摘要：为了得到更高的空气放电离子风速度和流量，对基于空气放电离子风技术的电流体动力学（EHD）空气泵气流加速机理进行了微观说明和宏观分析。在理想流体下，对EHD空气泵进行数学建模，应用Matlab软件对EHD空气泵电气耦合过程进行了理论探讨。并建立了多极静电空气泵气流加速系统模型。研究结果表明EHD空气泵极间距、极间夹角、极间电压值和极间电流对气流速度影响较大，为后续实验研究提供理论基础。

Abstract: Mechanism of electrical hydro dynamics(EHD) air pump was micoscopic described and macroscopic analyzed based on corona wind technology for higher air discharge corona wind speed and flow. The theories of process of fluid an electric field copling in the ideal fluid were discussed. And an air acceleration model of multi-polar EHD air pump was established. The research results show that the distance between wire and plate electrodes, discharge current per unit wire length, electric potential between wire and plate have a great influence with the flow velocity of EHD air pump, provide the theortical basis of follow-up experimental study.
