| Abstract: | Air pollution caused by particles with small size has been a global concern because of threats to human health. A feasible way to remove these super fine suspended particles is using electrostatic precipitation technology. Herein, the PIV was used to measure the particle velocity distribution. By analyzing the particle motion trend in high electric field, a process of particle charging loss was observed. This phenomenon cannot be explained by current particle charging theories. Our conclusions may improve the understanding of particle charging processes. |
