| 摘 要： | 基于正离子、电子和氧负离子的三组分空气DBD等离子体动力学模型和流体动力学方程,利用有限体积方法处理控制方程空间项,采用双时间步方法模拟非定常过程,对DBD空气等离子体动力学模型方程和流体动力学方程松耦合求解,数值模拟了高压交流电源激励的低速空气等离子体流动过程。仔细研究了一个周期中真实时间步长对模拟DBD等离子体形成过程的影响,给出了等离子体的形成历程以及等离子体对低速翼型边界层流动的影响,结果在定性上是合理的。

| Abstract: | Based on the air DBD(Dielectric Barrier Discharge) plasma dynamic model,which has three types of electric particles including positive ion,electron and negative ion,and viscous flow governing equations,low speed air flow with DBD plasmas excited by high alternating current voltage source is numerically simulated by solving the loosely coupled plasma dynamic equations and viscous flow governing equations with finite volume method for their spatial terms and dual-time step method for time development process.... |
