Hybrid Modeling of a Hall Thruster Using Hyperbolic System of Electron Conservation Laws
نویسندگان
چکیده
The hyperbolic-equation system (HES) approach is applied to the calculation of a Hall thruster using the hybrid particle-in-cell (PIC) method. The HES approach enables accurate computations of magnetized electron fluids in quasi-neutral plasmas with a simple structured mesh. SPT-100 thruster is assumed as the calculation condition. The calculation results indicate that the Bohm criterion is satisfied for the channel walls. Also, the Boltzmann relation is confirmed in the region of strong magnetic confinement. These facts prove that the HES approach accurately calculates the boundary condition of wall sheath, and the characteristics of magnetized electron fluid in Hall thrusters.

The comparison of two high-order semi-discrete central schemes for solving hyperbolic conservation laws
This work presents two high-order, semi-discrete, central-upwind schemes for computing approximate solutions of 1D systems of conservation laws. We propose a central weighted essentially non-oscillatory (CWENO) reconstruction, also we apply a fourth-order reconstruction proposed by Peer et al., and afterwards, we combine these reconstructions with a semi-discrete central-upwind numerical flux ...

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...

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...
