| 摘 要： | 以线管式静电除尘器为研究对象，利用Fluent数值模拟了离子风和外加磁场作用下中位粒径对静电除尘器（ESP）除尘性能的影响。数值结果表明：ESP对PM2.5除尘效率随中位粒径的增大呈增大的趋势，离子风和外加磁场效应均能提高ESP的除尘效率，联合作用更为明显，可为未来的ESP优化设计提供指导。

| Abstract: | Using a wire-pipe electrostatic precipitator (ESP) as a research object, the influence of the median diameter on the removal performance of the ESP under the action of ionic wind and applied magnetic field were numerically simulated using Fluent. The numerical results show that the PM2.5 removal efficiency of an ESP presents an increasing trend with an increase in the median diameter, and both ion wind and applied magnetic field improve the removal efficiency in an ESP;the combined effect is more noticeable, which can provide a guidance for the optimization of future ESP designs. |

| Keywords: | wire-pipe ESP median diameter ionic wind applied magnetic field removal efficiency |
