“…Similarly, Ramadhan et al [93] also obtained the space charge density and electric field of the integrated EHD system mentioned in section 3.1.1. Taghavi Fadaki et al [188] numerically investigated the effect of the electric field on the heat transfer enhancement of a corona device configuration comprising a single fixed emitting wire situated at the centerline of the channel and different grounded electrode arrangements, which are of two types: wire and plate. Our research group [90] employed a full 3D multiphysical numerical method, which was implemented through a combination of two commercial software products, namely, ANSYS-Fluent and COMSOL Multiphysics, to investigate the coupled effects of the electric field, airflow, and heat transfer in needle-ring type ionic wind devices with multi-needle electrodes connected in parallel for cooling an electronic component.…”

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.
