脉冲等离子体推力器放电电离二维PIC建模与仿真
Two-Dimensional Particle-in-Cell Modeling and Numerical Simulation on the Discharge and Ionization of Pulsed Plasma Thruster
摘要
Abstract
A particle-in-cell method with Monte Carlo collision(PIC-MCC)model is established for the discharge process in pulsed plasma thruster(PPT).The ionization process in LES-6 PPT is simulated, considering the ionization collisions.According to the coupling computation of particle movement, colli-sions and electromagnetic field,the curves of current and resistance are acquired,and the distributions of plasma during the discharge of PPT are presented.Two initial conditions with and without particles pre-distribution are applied respectively to the numerical computation, implying that the results in the case with the pre-distribution are closer to the experimental results.The results in the other case tend to be in accordance with the results in the ignition process.The methods and model explored in this work provide a certain reference for PIC simulations in PPT.关键词
