摘　　要：离子风又称“电流体(EHD)”,是气体放电产生的高能电子推动中性粒子运动,从而在宏观上表现为流体的一种现象。由于离子风具有低噪声、低功耗、响应速度快和无机械运动部件等优点,在过去的数十年中,离子风的研究和应用取得了很大发展。该文主要从实际应用和激励器结构改进两个方面,总结和分析近年来离子风的研究结果。离子风的实际应用主要集中在食品干燥、温度控制、推进、助燃、空气净化等诸多领域,并对各领域存在的问题提出了解决方案。离子风激励器结构的改进主要解决了离子风在以上应用领域所存在的放电副产物、离子风强度低、带电粒子的影响、占用空间大和电极腐蚀等问题。最后,对离子风的未来研究做出了展望,为离子风的研究提供了思路。Ion wind,also known as“electrohydrodynamic(EHD)”,is a phenomenon in which high-energy electrons generated by gas discharges drive the movement of neutral particles,and thus appear as a macroscopic fluid.Due to the advantages of low noise,low power consumption,fast response speed,and no mechanical moving parts,ion wind has made great progress in the research and application of ion wind in the past few decades.This paper summarizes and analyzes the recent research progress of ion wind from two aspects of practical application and actuator structure improvement.The practical application of ion wind is mainly concentrated in many fields such as food drying,temperature control,propulsion,combustion support,air purification and so on.Solutions to problems in various fields are proposed.The improvement of the structure of the ion wind actuator mainly solves the problems of the discharge by-products of the ion wind,the low intensity of the ion wind,the influence of the charged particles,the large occupied space,and the electrode corrosion in the above application fields.Finally,a prospect is made for the future research of ion wind,which provides ideas for the research of ion wind.
