摘　　要：研究了离子风对除尘器内气流影响的。把放电极在电晕放电时产生的离子风用离子风集团代替,采用FLUENT流体力学数值模拟的方法,模拟了进口气流速度相同时当除尘器内存在不同电场分布时气流速度场和速度矢量的分布,使计算结果更为直观和真实,研究表明不同的放电极间距应与相应的放电电压相匹配,才可以使离子风对放电通道中的气流产生均匀的扰流作用。The influence of ion wind on the airflow was studied inner the ESP. Substituting ion wind which adhesive to the corona wire into ion wind group, the FLUENT hydrodynamics numerical simulate was adopted to simulate the distributing of ion wind group influence of airflow when the inlet velocity was the same. The results which was more straight and true show the different electrode distance should match with the corresponding discharge voltage, which can obtain even burble function caused by ion wind to the airflow in discharge channel.
