“…However, the flat collecting plate ground electrode shape is assumed in many investigations. Nonetheless, a few experiments have been motivated to assess electrohydrodynamic (EHD) flow in ESPs utilizing non-flat collection plates [15,[19][20][21][22][23][24]. Different shapes of collecting plates were numerically studied such as C-type, wavy, triangular, and W-type, and crenelated plates [1-6, 19, 25-27].…”

Electrostatic precipitators (ESPs) play a crucial role in removing harmful particles in various industries. Ongoing studies continuously strive to improve their performance and efficiency, leveraging the inherent advantages of ESPs. Researchers are exploring various types of collecting and discharge electrodes to achieve this. This study specifically focuses on comparing two types of collecting electrodes, Semicircular Corrugated Plates (SCPs) and inverted Semicircular Corrugated Plates (InvSCPs), against Flat Plates (FPs) as a reference case. Three distinct forms of ESPs were simulated, and the SCP and InvSCP designs were evaluated against the FPs, specifically assessing the impact of modifying the collecting electrode design on key electrostatic precipitator characteristics, such as electrical field distribution, space charge density distribution, particle trajectories, and particle collection efficiency. Notably, the study found that using SCP resulted in the highest particle collection efficiency compared to InvSCP and FP for the same range of particles.

“…This formula shows that the efficiency of electrostatic precipitator is directly proportional to the particle driving speed and the area of the dust collecting plate, and inversely proportional to the gas flow rate. Liu et al [14] used experimental and numerical simulation methods to study the effect of different types of expansion and contraction spoiler (ECS) arrangement on the distribution of electric field intensity, flow velocity, particle motion pattern and dust removal efficiency. The results showed that ECS structure formed vortex with low speed and increased the retention time of dust particles, thus obviously improving the dust removal efficiency.…”

Ionic wind is a phenomenon of electrofluid movement in electrostatic precipitator, which changes the motion state of flue gas and dust in electrostatic precipitator to a certain extent. In order to study the influence of ionic wind on air flow characteristics in electrostatic precipitator, this paper constructed a numerical model of electric field-flow field coupling and compared the impact of electro-hydro dynamics (EHD) effect on flue gas flow state at different inlet velocities. In addition, this paper analyzed the influence of EHD effect on the motion trajectories of particles with different sizes. The results showed that the EHD effect changed the flue gas flow field near the anode plate at 0.3m/s inlet velocity, forming an obvious reflux region; this phenomenon weakened when the inlet velocity increased. At the same time, the EHD effect reduced the dust removal efficiency when the particle radius ranged from 0.25 μm to 1 μm.
