Abstract

Effect of gradient force on collection of diesel exhaust particles (PM) has been experimentally observed. Gradient force can drive particles only when they are in non-uniform electric field. A needle electrode was used to generate a gradient force. Observation of trapped PM on the needle electrode suggests that AC voltage application is more effective to keep the PM on the needle electrode. Is should also be noted that pearl chain formation of PM is observed, suggesting that the gradient force is suppressing the dust reentrainment. The results of this study suggest that ESP based on gradient force is feasible for collection of PM from diesel exhaust.
