abstract = {The collection efficiency of an electrostatic precipitator (ESP) depends essentially on the migration velocity of the particles toward the collection electrodes. This velocity is at its lowest level for particle sizes between 0.1 and 1 µm. Moreover, a recurring issue with DC discharges in air at atmospheric pressure is the build-up of significant space charges that may result in arc formation. To prevent such events, a straightforward approach consists in inserting a dielectric material between two electrodes. When subjected to an alternative electric excitation, this setup produces a discharge known as dielectric barrier discharge or DBD. This paper focuses on the study and development of a dielectric barrier discharge type electrostatic precipitators (DBD-ESP) for the capture of submicron particles. After the presentation of the basic configuration of DBD-ESP, a comparative analysis of the two primary types of DBD-ESP based on their discharge characteristics (filamentary or diffuse) is provided. Subsequently, a discussion on geometrical and electrical optimization is presented to enhance the collection efficiency. The second section of the paper explores the role of electrohydrodynamic flows (EHD) within the DBD-ESP, regarding the charging and collection mechanisms of submicron particles. Specifically, the distinct nature of EHD flows in a DBD-ESP is compared to the one observed in a conventional corona discharge ESP. Then, a theoretical model of particle movement in plane-to-plane DBD ESP allowing understanding the behavior of particles is presented, in order to show the interest of a DBD charger in the field of particle charge measurement. Finally, an exploratory study on the regeneration of subsequently polluted surfaces will be discussed at the end of this paper.},
