Abstract
Numerical study on the electrohydrodynamic flow, particle transport, and particle deposition characteristics in a spike-plate multi-electrode electrostatic precipitator (ESP) was carried out in this work. The interaction between the secondary electrohydrodynamic flow and main airflow resulted in a complex turbulent flow structure. The intensity of vortices near the spiked electrodes and particle collection efficiency increased with increasing applied voltage and decreasing inlet flow velocity. The injection location also had a complex influence on the particle transport and deposition characteristics. Furthermore, the deposition morphology of particles that were injected from different inlet locations was reported.
