摘　　要：采用电磁场数值计算的时域有限差分法,对用于产生等离子体的对称结构激励器系统进行了电场仿真,并对等离子体流动控制机理进行了分析.得出了与理论分析一致的用于蠕动加速的对称等离子体激励器的电场分布.这对于提高蠕动加速速度和激励器的结构优化具有一定的意义.In this paper, the electric field of a symmetrical actuator system is simulated and the plasma flow control mechanism is analysed. The peristaltic acceleration process in electromagnetic field is simulated with finite-difference time-domain method and the result accurately consists with theoretical analysis, and the peristaltic acceleration mechanism is discussed. Our results may provide a theoretical basis for improving the peristaltic acceleration and optimizing the symmetrical plasma actuator configuration.
