The potential of solar energy as a sustainable power source remains hindered by various efficiency limitations. One of the major challenges is the accumulation of dust on photovoltaic (PV) panels, leading to the decrease of the efficiency and the need for regular cleaning. To address this issue, this work aims to explore the use of ionic wind, generated by corona discharge, as an innovative method...Show More
The present study conducts a numerical investigation of the shielding effect between adjacent corona discharge electrodes in two-wire-to-plate corona devices. The primary focus of the study is to analyze the impact of mutual electrostatic interaction or shielding effect between two high-voltage wires on the electrohydrodynamic (EHD) force’s direction and magnitude, as well as the overall structure...Show More
In the present work, the spatial distribution of the electric field, the space charge density and the electrohydrodynamic force (EHD) of a stationary DC positive corona discharge in air are evaluated with the aim of characterizing their effects on the electric wind generated by the electrical discharge. Two electrode configurations have been considered: (a) wire-to-plane, and (b) two wires-to-plan...Show More
In this work, positive corona and negative corona are investigated numerically to compare their respective species productions and spatial distributions in dry air, assuming a parallel wire-to-plate electrode configuration and a stationary discharge. The electrohydrodynamic (EHD) force, which is at the origin of the EHD flow (or ionic wind), is computed by means of a simplified analytical model. T...Show More
