation of Hall thrusters. Existing computational models for the anomalous electron mobility are used to simulate the UM/AFRL P5 Hall thruster in a 2D axisymmetric hybrid PIC-MCC code. Comparison to experimental results indicates that while these computational models can be tuned to reproduce the correct thrust or...
متن کاملModeling of anomalous electron mobility in Hall thrusters
Accurate modeling of the anomalous electron mobility is absolutely critical for successful simulation of Hall thrusters. In this work, existing computational models for the anomalous electron mobility are used to simulate the UM/AFRL P5 Hall thruster a 5 kW laboratory model in a two-dimensional axisymmetric hybrid particle-in-cell Monte Carlo collision code. Comparison to experimental results i...
متن کاملMultiscale Modeling of Hall Thrusters
Multiscale Modeling of Hall Thrusters Hall thrusters are efficient space propulsion devices that produce thrust by accelerating quasineutral plasma. The thruster consists of a channel with one end open to the ambient environment. The neutral propellant is injected at the closed end and is ionized by electrons produced by an externally mounted cathode. A radial magnetic field is applied across t...
متن کاملAnomalous electron mobility in a coaxial Hall discharge plasma.
A comprehensive analysis of measurements supporting the presence of anomalous cross-field electron mobility in Hall plasma accelerators is presented. Nonintrusive laser-induced fluorescence measurements of neutral xenon and ionized xenon velocities, and various electrostatic probe diagnostic measurements are used to locally determine the effective electron Hall parameter inside the accelerator ...
متن کاملAnomalous Transport induced by Sheath Instability in Hall Effect Thrusters
It is well recognized to ascribe the anomalous cross-field conductivity inside Hall-effect thrusters to fluctuation-induced transport due to gradient-driven instabilities (Rayleigh or electron drift) and to electron-wall interaction (near-wall conductivity). In this contribution we have performed a 2D(r,θ) Particle-in-Cell (PIC) model showing the possibility of another mechanism inducing azimut...
