“…The RNG technique and the k-epsilon turbulence model are then employed to establish an incompressible, stable, and turbulent flow as Eqs. ( 7)-( 9) [1][2][3][4][5][6]. High Reynolds numbers (Re) characterize turbulent flows, which can be solved by applying the Reynolds-averaged Navier-Stokes (RANS) equations.…”

“…ESPs are generally utilized in a variety of industrial applications to collect particles that shouldn't be released into the atmosphere. Although while the particle removal efficiency for small particles (approximately 0.2 μm) has been very low, ESPs can achieve above 99% efficiency and need relatively little energy to operate [1][2][3][4][5][6].…”

“…Particles are charged by the discharge electrodes and are then attracted to and collected by the collecting plates, which have the opposite charge [7]. Ionization is achieved with the use of a high-voltage power source, and the cleaning mechanism gets rid of the particles that have accumulated on the plates [1][2][3][4][5][6]. Electrostatic precipitators (ESPs) can be categorized into two types based on the number of stages and the geometric configuration of their collection plates.…”

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.
