“…Through the corona discharge, gas molecules near corona electrode are ionized when a high-intensity electric field is applied between a highly curved corona electrode and a ground electrode. There are different corona-discharge configurations according to electrode geometries, the most relevant being wire-to-plane [2][3][4], wire-to-cylinder [5], needle-to-plane [6,7], needle-to-ring [8] or wire/needle-to-grid [9]. Research on corona discharge has been carried out in different media highlighting the investigations in atmospheric air with standard conditions, although more recently, many refrigerants such as R113 [10,11] R114 [12] R134a [13] have been studied.…”

Electro-fluid-dynamic cooling devices (EFAs) are being recognized due to their enormous advantages for their application in several industrial sectors, their performance benefits from generated ionic winds and their singular features, which make them competitive with conventional fans and heatsinks. Due to the problems in the electronics industry, where traditional refrigeration systems are not effective due to their dimensions, this study analyzes an innovative arrangement based on wire-to-plane fins by direct current (DC) positive corona discharge in atmospheric air for applications. The paper focuses on optimizing the multicriteria geometry of the electrodes. Several parameters are analyzed such as the gap between emitter and ground electrodes, the electrode materials and geometry, the diameter of the high-voltage electrode and the influence of the dielectric barriers located near the corona electrode to improve heat exchange. Experimental validation shows the potential of this arrangement related to weight, volume, non-mobile parts and silence.

In the present work an experimental investigation has been carried out on the influence of the air humidity or the water vapor injected in the incoming air flow on DC corona discharge parameters in a wire-to-planes electrostatic precipitators. To characterize the behavior of the corona discharge for both positive and negative corona, the current-voltage characteristics are subjected to an analysis using the model of Cooperman which derives the quadratic Townsend law and the general formula proposed by Meng et al. The experimental results show that the discharge current is strongly influenced by the level of air humidity. Moreover, the corona current becomes very small with the applied voltage beyond Hr = 90%, because the particle size is increased by condensation. It was demonstrated that the Coopeman model is reliable to determine the mobility of the charge carriers in this system.
