| 摘 要： | 将DSMC(Direct Simulation Monte-Carlo)/PIC(Particle in Cell)流体混合算法与一维MHD双温放电模型相结合,一体化模拟NASA Glenn PPT羽流。对不同出口偏转角的羽流场进行模拟,给出了不同偏转角度下离子、电势、温度的变化情况,并与实验结果进行了比较。结果显示,该模型具有一体化(从工作过程到羽流)预测脉冲等离子体推力器羽流的能力。人工偏转角的加入,增强了羽流的扩散,使得羽流径向扩散、轴向收缩、回流减弱,同时对放电模型带来的不足有一定改善作用。 |

| Abstract: | DSMC(Direct Simulation Monte-Carlo)/PIC(Particle In Cell) fluid hybrid method and one-dimension MHD two-temperature discharge model were used to simulate the NASA Glenn PPT plume from end to end.The plume with different deflection angle at the thruster outlet was achieved in calculation,and compared with experimental results.The variations of ion,potential and electron temperature were shown.The results show that the PPT plume from end to end could be simulated with this model.The addition of deflection ang... |
