Analysis on the Propulsion of Ionic Wind During Corona Discharge in Various Electrode Configuration with High Voltage Sources

Abstract

Corona Discharge (CD) in high tension wires is often considered as loss in the form of power loss, insulation failure and audible noise. The present study aims at showing the ability of CD to be used as Ionic Thruster (IT) in an electrode combination. Individual experiments were conducted on each set of electrodes (plate to plate, sphere to sphere, wire to plate & sphere to plate) with three distinct High Voltage (HV) sources (Neon Sign Transformer (NST), Cockcroft Walton Multiplier (CWM) and fly back transformer) to analyze and compare their effect on the ionic wind propulsion. After comparing the developed mathematical models for electric field and mechanical characteristics of 12 combinations of electrodes with HV sources, it highlight that the best geometrical configuration is the wire to plate Dielectric Barrier Discharge (DBD). It allows to induce ionic wind jet with max velocity of 3.75 m/s with potential radius of 176 mm. This article had also fruitful results for future research and development in the field of ionic propulsion, medical treatment of asthma patients and cooling methods for electronic devices.
