“…The 1st term on the right side of equation ( 5) is the charge conduction (ion drift due to the electric field), which constitutes the primary part of the current density. The 2nd term is the charge convection (ion transport caused by the airflow), which is negligible because the airflow velocity U is approximately two orders of magnitude lower than the ion drift velocity µE [187]. The 3rd term represents the charge diffusion (ion transport caused by the ion concentration gradient).…”

Ionic wind, an induced phenomenon during corona discharge, possessing the features of silent operation and no moving parts, has a wide range of applications. Ionic wind generation is accompanied by complex physical processes, involving gas ionization, ion recombination, flow, and various chemical reactions, as well as mutual couplings between some of them. Therefore, understanding the corona discharge process and ionic wind generation is crucial for researchers and engineers to better utilize this phenomenon in practical applications. In this review, the principles of corona discharge and its induced ionic wind are presented. Subsequently, ionic wind generators (IWGs) are discussed according to their applications, and the corresponding advances based on experimental studies and numerical simulations are also reviewed. Moreover, the challenges of transitioning the ionic wind technology from laboratory studies to practical applications are discussed. These challenges include the excessively high onset voltage of the corona, ozone emission, and influence of environmental conditions. Furthermore, the mechanisms of these barriers and several effective approaches for mitigating them are provided. Finally, some future research prospects and the conclusions are presented.

“…Niewulis et al [88] also hypothesized that the EHD flow affects the collection efficiency of ESP, with the effect being greater as the size of the particles decreases. There have been numerous studies, both simulated and experimental, toward the evaluation of EHD flows inside ESPs of various electrode configurations [89]- [92]. Despite the degrading effect that EHD flow may have on the performance of ESPs, however, recent studies showed that the ozone generation of the corona discharge in air can act as a catalyst, incinerating unwanted particulates in the gas flow [93], [94].…”

Corona discharge refers to the phenomenon when the electric field near a conductor is strong enough to ionize the dielectric surrounding it but not strong enough to cause an electrical breakdown or arcing between conductors or other components. This phenomenon is unwanted and dangerous in high-voltage systems; however, a controlled corona discharge may be used to ionize a fluid and induce motion by directly converting the electrical energy into kinetic energy. Phenomena that involve the direct conversion of electrical energy into kinetic energy are known as electrohydrodynamic (EHD) and have a variety of possible applications today. This paper contains a literature review of the research regarding the EHD effects associated with corona discharges, from the first observation of the phenomenon to the most recent advancements on its mathematical modeling, as well as the advancements on specific applications, such as thrust, heat transfer improvement, boundary layer enhancement, drying, fluid pumping, and cooling.
